Question

When the pressure and number of particles of a gas are constant, which of the following is also constant? Explain answer please

the ratio of the volume and temperature in kelvins

the difference of the volume and temperature in kelvins

the sum of the volume and temperature in kelvins

the product of the volume and temperature in kelvins

Answer 1

the sum of the volume and temperature in kelvins.

Answer 2

Answer : The correct option is, the ratio of the volume and temperature in kelvins

Explanation :

According to the Charles' Law, the volume of gas 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)

or,

`(V)/(T)=k`

where,

V = volume of gas

T = temperature of gas

k = constant

As per question, when the pressure and number of particles of a gas are constant then the ratio of the volume and temperature in kelvins.

Hence, the correct option is, the ratio of the volume and temperature in kelvins
