Q. What is basic diffrence between heat and temperature?
Ans. Heat is energy which flows from hot objects to cooler ones. It flows because of the temperature difference between the objects. It always moves from warmer to cooler objects and never goes the other way.
We can detect heat flow by measuring the temperature change of an object. You can feel heat energy by sipping a hot drink. Heat flows from the coffee to your mouth and you sense that the drink is warmer than your mouth. The drink gets colder as you mouth becomes warmer. The temperature is the warm you feel sipping tea or the cold you feel with an ice cube.
