Question 19
XE-ENAT2 marksNeeds review
A frictionless piston cylinder device contains 1 kg of an ideal gas. The gas is compressed according to Pv¹·³ = constant (P is pressure and v is mass specific volume), from 100 kPa, 250 K, till it reaches a temperature of 500 K. The heat transfer from the piston cylinder device to its surroundings is __________ kJ (2 decimal places).
The characteristic gas constant is 287 J/(kg K) and the ratio of specific heat capacities is 1.4.
