Thermodynamics

31.

The general gas energy equation is (where Q_{1 - 2} = Heat supplied, dU = Change in internal energy, and W_{1 - 2} = Work done in heat units)

Q_{1 - 2} = dU + W_{1 - 2}

Q_{1 - 2} = dU - W_{1 - 2}

Q_{1 - 2} = dU/W_{1 - 2}

Q_{1 - 2} = dU x W_{1 - 2}

Based on 1st law of thermodynamics that's energy conservation. DQ = W + DU.

Work done on system W is -ve hence A will be the right option.

Aravind said: 8 years ago

No, answer is option B. Because, dU= dQ+dW according to 1st law of thermodynamics.
