Hooke's law states that the force needed to extend or compress a spring is directly proportional to the distance it is stretched or compressed.

• Hooke's law is named after the English scientist Robert Hooke.

• It is commonly used to describe the behavior of springs and elastic materials.

• The law can be mathematically expressed as F = kx, where F is the force applied, k is the spring constant, and x is the displacement.

The second law of thermodynamics states that the entropy of an isolated system always increases over time.

• Entropy of an isolated system always increases

• Heat cannot spontaneously flow from a colder body to a hotter body

• Efficiency of a heat engine is always less than 100%

• Examples: melting ice, burning wood

Benson Boiler is a type of boiler that does not require a steam drum.

• Benson Boiler is a high-pressure, water tube boiler.

• It operates at supercritical pressure.

• The water is heated in a single pass through the evaporator tubes.

• It is commonly used in power plants.

• Examples include the Lethabo, Majuba, and Kendal power stations in South Africa.
