Define temperature
define absolute zero

Temperature is a measure of the average energy of molecular motion in a substance. In everyday usage, temperature indicates a measure of how hot or cold an object is. Temperature is an important parameter in chemistry. When a substance changes from solid to liquid, it is because there was in increase in the temperature of the material. Chemical reactions usually proceed faster if the temperature is increased.

Absolute zero is the lowest temperature in Kelvin which all motion stops. Absolute zero is called 0 Kelvin (0 K), and it is equivalent to –273.15°C or –459.67°F.

Temperature:

The degree of hotness or coolness is expressed by temperature, which is a physical property. When a body comes into touch with another that is colder or hotter, it is the manifestation of thermal energy, which is present in all matter and is the cause of the occurrence of heat, a flow of energy.

Absolute zero:

Absolute zero is the lowest point on the thermodynamic temperature scale, the point at which the enthalpy and entropy of a cooled ideal gas are equal to 0 kelvins.
