Question

Find the new volume of the gas, when kelvin temperature and pressure of a fixed amount of gas is doubled?

• A. Twice its original volume
• B. Unchanged
• C. One-half its original volume
• D. One-fourth its original volum
• E. Four times greater than its original volume

Answer 1

The correct option is B Unchanged

The new volume of the gas, when kelvin temperature and pressure of a fixed amount of gas is doubled is unchanged.
Volume is directly proportional to the ratio $\frac{T}{P}$.
$V\propto \frac{T}{P}$
When kelvin temperature and pressure of a fixed amount of gas is doubled, the ratio $\frac{T}{P}$ is unchanged and the new volume is same as old volume.
