Transcribed Image Text:An ideal gas is heated from 25.0°C to 335°C under a constant pressure of 2.81 kPa.
i.
If its initial volumeis 1.45m?, what is its final volume?
ii.
If the change in internal energy is 5.84kJ, how much heat is added to the gas?
Assume any kinetic and potential energies are negligible.
ii.
What type of a process is this?
Given:
• Energy balance on a closed system at steady state AU + AE + AE, = Q – W,
where U stands for internal energy, E for kinetic energy, E, for potential energy, Q
for heat flow and W for work done by the system.
PV = nRT, R = 8.314 = 8.314:
T(K) = T(°C) + 273.15; 1N = 1 m: 1 Pa = 1.
