Basic Thermodynamics Concepts
Energy, heat, and work basics
Basic thermodynamics covers how energy is conserved, how heat moves via conduction, convection, and radiation, and how entropy trends define process direction and efficiency.

Energy and Work
Systems exchange energy as heat or work; total energy is conserved.
Heat Transfer
Conduction, convection, and radiation move heat between bodies.
Entropy and Efficiency
Entropy increase limits efficiency; real processes lose usable energy.

Comparison
Mitosis vs Meiosis
Mitosis makes matching cells for growth and repair, while meiosis creates sex cells and introduces genetic variation.
