Q2. What is the process of cooling in AC
Ans. 
AC cooling process involves refrigerant absorbing heat from indoor air and releasing it outside.
• Refrigerant absorbs heat from indoor air through evaporator coils

• The warm refrigerant is then pumped to the condenser coils located outside

• Condenser coils release the heat absorbed from indoor air to the outside environment

• The refrigerant then goes back to the evaporator coils to repeat the cycle

Q4. What is piston, crank shaft, bearing
Ans. 
A piston is a component in an engine that moves up and down in a cylinder, converting pressure into mechanical motion. A crankshaft is a rotating shaft that converts reciprocating motion into rotational motion. A bearing is a device that supports and reduces friction between moving parts.
• Piston: Moves up and down in a cylinder, sealed by piston rings. Transfers force from expanding gases to the crankshaft.

• Crankshaft: C...read more
