Q2. What is enthalpy and entropy
Ans. 
Enthalpy is the heat content of a system while entropy is the measure of disorder or randomness in a system.
• Enthalpy is the sum of internal energy and the product of pressure and volume.

• Entropy is a measure of the number of possible arrangements of a system.

• Enthalpy is used in thermodynamics to describe heat transfer in chemical reactions.

• Entropy is used to predict the direction of chemical reactions and the efficiency
