Internal enggy of system increases when

by 400 I

System absorbes heat of 30 cal. Calculate work done on/by the system.​

Answer 1

Answer:

Use 1st law of thermodyanamics

Explanation:

Internal energy(dU)=400

Dq= -30 as it absorbs its negative if it emits its positive

dW=dU+dQ

=400-30

=370 cal. for joules multiply with 4.2
