1.	1. Explain the first, second and third laws of thermodynamics.2. What do you meant by entropy?3. Explain the spontaneous process.
Answer» 1. First law: Energy can neither be created nor be destroyed. Energy in one form can be converted into another form without any loss or gain. Second law: Entropy of the universe increases during a spontaneous process. Third law: Entropy of a perfect crystalline substance is zero at absolute zero of temperature. 2. Entropy: Entropy is a measure of randomness or disorder of a system. 3. Spontaneous process: A spontaneous process is defined as an irreversible process which has a natural tendency to occur either of its own or after proper initiation under the given set of conditions.
