If heat leaves a substance, it becomes colder (temperature falls) and when heat enters it becomes warmer (temperature climbs). Note that, because of entropy, heat will only go from warm to cold things.

What is the reason for heat transfer from one substance to another?

Heat transfer occurs from one substance to another in order to equalize their temperatures. This process happens because of the natural tendency of heat to move from areas of higher temperature to areas of lower temperature until thermal equilibrium is reached.


What happens to the thermal energy of a substance as its temperature increases?

As the temperature of a substance increases, its thermal energy also increases. This leads to greater kinetic energy of the particles within the substance, causing them to move faster and creating more thermal energy.


What happens when energy is transferred from one system to another?

When energy is transferred from one system to another, it can result in changes in the motion, temperature, or other properties of the receiving system. This transfer can occur through processes such as conduction, convection, or radiation, and the energy can be converted from one form to another during the transfer.


What happens to temperature if the average motion of particles is increased?

If the average motion of particles is increased, the temperature of the substance will also increase. This is because temperature is directly related to the average kinetic energy of the particles in a substance. As particles move faster, they have more kinetic energy and thus the temperature rises.


What happens to viscosity as temperature increases?

As the temperature rises, the viscosity, meaning a substance's resistance to flow decreases because a liquid based substance melts, and flows more.Viscosity decreases as temperature increases.

What happens to the particles in something if the temperature falls?

When the temperature falls, the particles in a substance slow down and lose energy. This can cause the substance to contract or solidify, depending on the type of material and how much the temperature decreases.
