Question

41. In a closed insulated container, a liquid is
stirred with a paddle to increase the
temperature. Which of the the following is
true?
1) AU =W 0,q=0 2) AU =W = 0,9 30
3) AU = 0,W = q +0 4) W = 0, AU = q = 0
please give me reply it's urgent​

Answer 1

In closed insulated container a liquid is stirred with a paddle to increase the temperature, therefore, it behaves as an adiabatic process, q=0.

Hence, from the first law of thermodynamics:

ΔE=q+W; ∵q=0

ΔE=W but not equal to zero.

Hence, the correct answer is option B.
