Give two examples each of (a) an isothermal change and (b) an adiabatic change.

Answer

(a) Isothermal change.
1. A gas contained in a metallic cylinder and compressexd or allowed to expand slowely.
2. Boyle's law.
(b) Adiabatic change.
1. A gas contained in a non-conducting cylinder and compressed or allowed to expand quickly.
2. Air escaping from the cycle tube on removing the value undergoes adiabatic expansion.
