Q1. What is thermal expansion .
Ans. 
Thermal expansion is the tendency of matter to change in shape, area, and volume in response to a change in temperature.
• Thermal expansion occurs when a material expands or contracts due to a change in temperature.

• Most materials expand when heated and contract when cooled.

• This phenomenon is utilized in various applications such as in the design of bridges, railways, and pipelines to account for temperature changes.

Q2. What is density.
Ans. 
Density is a measure of how much mass is contained in a given volume.
• Density is calculated by dividing the mass of an object by its volume.

• It is typically measured in units such as grams per cubic centimeter or kilograms per liter.

• Objects with higher density will sink in fluids with lower density, and vice versa.

• For example, gold has a higher density than water, so it sinks in water.

Q3. What is surface tension.
Ans. 
Surface tension is the tendency of liquid molecules to stick together at the surface, creating a 'skin' that resists external forces.
• Surface tension is caused by the cohesive forces between liquid molecules.

• It results in the formation of droplets and the ability of certain insects to walk on water.

• Surface tension can be reduced by adding surfactants or by increasing temperature.

• It is measured in units of force per unit...read more
