Summary
Temperature tells degree of hotness. Heat is energy transferred because of temperature difference.
Most substances expand on heating and contract on cooling. ICSE applications include bimetallic strip, gaps in bridges and anomalous expansion of water.
Calorimetry uses heat lost = heat gained. Latent heat changes state without changing temperature.
