First law of thermodynamics. Isothermal change.
The first law of thermodynamics. At constant temperature. Consider pushing the gas into the cylinder containing gas, so slowly that the temperature stays constant at temperature. This change is also known as isothermal change. As the temperature is constant delta U = 0.
0 = q + W. If you push the piston in W is positive so q is negative, and heat is lost from the cylinder.
When you push the piston out W is negative so q is positive heat enters the cylinder.
