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 between materials, like a metal spoon heating up in hot 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 electromagn...read more

Q2. What 2 law of thermodynamics tell us?
Ans. 
The two laws of thermodynamics are the first law, which states that energy cannot be created or destroyed, only transferred or converted, and the second law, which states that the entropy of an isolated system always increases over time.
• First law of thermodynamics: Energy cannot be created or destroyed, only transferred or converted.

• Second law of thermodynamics: The entropy of an isolated system always increases over t...read more

Q1. What is boiling and melting point in exact word?
Ans. 
Boiling point is the temperature at which a liquid turns into a gas, while melting point is the temperature at which a solid turns into a liquid.
• Boiling point is dependent on atmospheric pressure.

• Melting point is dependent on the substance's intermolecular forces.

• Water boils at 100°C and melts at 0°C at standard pressure.

• Different substances have different boiling and melting points.

• Boiling and melting points can be us
