A system is given 300 calories of heat and it does 600 joules of work. How much does the internal energy of the system change in this process `(J=4.18 "joules"//cal)`

A

654 joule

B

156.5 joule

C

- 300 joule

D

- 528.2 joule

Text Solution

Verified by Experts

The correct Answer is:
A
`Delta Q=Delta U+Delta W`
`implies Delta U=4.18xx300-600=654 J`.
