As the temperature is increased they will melt and become liquids. Each element melts at a different temperature, called it's melting point. Hydrogen melts at -259 degrees Celsius. Mercury melts at -39 degrees Celsius. Iron melts at 1,535 degrees Celsius. As the temperature is increased still further, each element will boil and become a gas. Each element boils at a different temperature, called the boiling point.
