Answer:

I believe its True

Explanation:

The given statement stating that conductors  allows electricity to flow easily through them is true owing to their property of conduction.

Conduction is defined as a process as a means of which heat is transferred from the hotter end of the body to it's cooler end.Heat flows spontaneously from a body which is hot to a body which is cold.

In the process of conduction,heat flow is within the body and through itself.In solids the conduction of heat is due to the vibrations and collisions of molecules while in liquids and gases it is due to the random motion of the molecules .

When conduction takes place, heat is usually transferred from one molecule to another as they are in direct contact with each other.There are 2 types of conduction:1) steady state conduction 2) transient conduction.According to the type of energy conduction is of three types:

1) heat conduction

2) electrical conduction

3)sound conduction

Answer:

4.427 × 10⁵

Explanation:

In mathematics, rounding up a number is a way to get a more simpler figure but not too distant from the original number. Rounding up a whole number like this (442722) to significant figures means having only four non-zero digits in the figure i.e. 442722 ~ 442700.

This means that 442722 has been rounded up to 4s.f. Hence, to use scientific notations to represent our answer, we count the number of decimal places from right to left i.e.

442700 = 5 decimal places if the point is between 4 and 4 i.e. 4.427

Therefore, the figure 442700 can be written as 4.427 × 10⁵ using scientific notation.

Answer:

When water freezes, its molecules move farther apart, making ice less dense than water. This means that ice will be lighter than the same volume of water, and so ice will float in water. ... As some of the water vapor cools, we see it as a small cloud called steam.

Answer:

yes the Bohr model predicts their spectra accurately

Explanation:

The Bohr model based on one electron system

The atom H  has a single atom and the ion Be+3 has a single atom as well and this proves that the Bohr model predicts their spectra accurately .

also apply the equation model to further explain

E = [tex]\frac{-(z^2) (2.18 * 10^{-18}j) }{n^2}[/tex]

z = atomic number

for H the value of z = 1

for Be+3 the value of z = 4

when this values are substituted into the equation above

E =  [tex]\frac{-(1) (2.18 * 10^{-18}j) }{n^2}[/tex] ,   E = [tex]\frac{-(4) (2.18 * 10^{-18}j) }{n^2}[/tex]

this results show that the energy  level of Be+3 is higher than the energy level of H by a factor of 16 , and this shows that their line patterns are similar

If a substance has a relatively low melting point (below 400ºF), then it is either molecular polar or molecular non-polar

If a substance has a high melting point, then it is either metallic, covalent network, or ionic

The stronger a substance’s bonds, the higher its melting point

Answer:

liquid

Explanation:

There are three states of matter and these are the following:

1. Solid

2. Liquid

3. Gas

"Liquid" has particles that show movements in-between to that of the solid and liquid. The forces between these particles are weaker when compared to the forces of particles in solid. This allows it to take the shape and volume of the container without actually changing its volume. If you pour a liquid unto a heart-shape container, it will take the shape of the heart as its form (it has no fix shape).

Answer:

150.6 Joules

Explanation:

Calorimetry problem must be solved by the calorimetry formula.

Q = c . m . ΔT

ΔT = Final T° - Initial T°

c = specific heat (Notice, that in the unit we have K as unit for T°, and the T° is in °C. We don't need to make the conversion, because is a Δ)

For example 100°C - 50°C = 50°C

373K - 323K = 50 K

So let's replace data given: Q = 0.82 J/g.K . 12.58 g . (38.2 - 23.6)

Q = 150.6 Joules

We assume no heat lost by sourrounding

Answer:

The average for the first row: 18.67

The average for the second row: 32

Explanation:

It's easy to find the average. Add all the numbers than divide it by the total number of values in the set.

Example: 12, 8, 2, 6

Add all the numbers and you get 28. Then divide 28 by four because there is 4 numbers you added (you added 12, 8, 2, and 6). So you get 7, and that's the average!

moles C5H12 used = 10.0 g C5H12 x 1 mol/72 g = 0.139 moles pentane

moles O2 consumed = 0.139 mol C5H12 x 8 mole O2/1 mol C5H12 = 1.11 moles O2

mass O2 consumed = 1.11 moles O2 x 32 g/mole = 35.5 g O2

The distance traveled by light : 1.86 x 10⁵ miles

Explanation:

Given

speed of light=v=1.86 x 10⁵ miles/s

time=1 s

Required

distance of light travel

Solution

The motion of light can be considered as motion that has a constant velocity so that it can be classified as a straight, regular motion that has no acceleration

Can be formulated

[tex]\tt \boxed{\bold{d=v\times t}}}[/tex]

For the distance traveled by light in the above problem becomes:

[tex]\tt d=1.86\times 10^5~miles/s\times 1~s\\\\d=\boxed{\bold{1.86\times 10^5~miles}}}[/tex]

Answer:

P = 795.77 Mpa

Explanation:

Given that,

Force exerted by the hammer, F = 10⁴ N

The nail can be considered as a circle with radius of [tex]2\times 10^{-3}\ m[/tex]

We need to find the pressure exerted on the wall. Pressure is equal to force acting per unit area. So

[tex]P=\dfrac{F}{A}\\\\P=\dfrac{10^4\ N}{\pi \times (2\times 10^{-3})^2}\\\\P=795774715.45\ Pa[/tex]

We know that, 1 MPa = 1000000 Pa

So, P = 795.77 Mpa

So, the pressure exerted on the wall is 795.77 Mpa.

The basic unit of chemistry is atom.

Matter is all what is present around. Atoms and compounds are all made of very small parts of matter. Matter is defined as anything that has mass and takes up space (it has volume).

Atoms are the smallest unit of matter. It has a tiny atomic nucleus, which is in the center of the atom and contains positively charged particles called protons and neutral, uncharged, particles called neutrons. On the outer side of the atom is a “cloud” of electrons which are negatively charged particles that orbit around the nucleus.
