Q1. What is Hardness
Ans. 
Hardness is a measure of a material's resistance to deformation or scratching.
• Hardness is often measured using the Mohs scale for minerals or the Rockwell scale for metals.

• Materials with higher hardness values are more resistant to wear and abrasion.

• Hardness can also affect a material's machinability and ability to be shaped or formed.

• Common examples of hard materials include diamond, steel, and ceramics.

Q2. What is yield point
Ans. 
Yield point is the stress at which a material begins to deform plastically.
• Yield point is the point on a stress-strain curve where the material transitions from elastic to plastic deformation.

• It is an important property in materials science and engineering as it indicates the maximum stress a material can withstand without permanent deformation.

• Yield point is typically determined through tensile testing of materials.

Q2. Define Entropy with example
Ans. 
Entropy is a measure of disorder or randomness in a system.
• Entropy is a concept in thermodynamics that quantifies the degree of randomness or disorder in a system.

• It is a measure of the number of possible arrangements or states that a system can have.

• Entropy increases with the increase in randomness or disorder.

• For example, a deck of cards in perfect order has low entropy, but shuffling the deck increases the entropy.

Q3. Basic laws of thermodynamics
Ans. 
The basic laws of thermodynamics govern the behavior of energy in various systems.
• The first law of thermodynamics, also known as the law of energy conservation, states that energy cannot be created or destroyed, only transferred or transformed.

• 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 approache...read more

Q4. Define thermodynamics equilibrium
Ans. 
Thermodynamic equilibrium is a state where there is no net change in the macroscopic properties of a system over time.
• Thermodynamic equilibrium is a stable state where all forces and processes within a system are balanced.

• In thermodynamic equilibrium, the system is at a uniform temperature and pressure throughout.

• There is no transfer of heat or work between the system and its surroundings in thermodynamic equilibrium.

• E...read more
