Webb5 nov. 2024 · 1.S: Temperature and Heat (Summary) Thumbnail: Natural convection plays an important role in heat transfer inside this pot of water. Once conducted to the inside, heat transfer to other parts of the pot is mostly by convection. The hotter water expands, decreases in density, and rises to transfer heat to other regions of the water, while colder … Webb28 dec. 2024 · Temperature Changes and Phase Changes. The formula that relates the change in temperature to an object’s mass, specific heat capacity and heat energy added or removed is as follows: Q = mc\Delta T Q = mcΔT. This formula only applies, however, if the substance is not undergoing a phase change.
