Question

50 R calories of heat is required to
raise the temperature of 4 moles of an
ideal gas at constant pressure from
50°C to 55°C. The gas may be:
1) N2
2) CO3
3) He
4) CH4​

Answer 1

Answer:

answer is helium.

Explanation:

dU = n.CpdT.

50R= 4*Cp*(55-50)

50R= 4*5*Cp

(50/20)R= Cp

thus , Cp is obtained as (5/2)R

this shows that the gas is a monoatomic gas.

hope this helps.......
