Thermal properties of matter

Define specific heat capacity

Energy needed to raise temperature of 1kg of substance by 1°C

Specific heat capacity equation and its unit

Capacity= energy needed/mass x temperature

Unit= Jules J/Kg°C

Temperature/Energy equation

Temperature/energy= MxCx^T (Mass x Capacity x Temperature)

^T= °C - °C

What happens to ice cube when it melts

The particles vibrate more, breaking the bonds holding the solid structure.

Define thermal expansion

Increase/decrease size of body because of change in temperature

Differentiate between boiling and evaporation

Boiling: occurs at a fixed temperature, temperature remains same

Evaporation: occurs at any temperature, temperature decreases
