Question

the physical state of water at a temperature of 100K is a) solid. b)liquid
c) vapour. d)plasma

Answer 1

hlo mate
....

Answer: (a) Liquid, (b) Solid and (c) gas. (a) Water at room temperature is a liquid. (b) an iron almirah is a solid at room temperature. Answer: (a) water at room temperature is liquid because at this temperature (i)it has fixed volume and (ii)it can flow.

Answer 2

Lets assume that water is pure .........

Water at 0° C becomes a solid on losing the latent heat.

Water above 100° C becomes a gas .

The temperature of pure water below 0° C is a solid !

The temperature between 100 and 0°C is for liquid state .

Temperature is 100 K

Convert this to °C

100 K = 100 - 273

         = - 173°C

Obviously this will be in solid state as it is below 0° C.

Beware that if further more temperature is decreased , it may enter into the state of Bose-Einstein Condensate !
