The mass of an entity will remain constant, independent of temperature. It is always the volume that changes. Take water for example:
When you have measure 1kg of liquid water in a closed container of dimensions 1m x 1m x 1m (it is closed so no water will evaporate), its mass will remain 1kg whether the room is 7°C or 45°C. As the volume of the container is 1m3, the density of the measured water is 1kg.m-3.
[Density is mass / volume]
Now assume the water is frozen (below 0°C), its volume will increase due to its expansion. As the density of ice is less that of water, the ice will float (hence why we get icebergs in the sea). The mass however will remain the same as nothing has been added or taken away.
N.B - water is at its most dense at 4°C.
It increases temperature of the matter leading to melting, boiling and subsequent vaporization of the matter.
Predominant examples are pressure and temeperature.
Basically, matter can expand or contract due to changes in temperature, or in pressure.

If heat leaves matter, one of two things will happen:* The temperature decreases, or * There is a change in phase - for example, from liquid to solid.
Temperature.
Temperature change is not a chemical change.
Temperature.
How did temperature affect the cookie dough? Was any matter lost during baking?
It can.
Pressure and temperature are two factors that both affect the state of any type of matter.
The radius will not change because a white dwarf is made of electron degenerate matter, so temperature does not affect pressure or volume.
Assuming that pressure and the amount of matter are constant (meaning they do not change), volume will increase as temperature increases.

Examples of chemical changes of matter include, but are not limited to: color change, formation of a precipitate, formation of a gas, change in energy.
It increases temperature of the matter leading to melting, boiling and subsequent vaporization of the matter.
