Understanding Specific Heat Capacity

Front

What is specific heat capacity?

Back

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

Front

What is the symbol for specific heat capacity?

Back

C

Front

How does specific heat capacity affect temperature changes in coastal areas compared to inland areas?

Back

Coastal areas have moderated temperature changes due to the high specific heat capacity of water.

Front

What is the specific heat capacity of water in joules per kilogram per degree Celsius?

Back

4186 J/kg°C.

Front

What is the specific heat capacity of iron in joules per kilogram per degree Celsius?

Back

450 J/kg°C.

Front

What is the formula to calculate heat absorbed or released?

Back

Q = c m ΔT, where Q is heat, c is specific heat capacity, m is mass, and ΔT is the change in temperature.

Front

What does the variable 'Q' represent in the specific heat formula?

Back

Q represents the amount of heat energy absorbed or released.

Front

What does the variable 'm' represent in the specific heat formula?

Back

m represents the mass of the substance.

Front

What does the variable 'ΔT' represent in the specific heat formula?

Back

ΔT represents the change in temperature, calculated as final temperature minus initial temperature.

Front

How do you calculate the heat absorbed by water in an experiment?

Back

By using the specific heat equation for water: Q = c m ΔT.
