Text Solution

Verified by Experts

The correct Answer is:
A
Using
`DeltaU=nC_(v)xxDeltaT`
`DeltaT=100" "n=3.5`
`C_(V)=2xx10^(-2)`
`DeltaU=7`.

Molar heat capacity of a gas at constant volume.

A gas of volume changes 2 litre to 10 litre at constant temperature 300K, then the change in internal energy will be :

One mole of a gas absorbs 200 J of heat at constant volume. Its temperature rises from 298 K to 308 K. The change in internal energy is :-

The constant volume molar heat capacity of an ideal gas is expressed by C_(v, m) = 16.5 +10^(-2)T (All values are in SI units). If 2.5 mol of this gsa at constant value is heated from 27^(@)C ro 127^(@)C , the internal energy increases by ''x'' kJ. Hence, x is

Molar heat capacity of gas whose molar heat capacity at constant volume is C_V , for process P = 2e^(2V) is :

When two mole of an ideal gas (C​_(p.m.) = 5/2R) heated from 300K to 600K at constant volume. The change in entropy of gas will be :-

A system absorbs 100J of heat at constant volume and its temperature raises from 300K to 320K. Calculate the change in internal energy.

The molar heat capacity of a gas at constant volumes is C_V . If n moles of the gas under DeltaT change in temperature it's internal energy will change by nC_VDeltaT
