Q1. What is distillation
Ans. 
Distillation is a process used to separate components of a liquid mixture based on their different boiling points.
• Distillation involves heating a liquid mixture to create vapor, then cooling the vapor to condense it back into liquid form.

• The components with lower boiling points will vaporize first and be collected, leaving behind components with higher boiling points.

• Examples of distillation include the separation of a...read more

Q2. Mode of heat transfer
Ans. 
Heat transfer can occur through conduction, convection, or radiation.
• Conduction: Heat transfer through direct contact between particles, such as a metal spoon heating up in a hot drink.

• Convection: Heat transfer through the movement of fluids or gases, like boiling water in a pot.

• Radiation: Heat transfer through electromagnetic waves, like the sun warming the Earth.
