Problem 10P
A cylinder contains 4.0 moles of a monatomic gas at an initial temperature of 27 °C. The gas is compressed by doing 560 J of work on it, and its temperature increases by 130 °C. How much heat flows into or out of the gas?
ANSWER:
Solution 10P
Step 1 of 3
To calculate the heat flow.
The equation for change in internal energy,
Where, - Heat added up to the system
- Work done by the system
We can rewrite the change in internal energy as,
Where - Number of moles
- universal gas constant
- Change in temperature
