Specific Heat Capacity

Specific heat capacity is the amount of energy required to raise the temperature of 1 gram of a substance by 1 degree Celsius.

Some materials heat up quickly, while others warm more slowly. One important reason is a property called specific heat, which tells us how much energy is needed to change a material’s temperature.

Water, for example, has a high specific heat capacity. That means it can take in a lot of heat without its temperature changing quickly. Because its molecules are strongly attracted to each other, it takes more energy to make them move faster and raise the temperature.

Oil, on the other hand, has a lower specific heat capacity and heats up much faster. This is because the attraction between oil molecules is weaker.

As a result, less energy is needed to warm it up, so oil cooks food quickly and makes it crispy.

However, if you want something to stay warm for a longer time, like in a hot water bag, water is the better choice because its high heat capacity helps it absorb and store heat longer.
