Front

What is specific heat capacity (c)?

Back

It is a material property defining how much heat energy (Q) is required to raise the temperature of one kilogram by one Kelvin.

Front

What is the formula for calculating heat energy (Q)?

Back

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

Front

What is the specific heat capacity of water?

Back

Approximately 4181 J/(kg·K).

Front

Why is water's high specific heat capacity effective?

Back

It makes water effective for thermal storage and temperature moderation.

Front

What is the specific heat capacity of aluminium?

Back

Approximately 900 J/(kg·K).

Front

How much energy does 2 kg of water absorb when heated from 20 °C to 30 °C?

Back

Approximately 83.6 kJ.

Front

What engineering applications leverage specific heat capacity?

Back

Central heating systems, automobile radiators, and calorimetry experiments.

Front

How do central heating systems utilize specific heat capacity?

Back

They circulate water to transport heat efficiently.

Front

How do automobile radiators use specific heat capacity?

Back

They remove engine heat by flowing coolant with high specific heat capacity.

Front

What is the purpose of calorimetry experiments?

Back

To measure unknown specific heats by monitoring temperature changes under known energy input.
