The universe cooled after the big bang. at some point, hydrogen atoms combined to form helium. what is this process called?

idk what is it? is this a question that you know the answer or u dont

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 .
