On completion of this lesson, students should be able to:
Heat is a form of energy that gives sensation of warmth. The SI unit of heat is joule. This note provides short introduction about heat and temperature scale.
Heat equation is Q = msdt where, S is proportionality constant and is known as specific heat capacity. This note details about heat equation and specific heat capacity along with principle of calorimetry.
When water is heated from 0 degree Celsius to 4 degree Celsius, its volume decreases and increases only after 4 degree Celsius. This unusual behavior of water from 0 degree Celsius to 4 degree Celsius is known as anomalous expansion of water. This note has detail explanation of anomalous behavior of water when it is heated to 4 degree centigrade.
Temperature is the thermal condition of a body which determines the flow of heat from the body to another body on its contact. It is the average kinetic energy of the molecules contained in the body.
