How heat is measured

In general, steady-state techniques perform a measurement when the temperature of the material measured does not change with time. This makes the signal analysis straightforward (steady state implies constant signals). The disadvantage is that a well-engineered experimental setup is usually needed. Steady-state methods, in general, work by applying a known heat flux, , to a sample with a surfa… WebAnswer (1 of 4): The video might have confused you in that it is only about water.
