Question

The volume of a given quantity of a gas must increase if: the temperature and pressure increase the temperature and pressure decrease the temperature increases and the pressure decreases the temperature decreases and the pressure increases

Answer 1

C.) If the Temperature increases and pressure decreases....

Answer 2

Answer: the temperature increases and the pressure decreases

Step-by-step explanation:

Boyle's Law: This law states that pressure is inversely proportional to the volume of the gas at constant temperature and number of moles.

`P\propto (1)/(V)` (At constant temperature and number of moles)

Thus as pressure and volume are inversely related, as pressure decrease, the volume increase.

Charles' Law: This law states that volume is directly proportional to the temperature of the gas at constant pressure and number of moles.

`V\propto T` (At constant pressure and number of moles)

Thus as temperature and volume are directly related, as temperature increase, the volume increase.
