What is specific heat capacity?

Back

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

Front

What is the formula to calculate heat energy required to raise the temperature of any substance?

Back

Q = mc∆t

Front

What does 'm' represent in the formula Q = mc∆t?

Back

In the formula Q = mc∆t, 'm' represents the mass of the substance in grams.

Front

What does 'c' represent in the formula Q = mc∆t?

Back

In the formula Q = mc∆t, 'c' represents the specific heat capacity of the substance in J/(g°C).

Front

What does '∆t' represent in the formula Q = mc∆t?

Back

In the formula Q = mc∆t, '∆t' represents the change in temperature in degrees Celsius.

Why does sand get hotter than water at the beach?

Back

Sand has a lower specific heat than water, meaning it heats up faster.
