It's a hot summer day. You took a trip to the beach but lost your shoes.

When it's time to return to the car, you have two choices: the black asphalt parking lot or the strip of fresh grass next to it. Your feet are already sensitive from the hot sand.

  • But why?

Different materials need different amounts of energy to heat up.

That means that when different materials are heated with the same amount of energy, their temperatures will change at different rates.

Let's look at another example. It's time to boil some pasta. You fill the pot with cold water and place it over the burner.

The amount of energy needed to heat up a certain material is referred to as the material's specific heat capacity, also referred to as specific heat or heat capacity.

To be exact, an object's specific heat is the amount of energy (in the form of heat) needed to increase the temperature of 1 kilogram of that material by 1 degree Celsius.
