Explain the difference between heat and temperature?
Heat and temperature are related concepts, but they have distinct meanings.
Heat refers to the transfer of thermal energy between two objects or systems. It is the energy that flows from a hotter object to a cooler one, and it occurs when there is a temperature difference between them. Heat is measured in units such as calories or joules.
Temperature, on the other hand, is a measure of the average kinetic energy of the particles within an object or substance. It represents the degree of hotness or coldness of an object and can be measured using various temperature scales (e.g., Celsius, Fahrenheit, Kelvin). Temperature is a scalar quantity and is usually measured using a thermometer.
In summary, heat is the energy transferred due to temperature differences, while temperature is a measure of the average kinetic energy of the particles within an object. Heat can cause a change in temperature, but they are separate concepts.
