At constant volume, for a fixed number of moles of a gas, the pressure of the gas increases with the rise in temperature due to

A

decrease in mean free path

B

increase in molecular attraction

C

increase in rate of collisions amongst molecules

D

increase in average molecular speed

Text Solution

Verified by Experts

The correct Answer is:
D

Average molecular speed `= sqrt( 8 RT//pi M)`
Thus, with the increase of temperature, the average molecular speed increases. Due to this, more number of collisions of gas molecules with the walls of the container take place. This results in the increase of gas pressure.

At constnat volume for a fixed number of mole of a gas the pressure of a gas increase with rise of temperature due to .

Pressure remaining the constant, the volume of a given mass of an ideal gas increases for every degree centigrade rise in temperature by definite fraction of its volume at:

3 moles of a monoatomic gas requires occur heat for 5^(@)C rise of temperature at constant volume, then heat required for 6 moles of same gas under constant pressure for 10^(@)C rise of temperature is (R=2cal/mol-K)

For an ideal gas, number of moles per litre in terms of its pressure P, gas constant R and temperature T is

Assertion:Pressure is exerted by gas in a container with increasing temperature of the gas. Reason: With the rise in temperature, the average speed of gas molecules increases.

At constant temperature on increasing the pressure of a gas by 5% will decrease its volume by -
