2 cards from this section. Quick, good the night before a test.
Define specific heat capacity.
Think about what we measure in relation to temperature and mass.
What is Q in the specific heat capacity equation?
Consider what happens to energy as temperature changes.
What is the specific heat capacity of water?
Consider which material is commonly used in thermal management.
Is specific heat capacity the same for all substances?
Think about how metals and water behave when heated.
A 2 kg block of copper (specific heat capacity ≈ 0.385 J/g°C) is heated from 20°C to 100°C. Calculate the total heat energy required in Joules.
Ensure all units are in grams for consistency.
A liquid with a specific heat capacity of 4.2 J/g°C is heated from 30°C to 90°C in a calorimeter that absorbs no heat. If the mass of the liquid is 500 g, how much heat is gained?
Remember to apply the equation correctly by setting the temperature differences.
