1. Temperature- Thermometer. Thermometer is a device which is used to measure the temperature of an object. Clinical thermometer is used to measure the body temperature of humans. 2. Conduction- Solids. Conduction takes place in solids as atoms are located close together. Metals are good conductors of heat so conduction occurs through them. 3. Mica- Insulator. Mica is a good insulator. Materials which are not dense, which contain pores filled with air, act as a good insulator of heat. 4. Land hot, Sea cooler- Sea breeze. Convection current involving the flow of cold air from the sea to the land is called the sea breeze. During the daytime, hot air above the surface of the land rises up creating a low pressure area which is occupied by the cold air from the sea. 5. Bright and shiny- Poor heat absorbers. Bright and shiny colours are good reflectors of heat. They do not absorb all the radiation falling on them, so they are poor heat absorbers.
