How much energy is needed to raise the temperature of 2.5 moles of alumina from 0C to 120 C, taking To calculate heat capacity, use the formula: heat capacity = E / T, where E is the amount of heat energy supplied and T is the change in temperature. For example, if it takes 2,000 Joules of energy to heat up a block 5 degrees Celsius, the formula would look like: heat capacity = 2,000 Joules / 5 C.

Aluminium Oxide (Al2O3) or alumina is one of the most versatile of refractory ceramic oxides and finds use in a wide range of applications. Aluminium Oxide (Al2O3) or alumina is Why do metals have high specific heat? Metal atoms in pure metal are very close together and are able to transfer heat easily via conduction from one atom exciting the other atoms next to it. So the amount of energy it takes to heat a metal is relatively small to that of water. Molecular weight: 101.9613.
