Do all materials transfer heat equally
WebFeb 1, 2024 · That heat came from the piece of rebar, which initially was at a higher temperature. Assuming that all heat transfer was between the rebar and the water, with no heat “lost” to the surroundings, then heat given off by rebar = −heat taken in by water, or: \[q_\ce{rebar}=−q_\ce{water} \label{5.3.3}\] WebMay 13, 2024 · The transfer of heat goes from the hot object to the cold object. We can imagine a system, however, in which the heat is instead transferred from the cold object to the hot object, and such a system does not violate the first law of thermodynamics. The cold object gets colder and the hot object gets hotter, but energy is conserved.

WebBut it is quite easy to do a separate experiment to determine the total heat capacity of the calorimeter. You often set up your calculations like this: heat for water + heat for object + heat for calorimeter = 0. q₁ + q₂ + q₃ = 0. q₁ = m₁s₁ΔT₁ for the water. q₂ = m₂s₂ΔT₂ for the object. q₃ = CΔT for the calorimeter.
