In a closed insulated container, a liquid is stirred with a paddle to increase the temperature, which of the following is true?

Options

A. `Delta E = W = Q =0`
B. `Dleta E ne 0, Q = W = 0`
C. `Delta E= W ne 0, Q = 0`
D. `Delta E= Q ne 0, W = 0`

Answer

C

Explanation

As the system is closed and insulated no heat enters or leaves the system, i.e. q=0.
`therefore Delta E= q +W= W`
