Problem 84GP
Suppose 1800 J of heat are added to 3.6 mol of argon gas at a constant pressure of 120 kPa. Find the change in (a) internal energy and (b) temperature for this gas. (c) Calculate the change in volume of the gas. (Assume that the argon can be treated as an ideal monatomic gas.)
ANSWER:
Step 1 of 4
Here, we have to calculate the change in internal energy of the system, temperature of the gas and the change in volume of the Argon gas.
The equation for heat at constant pressure expansion,
-----------------(1)
The equation for change in internal energy for a monoatomic gas
---------------(2)
The change in internal energy,
-------------------(3)
Where, - Number of mole of the gas
- Specific heat capacity at constant pressure
- Change in temperature
- Amount of heat added
- Universal gas constant
- Pressure
