Imagine that the oxygen cup had 2 models: one with 2 white cubes snapped together and the other with 3 white cubes snapped together. Would this be a pure substance in the cup?

dynamic equilibrium is the answer.

the formula for the conversion of temperature from degree celsius to kelvin is:

the sample of water at is converted to kelvin temperature by using the above formula as:

on comparing the two samples of water at or we can say that at and at respectively. the difference between the temperatures of two samples of water is:

hence, one can say that the sample of water at is greater than the sample of water at by .
