Q2. What is humidity
Ans. 
Humidity is the amount of water vapor present in the air.
• Humidity is typically measured as a percentage.

• High humidity can make the air feel warmer than it actually is.

• Low humidity can lead to dry skin and respiratory issues.

• Humidity levels can affect the growth of mold and bacteria.

• Examples: 50% humidity means the air is holding half of the maximum amount of water vapor it can hold at that temperature.

• Examples: A humid...read more

Q3. What is entropy
Ans. 
Entropy is a measure of disorder or randomness in a system.
• Entropy is a thermodynamic property that describes the amount of energy in a physical system that is not available to do work.

• It is a measure of the number of possible arrangements the particles in a system can have.

• Entropy tends to increase in closed systems over time, leading to a state of maximum disorder or equilibrium.

• An example of entropy is the melting o...read more

Q4. What is enthalpy
Ans. 
Enthalpy is a thermodynamic property that represents the total heat content of a system.
• Enthalpy is denoted by the symbol H and is defined as the sum of the internal energy of a system plus the product of pressure and volume.

• It is often used in thermodynamics to analyze energy changes in chemical reactions or phase transitions.

• Enthalpy can be expressed as H = U + PV, where U is the internal energy, P is the pressure, a...read more

Q5. What is thermodynamics
Ans. 
Thermodynamics is the branch of physics that deals with the relationships between heat and other forms of energy.
• It studies the transfer of energy in the form of heat and work.

• It involves concepts like temperature, pressure, and entropy.

• Thermodynamics laws include the first law (conservation of energy) and the second law (entropy always increases).
