Answer to Question #215700 in Physical Chemistry for shreya goyal

Question

An engine containing 2 kg air as working substance is initially at 1 atm and 27 0C.

The system undergoes isochoric process to a point where pressure of the system is 2

atm. At this point heat is transferred to the air untill the volume doubles. Calulate

the total workdone and the amount of heat transferred to the air.

Answer 1

To calculate the amount of heat released in a chemical reaction, use the equation Q = mc ΔT, where Q is the heat energy transferred (in joules), m is the mass of the liquid being heated (in kilograms), c is the specific heat capacity of the liquid (joule per kilogram degrees Celsius), and ΔT is the change.
