Question

A piston is used to compress a gas from 1.0 atm to 3.5 atm. If the volume change
from 1.5 L to 0.75 L, what is the final temperature, if it started at 300 K?
A) 105b0 K
B) 700K
C) 525 K
D) 300 K​

Answer 1

Answer:

Heat Capacity at Constant Volume

For an ideal gas, applying the First Law of Thermodynamics tells us that heat is also equal to: Q = ΔEint + W, although W = 0 at constant volume. This is from the extra 2 or 3 contributions to the internal energy from rotations.
