The process where liquid substances turn into vapor is called evaporation.

The temperature in which water can theoretically remain in all three states is called absolute zero temperature. -273 degrees Celsius or 0 K is known as absolute zero temperature.

The coefficient of linear expansion is the change in length of by one unit long when its temperature is changed by one degree.

The degree or intensity of heat present in a substance or object, especially as expressed according to a comparative scale and down by a thermometer or perceived by touch.

If a body is immersed in a liquid, the weight of the body is reduced by an amount equal to the displaced liquid. If an object is partially or completely submerged in a stagnant liquid or gaseous matter then the object seems to have lost a bit of weight. This lost weight is equal to … Read more

At standard pressure, the temperature at which ice starts to melt is called ice point.

The characteristic of musical sound by which the sound of the same intensity is sometimes heard dull and sometimes sharp is called pitch of sound.

To define a temperature scale, two reference temperatures are chosen, these two temperatures are called the fixed points.
