Density can be calculated by dividing the mass of an object by its volume. Water has a density of 1g/ml. If an object’s density is greater than 1 g/ml it will sink and if its density is less than 1g/ml it will float?
Answer:
yes
Explanation:
The density of an object determines whether it will float or sink in another substance. An object will float if it is less dense than the liquid it is placed in. An object will also sink if it is more dense than the liquid it is placed in

EXPERIMENT: DETERMINING VOLUME
Here are your goals for this lesson:
Measure a common geometric shape in centimeters and record answers
Calculate volume for the geometric shape
Utilize the method of displacement to determine volume
Answer questions and summarize results
If you ever dropped something into a full pail of water, you might have noticed that some of the water flowed over the edge of the pail. Whatever was dropped into the pail took up some of the space that had been filled by the water. As a result, some of the water was displaced from (pushed out of) the pail. The amount of space that matter takes up is called the volume of that matter. Thus a giant boulder has more volume than a small rock. Any unit of matter, large or small, solid, liquid, or gas, takes up space and therefore has volume.
In this experiment, you will attempt to determine the volume of two objects, using two different methods, listed below:
1. For an object of uniform shape having linear sides or a common geometric shape, measure the object and determine the volume mathematically.
2. For an irregularly shaped object that cannot be measured easily or does not consist of uniform geometric shapes, determine the volume of water it displaces. The volume of water displaced equals the volume of the object as long as the object does not absorb or dissolve in water.
When measuring the volume of water in a graduated cylinder or similar container, be sure you read the lowest point of the curved surface of the water, the meniscus. Study Figure 1 to find the correct level.
1. Find the volume of an object with linear sides or a common geometric shape.
These supplies are needed: a metric ruler and an object with linear sides or a common geometric shape
A. Volume equals length times width times height (V = l × w × h). The amount of space that an object takes up is its volume.
B. Measure in centimeters (cm) the length, width, and height of the object and record your answers.
Note: Be sure you included the units (cm) with each measurement.
C. Multiply the length by the width by the height. This is the volume of the object.
Volume = l × w × h = _____ × _____ × _____ = _____ cm3
Since you went from linear measurement (cm) to cubic measurement (cm3 ), the units change and your answer will be in cubic centimeters (cm3 ).
2. Find the volume of an irregularly-shaped object.
These supplies are needed: string, water, small rock, graduated cylinder
A. Pour water into a graduated cylinder until it is about half full, stopping at one of the level marks on the cylinder.
B. Read and record the level of the water. This reading is the volume of the water. Be sure you are reading at the lowest point of the curved surface or meniscus. Study Figure 1 above to see how to read the correct level.
C. Tie the string on the rock and lower the rock completely into the water. Let it settle at the bottom.
D. Record the level of the water with the rock in it. This reading is the volume of the water and the rock.
E. Find the volume of the rock by subtracting the reading of the water from the reading of the water and the rock.
(water and rock) - (water) = _____ cm3. Your answer is the volume of the rock.
3. Compose a scientific summary of your method, observations, data, and conclusions. In addition, be sure to answer the questions below in your report.
Why does the first method for determining volume work only for a regular-shaped object?
Will the second method for determining volume work for any object or just an odd-shaped one? Why?
Is one method of measurement more accurate than the other? Why or why not?
Would the displacement method of measurement work for a cube of sugar? What about a cork? Why?
What did you find out from this investigation? Be thoughtful in your answer.
Anyone who answers improperly will be reported please only answer if you have the answer. Thank You :))
10 points and Brainliest for best answer! goood luck!
Explanation:
(Ques- A) Why does the first method for determining volume work only for a regular-shaped object?
(Ans- A) Because the method requires precise dimensions of objects for result, which is not possible for irregular shaped objects.
(Ques - B) Will the second method for determining volume work for any object or just an odd-shaped one? Why?
(Ans-B) It will work for both regular and irregular shaped objects since both displace equal volumes of water.
(Ques - C) Is one method of measurement more accurate than the other? Why or why not?
(Ans-C) Both are pretty accurate, with some experimental errors which may creep in accidentally.
(Ques- D) Would the displacement method of measurement work for a cube of sugar? What about a cork? Why?
(Ans - D) No, the method would not work because sugar being soluble, will dissolve in water.
No, the method would not work because sugar being soluble, will dissolve in water. Cork is less dense than water so floats on it, with only part of it submerged in water, resulting in displacement of less volume of water than actual volume of Cork.
(Ques-E) What did you find out from this investigation? Be thoughtful in your answer.
(Ans- E) I learnt about determining volume of different objects from this investigation. (Sorry, I know its not a very thoughtful answer)
is this right ? if it’s wrong correct me
Explain how the amount of pressure created by a smaller piston can be the same as the pressure created by a larger piston?
Answer:
The larger piston will travel a smaller distance but it will exert a larger force. The formula can be rearranged: P=F x A. Because the pressure (P) is the same in the whole system (which is the hydraulic jack), the force (F) will be larger where the area (A) of the piston is larger!
The relation between pressure, force and area shows that pressure is inversely proportional to the area while directly proportional to the force.
What is pressure?
The force was applied perpendicular to an object's surface per unit area across which that force is spread is known as pressure. The pressure gauge in relation to the higher pressures is known as gauge pressure. Pressure is measured in a variety of ways.
Although the larger piston travels a shorter distance, it exerts a greater force. It's possible to rearrange the formula
P=F / A.
where, the pressure (P) in the entire system is the same, the force (F) will be greater where the piston's area (A) is greater.
Therefore, it can be seen that pressure is inversely proportional to the area while directly proportional to the force.

When two or more atoms bond together it is called what?
Answer:
Two or more atoms may bond with each other to form a molecule. When two hydrogens and an oxygen share electrons via covalent bonds, a water molecule is formed. Chemical reactions occur when two or more atoms bond together to form molecules or when bonded atoms are broken apart.
Explanation:
When two or more atoms bond together it is called a molecule.
Explanation:
When two or more atoms are bonded together they form a molecule.If the atoms bonded together are of the same element then it is said to be the molecule of that element.For example, sulfur has a molecule of S_8 under normal conditions
If the atoms bonded together are of the different elements then it is said to be the molecule of that specific compound.For example, ammonia is a compound made up of nitrogen and hydrogen, its molecule consists of one nitrogen atom bonded to three hydrogen atoms, NH_3.
So, we can conclude that when two or more atoms bond together it is called a molecule.
