Because each substance's particles have a different mass, it takes a different amount of heat energy to get them moving at a certain speed ie have a certain temperature.
As a result different substances change temperature by different amounts when supplied the same amount of energy. The specific heat capacity of a substance is the amount of energy required to change the temperature of one kilogram of the substance by one degree Celsius. It is calculated using the following equation:
E = m × c × θ
where: E is __________ transferred in __________, J m is __________ in __________, kg θ is __________ change in degrees __________, °C c is __________ heat capacity in J / kg °C
Each day the average European family uses 100 kg of hot water.
To kill bacteria, the water going into the tank at 20°C must be heated to 60°C.
