Question

Match the phrase with its explanation

Column A
1. definite volume, no definite shape
2. definite volume, definite shape
3. average motion of molecules
4. internal energy transferable from a warm body to a cool one
5. energy by reason of motion

Column B
1. kinetic energy
2. solid
3. heat energy
4. liquid
5. temperature

Answer 1

Phrases from Column A are matched with their explanations in Column B; 'definite volume, no definite shape' is a liquid, 'definite volume, definite shape' is a solid, 'average motion of molecules' describes temperature, 'internal energy transferable from a warm body to a cool one' is heat energy, and 'energy by reason of motion' refers to kinetic energy.

Step-by-step explanation:

Let's match the phrases from Column A to their explanations in Column B:

Definite volume, no definite shape – This phrase describes a liquid, which takes the shape of its container but has a fixed volume.

Definite volume, definite shape – This phrase is characteristic of a solid, which maintains both a consistent volume and shape.

1. Average motion of molecules – This is referring to the concept of temperature, which indicates the average kinetic energy of the molecules in a substance.
2. Internal energy transferable from a warm body to a cool one – The term for this is heat energy, transferring thermal energy between bodies at different temperatures.
3. Energy by reason of motion – This is known as kinetic energy, which is the energy an object has due to its motion.
