   These different colours of light have different wavelengths and frequencies. Red light has the longest wavelength, and the lowest frequency of the visible spectrum. Violet has the shortest wavelength, and the highest frequency of the visible spectrum.

   Mixing coloured materials, such as paint, is an example of subtractive colour mixing. Red paint appears red to us because when white light strikes it, the red pigments reflect the red wavelengths of light and absorball of the wavelengths. This reflected light is what is seen by our eyes. The same is true for all of the other colours. So what about ...

   Experiments show that the heat transferred to or from a substance depends on three factors—the change in the substance’s temperature, the mass of the substance, and certain physical properties related to the phase of the substance. The equation for heat transfer Q is. Q = mcΔT, Q = m c Δ T, 11.7.

8. People also ask

   What is the relationship between heat transfer and temperature change?

   • A practical approximation for the relationship between heat transfer and temperature change is: Q = mcΔT, where Q is the symbol for heat transfer (“quantity of heat”), m is the mass of the substance, and ΔT is the change in temperature.

   What is heat transfer in chemistry?

   • The motion of molecules and atoms is responsible for heat or thermal energy and every matter has this thermal energy. The more the motion of molecules, more will be the heat energy. However, talking about heat transfer, it is nothing but the process of transfer of heat from a high-temperature body to a low temperature one. What is Heat Transfer?

   Why is heat a type of energy transfer?

   • Heat is a type of energy transfer that is caused by a temperature difference, and it can change the temperature of an object. As we learned earlier in this chapter, heat transfer is the movement of energy from one place or material to another as a result of a difference in temperature.

   What is the equation for heat transfer?

   • The equation for heat transfer Q is where m is the mass of the substance and Δ T is the change in its temperature, in units of Celsius or Kelvin. The symbol c stands for specific heat, and depends on the material and phase. The specific heat is the amount of heat necessary to change the temperature of 1.00 kg of mass by 1.00 ºC.

   How does heat transfer occur?

   • Heat transfer occurs when thermal energy moves from one place to another. Atoms and molecules inherently have kinetic and thermal energy, so all matter participates in heat transfer. There are three main types of heat transfer, plus other processes that move energy from high temperature to low temperature.
