OK, this is pretty interesting.
First get out your parameters.
Pressure of gas, P= 1.5×10^5 Pa
Initial volume, V1=0.0002m³
Final volume, V2=0.0006m³
Heat change, ∆H= +32J (it is positive since it was absorbed.)
Now you can solve.
∆U= ∆H—P∆V
∆U=32J—(1.5×10^5×(0.0006—0.0002))
∆U=32J—(1.5×10^5×0.0004)
∆U=32J—(1.5×10^5×4×10^—4)
∆U=32—60
∆U=—28J
That corresponds to option C.
Conserved
Explanation:
The first law of thermodynamics states that energy in a systems is "conserved".
This law is the law of conservation of energy of energy. It states that:
"in an isolated system, energy can neither be created nor destroyed but it is transformed from one form to another".
- This simply shows that energy is conserved in an isolated system.
- In an isolated system, there is no exchange of energy with the environment.
- Also, energy is neither formed nor destroyed but transformed.
