3. Celsius scale- It is the scale used for measuring the temperature where the lower and upper points are set at $0 ° C$ and $100 ° C$ , respectively, which are the freezing and boiling points of the water.

6. Clinical thermometer- It is a type of thermometer used to measure the temperature of the human body. It is also known as the doctor's thermometer.

7. Thermometer- A device used to measure the temperature of a body is called a thermometer.

9. Convection- In this method of heat transfer, the heat gets carried away from the hotter part of the substance to the colder part by the actual movement of the mobile molecules while carrying heat along with them. This type of heat transfer occurs in fluids.

10. Mercury- It is a metal found in the liquid state at room temperature. It is used in thermometers to detect any slight change in temperature.

11. Radiation- It is a method of heat transfer that does not need any material medium. In this method, the heat is directly radiated from the source, i.e., the hot object, e.g., the sun.

1. Heat- It is a form of energy that generates the sensation of hotness and coldness. The natural source of heat is the sun.

2. Temperature- It is the measure of the degree of how much hot or cold a body is.

4. Land breeze- At night, when the wind blows from the land to the sea is called a land breeze.

5. Laboratory thermometer- It measures the temperature in the range of $- 10 ° C t o 110 ° C$ .

6. Conduction- The process of heat transfer from the hotter part to the colder part of the object through the vibration of particles on their mean positions is called conduction. This type of heat transfer takes place between solids.

8. Insulators- The materials which do not allow to pass the heat through them are called bad conductors of heat or insulators.
