Specific Heat Capacity | GCSE Physics Practice
SHC is the energy required to raise the temperature of 1kg of a material by 1°C.
Why does the sea stay cool in summer while the sand is hot?
What is Specific Heat Capacity | Practice?
"The energy needed to raise the temperature of 1kg of a substance by 1°C."
Specific heat capacity is the energy needed to raise 1kg of a substance by ____.
Calculate the energy needed to heat 2kg of water from 20°C to 30°C. (SHC of water = 4200 J/kg°C)
Water has a very high specific heat capacity. What does this mean compared to a metal?
SHC Essentials
Change in thermal energy = mass x SHC x temperature change.
Water has a high SHC (4200 J/kg°C).
Metals usually have low SHC and heat up quickly.
Misconception: Temperature and Thermal Energy are NOT the same. Energy is the store; temperature is the average kinetic energy.
