Heat is a form of energy that transfers from one body to another body, which are at different temperatures. It generally flows from a body of high temperature to a body of low temperature. For example if you place an ice cube near any hot substance, since heat transfers from ... Read More

Time is the indefinite continued progress of events that occur in apparently irreversible succession from the past, through the present, into the future.

A conductor is a substance through which heat transfers very quickly. Most of the metals are good conductors of heat. For example, Copper, iron, aluminum, etc are good conductors of heat. Whereas, an insulator is a substance through which heat transfers very slowly. For example, wood, plastic, glass, etc are ... Read More
