• None of these.

when a gas is compressed at constant temperature

• speed of molecules increases

• collision between molecules increases

• speed of molecules decreases

• collision between molecues decreases

the molar volume of CO₂ is maximum at

• NTP

• 0^{0 C} and2 atm

• 127⁰C and1 atm

• 273⁰C and 2 atm

kinetic energy of a gas depends on

• molecular mass

• atomic mass

• equivalent mass

• none of these

when gas are heated from 20⁰C to 40⁰C at constant pressure their volumes

• increases by same magnitude

• become double

• increases in the ratio of their molar mass

• increases but to a diffrent extent

the gas constant R is constant for
