The Matter is defined as any substance that has mass and occupies space. Temperature is one of the physical properties of matter. The temperature of the matter defines the state of it. Also, there are other temperature-related properties of matter like thermal conductivity, thermal diffusivity and so on. We all have common sense notions of heat and temperature. Temperature is a measure of ‘hotness’ of a body. A measure of temperature is obtained using a thermometer. Liquid-in-glass thermometers show different readings for temperatures other than the fixed points because of differing expansion properties.
