A sample of metal has a mass of 21.17 g, and a volume of 7.98 mL. What is the density of this metal? density:

2.652882206 but it depends on how you round it so I would say 2.65 or 2.7 g/mL

Explanation: Density is mass divided by volume

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 .
