To calculate the amount of heat needed to melt ice;
Q = w x Cp x ∆T {where Cp is specific heat of material}
=100.0g (4.186J/g°c) (-60°C)
=-25116J
Heat lost by water is gained by ice,
q = m*ΔH
-25116J = m*333J/g
q = -75.4
Therefore, Mass of ice is 75.4 g.
What is mass?
It is a dimensionless quantity that expresses a particle or object's mass. The accepted unit of mass under the International System (SI) is the kilogram.
What is temperature?
Temperature is a measure of the average kinetic energy of the particles inside an object. The temperature increases cause these particles to move more quickly. It is possible to measure temperature using a thermometer or a calorimeter.
