Problem 20P
IP If 8.00 moles of a monatomic ideal gas at a temperature of 245 K are expanded isothermally from a volume of 1.12 L to a volume of 4.33 T, calculate (a) the work done and (b) the heat flow into or out of the gas. (c) If the number of moles is doubled, by what factors do your answers to parts (a) and (b) change? Explain.
ANSWER:
Step 1 of 4
To calculate the work done and heat flow if an ideal gas is expanded isothermally.
Equation for work done in isothermal process is,
Where, - Number of moles of the gas
- Universal gas constant
- Temperature
and are initial and final volumes.
