the mass of cobalt-60 in a sample is found to have decreased from 1.6 grams to 0.40 grams how long did the sample decay if the half-life of cobalt-60 is 5.3 years

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 .
