Question

If pressure is kept constant and the temperature of a gas is doubled, what will happen
to the volume?
A. It will double.
B. It will remain constant
C. It will decrease to 25% of its original volume.
D. It will decrease by half.

Answer 1

I believe it's (A). It will double.

Explanation:

Charles law states that the volume of an ideal gas is directly proportional to the absolute temperature at constant pressure. (Charles's law).

Answer 2

The pressure, volume, and temperature are the main factors of the ideal gas. At constant pressure when the temperature is doubled, then volume also gets doubled. Thus, option A is correct.

What is an ideal gas law?

The ideal gas law has been known as the law that relates the pressure, volume, moles, and temperature of the gas particles. The relationship between the volume and the temperature of the gas was given by Charle's law.

According to Charle's law, the volume and the temperature have been known to have direct relation when the factor of pressure is said to be constant. If they exhibit the direct relation then doubling the temperature will double the volume of the gas.

Therefore, option A. the doubling of temperature doubles the volume is correct.
