A convex mirror is used as a driving mirror; however, a disadvantage in this regard is that the image

The amount of heat energy that will be extracted when 0.02kg of water vapor condenses to water at 97ºC is [specific heat capacity of water = 4200Jkg\(^{-1}\)k\(^{-1}\), Specific heat of vaporization of water = 2.26 x 10\(^6\)Jkg\(^{-1}\)]

Water is readily available but it is not a thermometric liquid mainly because 

The constant temperature at which a liquid change into gaseous state is known as
