Heat Capacity

Heat Capacity

Heat capacity ‘Heat capacity’ is the amount of heat to raise the temperature of an object by 1℃. The heat capacity of an object is the specific heat of the object multiplied by the object’s mass. … more

Charle’s Law Charle’s Law In 1787, French scientist Charle (1746-1823) revealed that increasing the temperature of a gas by 1℃ at constant pressure increases the volume of the gas by 1/273 of the volume at 0℃. … more

Avogadro's Law

Avogadro’s Law

Avogadro’s Law The Italian scientist Avogadro (1776-1856) introduced the molecules’ concept to explain gases’ reactions. According to his theory, the volume of any gas at the same temperature and pressure is proportional to the molecules’ number. … more
