Did you know that there are only two (2) ways to increase a body’s temperature? Indeed, there are only two ways to increase a body’s temperature. One is with work, the other is with heat.
To repeat: There are only two ways to increase a body’s temperature, and the first is with work being done on the body, and the second is with heat being sent to the body. The 1st Law of Thermodynamics captures this. This is all of the 1st Law! All of it. And it is written as
dU = dQ – dW,
where dU is the change in internal energy of a system, dQ is the heat entering the system, and dW the work done by the system.
Next, if we refer to the definition of heat
“Heat is defined as any spontaneous flow of energy from one object to another caused by a…
