Heat transfer occurs through conduction, convection, and radiation.

• Conduction is the transfer of heat through a material without any movement of the material itself.

• Convection is the transfer of heat through the movement of fluids or gases.

• Radiation is the transfer of heat through electromagnetic waves.

• Examples include touching a hot stove (conduction), boiling water (convection), and feeling the warmth of the sun (rad

The laws of thermodynamics describe the behavior of energy in a system. Entropy always increases in a closed system.

• The first law states that energy cannot be created or destroyed, only transferred or converted.

• The second law states that the total entropy of a closed system always increases over time.

• The third law states that as temperature approaches absolute zero, the entropy of a system approaches a minimum.

• Entropy ...read more

The engine works by converting fuel into energy through combustion, which powers the pistons and turns the crankshaft.

• Fuel is mixed with air and ignited in the combustion chamber

• The resulting explosion pushes the piston down, which turns the crankshaft

• The crankshaft converts the linear motion of the piston into rotational motion

• The rotational motion is transferred to the wheels through the transmission

• Examples of engin
