In today’s class we learned about specific heat capacities and how to calculate them. The specific heat capacity is the amount of heat transferred when the temperature of 1.0 kg of the substance changes by 1°C Here’s the formula and an example:
The formula:
Energy
———-
Mass x Temperature Change
An example:
If it takes 8000J to heat 100g of oil from 30°C to 70°C the formula (with relevant values inserted) is:
8000 J
——-
0.1 kg x 40°C
=
20,000 J (kg C°)
