Question

if the amount of heat required to raise temperature of 2 moles monoatomic ideal gas by 1 degree celsius at constant pressure is 10 cal , then change in internal energy of gas is(R=2cal/k-mol


answer it pls

Answer 1

Answer:

Q = ( n ) ( Cvm ) ( T2 - T1 )

For a monataomic ideal gas :

Cvm = ( 3/2 ) ( R ) = ( 3/2 ) ( 8.313 J/mol - K ) = 12.47 J/mol - K

Q = ( 2 mol ) ( 12.47 J/mol - K ) ( 10 C )

Q = 249 J <-------------------
