Question

Transcribed Image Text:1. A rigid contained fitted with a 200 W resistive heater contains 4 Ibm of N2 (nitrogen).
Initially, the gas is at T1 = 47°C and P1 = 1.25 bar. The heater is turned on for 30 minutes.
During this time, the container is found to transfer roughly 50 kJ to its surroundings via
natural convection. The mass and volume of the heater can be neglected. Assuming the
N2 can be modelled as an ideal gas, determine:
a. T2 (°C)
b. P2 (bar)
C. Whether the ideal gas model a good approximation of the system. Show your
justification.
