What tells us how much heat the object has?

🌡Temperature tells us the degree of hotness or coldness of an object.

🌡It is a measurable physical property like other measurable physical properties such as velocity, mass, and density.

🔬At a microscopic level, temperature describes the average kinetic energy of molecules within a material or system.

🌡Temperature is typically seen in units of degrees Celsius or °C (in some countries the Fahrenheit scale is used).

🌡Celsius is the standard unit of temperature in the metric system of units. Celsius is split up into degrees, with one degree being 1/100 of the temperature difference between the boiling and freezing points of water.

🌡Fahrenheit is equal to 9/5 degrees Celsius.

🌡Scientists use the Kelvin scale, which doesn’t measure temperature in degrees. Zero Kelvin is ‘absolute zero’, the coldest temperature and lowest energy level equal to about -273 degrees °C.

🌡A thermometer is a device used for measuring temperature.
