Q2. What is heat treatment processes? Explain in brief.
Ans. 
Heat treatment processes involve heating and cooling metals to alter their properties.
• Heat treatment processes involve heating metals to specific temperatures and then cooling them at controlled rates.

• Common heat treatment processes include annealing, tempering, quenching, and normalizing.

• These processes can change the hardness, strength, toughness, and other properties of metals.

• For example, quenching involves rapid c...read more

Q3. Tell me about surface tension ?
Ans. 
Surface tension is the property of a liquid that allows it to resist an external force due to the cohesive nature of its molecules.
• Surface tension is caused by the attraction between the molecules of a liquid, which creates a 'skin' on the surface of the liquid.

• It is responsible for phenomena like capillary action, where liquids rise in narrow tubes against the force of gravity.

• Surface tension can be observed in everyd...read more

Q4. Difference between mass and weight?
Ans. 
Mass is the amount of matter in an object, while weight is the force of gravity acting on an object.
• Mass is a scalar quantity and is measured in kilograms or grams.

• Weight is a vector quantity and is measured in newtons.

• Mass remains constant regardless of location, while weight changes depending on the gravitational pull.

• For example, a person with a mass of 70 kg will have a weight of approximately 686 newtons on Earth,

Q5. Modes of heat transfer ?
Ans. 
Modes of heat transfer include conduction, convection, and radiation.
• Conduction: Heat transfer through direct contact between particles. Example: Touching a hot stove.

• Convection: Heat transfer through the movement of fluids (liquids or gases). Example: Boiling water.

• Radiation: Heat transfer through electromagnetic waves. Example: Feeling the warmth of the sun.

Q1. What is stress and strain?
Ans. 
Stress is the force applied to a material, while strain is the resulting deformation or change in shape.
• Stress is the external force acting on an object, measured in units like Newtons per square meter (N/m^2) or Pascals (Pa).

• Strain is the measure of deformation or change in shape of a material due to stress, expressed as a ratio or percentage.

• Example: When you stretch a rubber band (apply stress), it elongates (strain
