1. Temperature and Heat
Temperature is a measure of hotness. Heat is the energy transferred due to temperature difference. Q = mcΔT.
2. Laws of Thermodynamics
- Zeroth Law: Explains thermal equilibrium.
- First Law: Energy conservation for thermal systems: ΔU = Q - W.
- Second Law: Entropy of an isolated system always increases; heat cannot flow spontaneously from cold to hot.
3. Ideal Gas Law
Relates pressure, volume, and temperature: PV = nRT.
