Q1. What is Heat Transfer
Ans. 
Heat transfer is the process of energy moving from a warmer object to a cooler object.
• Heat transfer can occur through conduction, convection, or radiation.

• Conduction is the transfer of heat through direct contact, like a metal spoon getting hot in a pot of soup.

• Convection is the transfer of heat through the movement of fluids, like boiling water in a pot.

• Radiation is the transfer of heat through electromagnetic waves, ...read more

Q2. How distillation column works
Ans. 
Distillation column separates components of a liquid mixture based on differences in boiling points.
• Works on the principle of vapor-liquid equilibrium

• Liquid mixture is heated to create vapor, which rises through column

• Vapor condenses at different heights based on boiling points, separating components

• Components are collected at different points of the column

• Commonly used in oil refineries to separate crude oil into diff...read more

Q2. What is Law of motion
Ans. 
Law of motion is a fundamental concept in physics that describes the behavior of objects in motion.
• There are three laws of motion formulated by Sir Isaac Newton.

• The first law states that an object at rest will remain at rest, and an object in motion will remain in motion with a constant velocity, unless acted upon by a net external force.

• The second law states that the acceleration of an object is directly proportional ...read more
