Q3. Explain modes of Heat Transfer
Ans. 
Heat can be transferred through conduction, convection, and radiation.
• Conduction: Heat transfer through direct contact between objects or substances.

• Convection: Heat transfer through the movement of fluids or gases.

• Radiation: Heat transfer through electromagnetic waves, without the need for a medium.

• Examples: Touching a hot pan (conduction), boiling water (convection), feeling the warmth of the sun (radiation).

Q2. What is enthalphy?
Ans. 
Enthalpy is a thermodynamic property that represents the total energy of a system, including internal energy and the amount of energy required to create or release the system.
• Enthalpy is denoted by the symbol H and is expressed in units of energy (such as Joules or calories).

• It is defined as H = U + PV, where U is the internal energy of the system, P is the pressure, and V is the volume.

• Enthalpy change (ΔH) is commonly...read more
