Tata Steel Apprentice Interview Questions and Answers

Exothermic and endothermic reactions release and absorb heat, respectively. Heat transfer is the movement of heat from one object to another through convection, conduction, or radiation.

• Exothermic reactions release heat to the surroundings

• Endothermic reactions absorb heat from the surroundings

• Convection is heat transfer through fluid movement (e.g. boiling water)

• Conduction is heat transfer through direct contact (e.g. ...read more

There are three laws of thermodynamics.

• There are three laws of thermodynamics: the zeroth law, the first law, and the second law.

• The zeroth law states that if two systems are in thermal equilibrium with a third system, they are in thermal equilibrium with each other.

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

• The second law states that the entropy of an isolated system

Grain boundaries are interfaces between grains in a polycrystalline material, affecting material properties.

• Grain boundaries are regions where the crystal structure changes orientation.

• They can affect material properties such as strength, conductivity, and corrosion resistance.

• Grain boundaries can be classified as low-angle or high-angle boundaries based on the misorientation angle.

• Examples include the use of grain bou...read more
