Thermal Properties of Matter

Heat required to change temperature of 1 kg substance by 1 K

Specific heat capacity is the amount of heat required to raise the temperature of 1 kg of a substance by 1 Kelvin.

4°C

Water exhibits an anomalous behavior and has its maximum density at 4°C, which is crucial for aquatic ecosystem survival.

3.33 × 10⁵ J/kg

The latent heat of fusion for water is 3.33 × 10⁵ J/kg, representing the heat required to melt 1 kg of ice at 0°C.

Celsius

The Celsius scale defines 0°C as the freezing point of pure water under standard atmospheric pressure.
