Specific Heat Capacity
Learning Objectives
- Students will be able to define specific heat capacity and explain why it varies between substances
- Students will be able to calculate specific heat capacity from experimental data
- Students will be able to solve calorimetry problems involving multiple substances
Core Concepts
- specific_heat_capacity
- heat_capacity
- material_property
- calorimetry
- thermal_inertia
Formulas
$$c = \frac{Q}{m \cdot \Delta T}$$
Specific heat capacity equals heat divided by mass and temperature change
$$Q = mc\Delta T$$
Heat energy calculation using specific heat capacity
Units
| joule per kilogram per kelvin | J/kg·K |
| calorie per gram per degree celsius | cal/g·°C |
Interesting Fact
The specific heat of ice (2090 J/kg·K) is less than half that of water, which is why ice temperature changes more rapidly than water
Key Scientist
Joseph Black
Developed the concept of specific heat capacity and latent heat
Ancient Wisdom
Different beings require different amounts of 'heat' (effort, grace) to transform; this physical insight validates the spiritual principle of individual variation in capacity.
