a) Two gases are - LPG(Liquid Petroleum Gas) and CNG(Compressed Natural Gas)
b) We are able to do this because evaporation is a surface phenomenon. The large the surface the more evaporation it will have. That means it cools fast.

(a) LPG AND CNG
(b) the rate of evaporation increases with an increase of surface area in the case of saucer as compared to the cup. so we are able to sip hot tea or milk faster from a saucer rather than a cup .
