“The properties of matter that change with the change in temperature are calledthermal properties.”
“Heat is a form of energy transferred from one body to another as a result of a difference in temperature.”
In other words, heat is the energy that is transferred from a hotter object to a cooler object in order to equalise the temperature of both objects. Heat is different from temperature in that temperature is a measure of the average kinetic energy of the particles in a substance, while heat is a measure of the total amount of thermal energy that is transferred from one substance to another.
There are many everyday examples of heat that we experience in our daily lives. Some examples include:
| Heat | Temperature |
|---|---|
| Heat is a form of energy. | Temperature is a measure of the average kinetic energy of the particles in a substance. |
| Heat is measured in units of energy like joules or calories. | Temperature is measured in units of degrees like celsius or fahrenheit. |
| Heat is related to the amount of energy in a substance. | Temperature is related to the intensity of the energy. |
| Heat always flows from hotter objects to cooler objects. | Temperature can be the same between two objects in contact. |
Thermometer is a device used to measure temperature
A clinical thermometer is used to measure the temperature of the human body.
Thermometers have different scales to measure temperature.
There are three scales of temperature;
These three scales of temperature are interconvertible. Therefore temperature measured in Celsius scale can be converted into Kelvin and Fahrenheit scales as scale.
K =℃ +273
Conversion of temperature from Celsuis scale to Fahrenheit scale
℉ = 1.8℃ + 32
