The minimum battery size that would be needed to power the refrigerator for two days if there is no sun will be about 12V 300Ah.

It depends on your location, the season, and if the fridge is new and efficient or old and inefficient. However, a refrigerator typically requires 1000 watt hours per day. With around 500 watts of solar power and a 12V 300Ah (3600Wh) battery, you could easily run it for a few days without the sun. Your battery must be able to handle the load without running out of power. You would need a battery bank of at least 300ah at an average. Below, you can see how this was decided. 24 hours of 66 Watts every hour equals 1584 Watts. 12 volts and 1584 watts equal 132 Ah. So for 48 hours it will be 264 Ah. Therefore for refrigerator to run for couple of days it needs battery size of about 300ah.

1. The new volume of 500 mL of gas is approximately 385 mL.

2. The new pressure is 345.45 torr.

The relationship between pressure, volume, and temperature of a gas is described by Boyle's law, which states that the volume of a gas is inversely proportional to its pressure, provided that the temperature remains constant. To find the new volume, we need to use the equation:

V1 * P1 = V2 * P2

Where V1 is the initial volume, P1 is the initial pressure, V2 is the final volume, and P2 is the final pressure. Substituting the given values, we get:

V2 = V1 * (P1 / P2) = 500 mL * (750 torr / 980 torr)

So, the new volume of 500 mL of gas is approximately 385 mL.

The relationship between pressure, volume, and temperature for a fixed number of gas particles can be described by the ideal gas law: PV = nRT, where P is the pressure, V is the volume, n is the number of particles, R is the gas constant, and T is the temperature (in Kelvin). In this problem, we are given the initial pressure, volume, and temperature, and asked to calculate the final pressure after the volume expands.

2. Since the number of particles (n) and temperature (T) are constant, we can rearrange the equation to find the final pressure after the volume expands:

P1V1 = P2V2

P2 = P1 * (V1/V2)

Plugging in the given values:

P2 = 500 torr * (650 mL / 900 mL) = 345.45 torr

So the new pressure of the helium is 345.45 torr.

A peninsula can be created by the water level rising or lowering, which may expose or hide areas of the land. A peninsula may also be formed through the rise or descent of a geographical mass.

Arabian, Deccan, Indo-China, Horn of Africa, Alaskan Peninsula, Labrador Peninsula, Scandinavia, The Balkans, The Iberian Peninsula, and The Kamchatka Peninsula are the 10 largest peninsulas.

When the sea level pushes up on the land and slowly recedes over many years, erosion occurs, resulting in the formation of a peninsula. In addition, land masses are frequently only partially surrounded by water as a result of melting glaciers and an increase in tropical storms, which raises sea levels.

A peninsula is a piece of land that is bordered by water on three sides. The phrase "nearly an island" is derived from the Latin paene insula. Florida is the most obvious peninsula in the US. Although Alaska is quite big and has many of its own peninsulas, it also satisfies the description.

The properties that cause some magmas to be more felsic than others are the relative abundances of different elements and minerals that crystallize at different temperatures, changing the chemistry of the magma.

Felsic magmas are characterized by a high abundance of silica (SiO2) and aluminum (Al) and low abundances of iron (Fe) and magnesium (Mg). The high silica content of felsic magmas means that they have a higher viscosity and lower melting temperature compared to mafic magmas, which have a lower silica content.

During the cooling and solidification of magma, minerals with different melting temperatures will crystallize at different times. For example, silicates with a high silica content, such as feldspar and quartz, will crystallize before mafic minerals, such as olivine and pyroxene. This changes the composition of the remaining liquid magma and can cause it to become more felsic.

Therefore, the relative abundances of different elements and minerals in magma and the temperatures at which they crystallize can influence the felsic or mafic nature of the magma.

Explanation:

The temperature of 175 °Fahrenheit in degrees Celsius is 79.4 °Celsius.

Temperature is the degree to which a thing is hot or cold. Temperature is a measure of a system's average kinetic energy. As particles in a substance travel faster, their kinetic energy increases, raising the temperature of the system. Heat is defined as the energy exchanged when two bodies of differing temperatures come into contact. Temperature is a quantity that indicates a body's thermal condition (i.e., the degree of hotness or coldness of the body). When two bodies of differing temperatures come into touch, it defines the direction of heat transfer.

Here,

The temperature of hot water in degrees Celsius can be calculated by using the formula:

C = (F - 32) * (5/9)

where C is the temperature in degrees Celsius and F is the temperature in degrees Fahrenheit.

Plugging in the given temperature of 175 ∘F, we get:

C = (175 - 32) * (5/9)

Sulfuric acid (H2SO4) has a molecular weight of 98.08 g/mol. To calculate the number of moles of sulfuric acid in the solution, we divide the mass of sulfuric acid (2.355 g) by its molecular weight (98.08 g/mol).

Next, we divide the number of moles of sulfuric acid by the volume of the solution in liters to obtain the molarity of the solution. The final volume of the solution is 50.0 mL, which we need to convert to liters by dividing by 1000.

The molarity (M) of the solution can be calculated using the following equation:

M = (number of moles of solute) / (volume of solution in liters)

Plugging in the values, we get:

M = (2.355 g / 98.08 g/mol) / (50.0 mL / 1000 mL/L) = 0.0478 mol / 0.05 L = 0.957 M
