Expert Solution
Step 1) Given Data
Given 1)heat absorbed by surrounding is 4.7 MJ
2)work done on the system is 19.3 kcal Here,
Heat absorbed by surrounding
Means
Heat released by system
And heat released by system = -ve
And work done on system = +ve
So,
heat absorbed by system = Q = - 4.7 MJ
work done on the system = W = + 19.3 kcal
