Question
Chapter 9, Problem 1SC
Interpretation Introduction
Interpretation:
When ice is put in a glass of water, the water cools down. This indicates that water has lost some of its thermal energy. The factor responsible for this process is to be identified.
Concept introduction:
Thermal energy is the form of energy that is possessed by an object due to the movement of particles within the object. Thermal energy is a kind of internal energy that arises due to the kinetic energy of atoms and molecules. It is related to the temperature. Heat is transferred between two objects as they both have a difference of temperature.
