Answer:
D: Melting of ice. is it correct?
A calorimeter is a device used to measure the amount of heat involved in a chemical or physical process. For example, when an exothermic reaction occurs in solution in a calorimeter, the heat produced by the reaction is absorbed by the solution, which increases its temperature.
We use the following formula for calculating the density:
p = m/v
Where:
m = mass
v = volume
So, we have:
p = 46 /5
p = 9,2 g/cm³
The answer is Joule. Kilograms and Grams is a unit for weight
