The laws of thermodynamics describe the behavior of energy in physical systems.

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

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

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

• Stree is a Bollywood movie released in 2018.

• It is a horror comedy film directed by Amar Kaushik.

• The movie is based on the Indian urban legend of Nale Ba, a witch who knocks on people's doors at night.

Annealing is a heat treatment process used to alter the properties of materials, making them more ductile and less brittle.

• Annealing involves heating a material to a specific temperature and then cooling it slowly.

• The process relieves internal stresses, improves machinability, and enhances electrical conductivity.

• Examples of annealing include the heat treatment of steel to reduce hardness and increase toughness, and th...read more

Bulk modulus is a measure of a substance's resistance to compression under applied pressure.

• Bulk modulus is a property of materials that describes their compressibility.

• It measures the change in volume of a substance when subjected to a change in pressure.

• It is defined as the ratio of the change in pressure to the fractional change in volume.

• The higher the bulk modulus, the less compressible the material is.

• For example...read more

The instantaneous centre is a point in a mechanism or system that has zero velocity at a given instant.

• The instantaneous centre is also known as the instantaneous axis of rotation.

• It is the point around which all other points in the system have zero velocity.

• In a rotating system, the instantaneous centre can change as the system moves.

• The concept of instantaneous centre is used in kinematics and dynamics to analyze the...read more
