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. The calorie, which is not a metric unit, is defined as the energy needed to raise the temperature of one gram of water by one degree C. The energy needed to raise the temperature of one gram of something other tha...
