Q2. What is 3rd Law of thermodynamics?
Ans. 
The 3rd Law of thermodynamics states that the entropy of a perfect crystal at absolute zero is zero.
• The 3rd Law of thermodynamics states that as the temperature of a system approaches absolute zero, the entropy of the system also approaches zero.

• It is impossible to reach absolute zero in practice, but this law helps in understanding the behavior of systems at extremely low temperatures.

• This law is important in the stud...read more

Q1. What is the mode of heat transfer.
Ans. 
The mode of heat transfer refers to the way heat is transferred from one object to another.
• Conduction: Heat transfer through direct contact between particles (e.g. touching a hot pan)

• Convection: Heat transfer through the movement of fluids or gases (e.g. boiling water)

• Radiation: Heat transfer through electromagnetic waves (e.g. feeling the warmth of the sun)

• Examples: Cooking food on a stove (conduction), heating a room...read more

Q2. What is the pump efficiency.
Ans. 
Pump efficiency is a measure of how well a pump converts input power into useful work output.
• Pump efficiency is calculated by dividing the pump's output power by its input power.

• Efficiency is usually expressed as a percentage, with higher percentages indicating better efficiency.

• Factors that can affect pump efficiency include design, operating conditions, and maintenance.

• For example, a pump with an efficiency of 80% wo...read more
