Heat and Thermal Energy Transfer
Learning Objectives
- Students will be able to define heat as thermal energy transfer between objects
- Students will be able to calculate heat energy using Q = mcΔT
- Students will be able to apply conservation of energy in thermal systems
Core Concepts
- thermal_energy_transfer
- temperature_difference
- heat_capacity
- calorie
- joule
Formulas
$$Q = mc\Delta T$$
Heat energy required to change temperature (c is specific heat capacity)
$$Q = mL$$
Heat energy for phase changes (L is latent heat)
Units
| joule | J |
| calorie | cal |
Interesting Fact
A calorie (used in nutrition) is actually a kilocalorie, equivalent to 4184 joules
Key Scientist
James Joule
Determined the mechanical equivalent of heat and showed heat is a form of energy
Modern Research
Thermal engineering relies on understanding heat transfer for climate control, power generation, and industrial processes.
