Everyday Physical Chemistry in Your Kitchen and Home

Boiling water shows phase changes—heat energy turns liquid molecules into vapor.
Ice cubes melting in a drink reveal heat transfer from warmer liquid to colder solid.
Baking bread is a mix of thermodynamics (heat), kinetics (rising), and chemistry (Maillard reactions).
Nonstick pans use surface chemistry to keep food from clinging.
Refrigerators apply thermodynamics—compressing and expanding gases to move heat out.
Soap bubbles balance surface tension and air pressure, a playful display of molecular forces.
Microwave ovens excite water molecules with radiation, heating food from the inside out.
Brewing coffee or tea extracts flavors through diffusion and solubility principles.
Rust on a sink or pan is electrochemistry happening in plain sight.
Even ironing clothes is physical chemistry—heat and water vapor relaxing molecular bonds in fabric.
