Question

need help with heat engines

Answer 1

In thermodynamics, a heat engine is a system that performs the conversion of heat or thermal energy to mechanical work.It does this by bringing a working substance from a high temperature state to a lower temperature state. A heat "source" generates thermal energy that brings the working substance to the high temperature state. The working substance generates work in the "working body" of the engine while transferring heat to the colder "sink" until it reaches a low temperature state. During this process some of the thermal energy is converted into work by exploiting the properties of the working substance. The working substance can be any system with a non-zero heat capacity, but it usually is a gas or liquid.

Answer 2

hey how we get Internal energy=3/2 n k t

Answer 3

?

Answer 4

u thr?

Answer 5

PV=\[uRT\]
E=N*1/2MV^2
N IS THE NO. OF MOLECULES
PV=2/3E
E=3/2PV
E=3/2kNT
