Jun 6, 2015 · In the modern way of viewing things, no, (rest) mass is invariant. What happens is that the energy content of the body changes and some people still interpret this as a change in mass (which is an old point of view that, unfortunately, is fairly common). A nice discussion about this can be found here:
Temperature: When a substance is heated, its particles gain kinetic energy, which causes them to vibrate more vigorously and move further apart. If enough energy is absorbed, the particles can overcome the forces holding them together, leading to a phase change.
Aug 20, 2020 · where \(q\) is heat, \(m\) is mass, \(C_s\) is the specific heat, and \(ΔT\) is the temperature change. Eventually, the temperatures of the two substances will become equal at a value somewhere between their initial temperatures.
The quantitative relationship between heat transfer and temperature change contains all three factors: Q = mcΔT, where Q is the symbol for heat transfer, m is the mass of the substance, and ΔT is the change in temperature. The symbol c stands for specific heat and depends on the material and phase.
Oct 11, 2023 · The mass of ice is about 7% of the mass of the soda but leads to a noticeable change in the temperature of the soda. Although we assumed that the ice was at the freezing temperature, this is unrealistic for ice straight out of a freezer: The typical temperature is \(-6^oC\).
Oct 8, 2020 · The main factors that cause phase changes are changes in temperature and pressure. At the phase transition, such as the boiling point between liquid and gas phases, the two states of matter have identical free energies and are equally likely to exist.

Therefore, to calculate the specific heat capacity of the substance in any form, divide the heat added to the substance by the mass of the substance times the temperature change of the substance. For the phase change diagram shown in Figure 17.2, in the solid phase, 50 cal of heat increases the temperature from -200 o C to -100 o C, a ...
