Match the following : 1. Heat a. Kelvin 2. Temperature b. Conductor 3. Conduction c. Solids 4. Glass d. Insulators 5. Metal e. Joule

1 - e Heat is a form of energy, and it is measured in joules. Heat flows from one body to another due to temperature difference. 2 - a The SI unit of temperature is kelvin. It is also measured in degree centigrade. Temperature of a body can be increased by supplying heat energy to a body. 3 - c In solids, heat is transferred through conduction. In solids, molecules are closely packed. Due to this, conduction is possible in solids. 4 - d Glass is an insulator through which heat cannot be transferred. Other examples of insulators are rubber, wood, etc. The insulators are also called as bad conductors of heat. 5 - b Metals are good conductors of heat and electric current. The heat is transferred in metals through conduction. 1. Heat e. Joule 2. Temperature a. Kelvin 3. Conduction c. Solids 4. Glass d. Insulators 5. Metals b. Conductor
