The pressure of a gas depends on the ____ and ____ of the gas.
dexar [7]

The pressure of a gas depends on the temperature and volume of the gas.

<h3>Ideal gas equation</h3>

PV = nRT

Where

  • P is the pressure
  • V is the volume
  • n is the number of mole
  • R is the gas constant
  • T is the temperature

From the equation given above, we obtained the following:

PV = nRT

Divide both sides by V

P = nRT / V

R is constant and n = 1

P = T / V

Thus, we can see that the pressure (P) is dependent on the temperature (T) and the volume (V)

double replacement reaction or double displacement reaction,

Explanation:

double replacement reaction, double displacement reaction, is a chemical process involving the exchange of bonds between two non-reacting chemical species which results in the creation of products with similar or identical bonding affiliations

Classically, these reactions result in the precipitation of one product.

in thía case it is AgCl

How much energy is required to heat a frozen can of juice (360 grams- mostly water) from 0 degrees Celsius ( the temperature of
Usimov [2.4K]

Answer:

1,100,160J or 262.94 kcal

Explanation:

The juice is frozen at 0 degrees Celsius and I assume that it will become gas at 100 degrees Celsius. So we change the form of the water from solid to liquid, then to gas. That means we have to find out how much heat needed to change water form too, not only the heat needed to increase its temperature.

The latent heat of water is 4.2J/g °C while the heat of fusion is 334 J/g and the heat of vaporization is 2260 J/g. The energy needed will be:

360g * 4.2J/g °C * (110-0°C ) + 360g * 334 J/g + 360g * 2260 /g = 1,100,160J or 262.94 kcal.
