Question
A gas is warmed and gains 48J of heat. The gas expands as it is heated and work is done by the system to equal 72 J. What are the values of q, w, and ∆U?
Expert Solution
Step 1
Answer : We have to calculate energy ,work and heat .
Explanation :
Since gas is warmed so system is gaining heat therefore , if system is gaining heat it will be positive .
I.e q = +48 J
Since ,work is done by the system on the surrounding .So, it will be negative
I.e w = -72 J
According to first law of thermodynamics :
dU = dq + dw
