Black powder is made of 75% saltpeter (potassium nitrate; KNO3), 15% charcoal (carbon), and 10% sulfur. What is the mass of KNO3, Carbon, and Sulfur in a 150 gram sample of black powder?

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 .
