Problem 8.9 6th edition

Postby ChathuriGunasekera1D » Mon Jan 28, 2019 1:11 pm

Hi! I'm having trouble starting this problem off. Any help is appreciated!

An ideal gas in a cylinder was placed in a heater and gained 5.50 kJ of energy as heat. If the cylinder increased in volume from 345 mL to 1846 mL against an atmospheric pressure of 750. Torr during this process, what is the change in internal energy of the gas in the cylinder?

find the value of work by using the equation w=-Pressure * change in the volume. then to get deltaU, take q (given in the problem) and add it with work
