Earth Materials - The Rock Forming Minerals - Historical Geology
Most of the minerals of Earth's crust formed through the cooling of molten rock (magma or lava). Molten rock is very hot, typically on the order of 1000 °C (1800 °F) or more. Heat is energy and temperature is a measure of that energy. Heat causes atoms to vibrate and temperature measures the intensity of the vibration.

The more cold, solid objects you have in your room, the more heat energy you have to supply to heat them all up to a particular temperature.

How does solubility change with temperature changes?
Usually, increasing the temperature increases the solubility of solids and liquids. Increasing the temperature always decreases the solubility of gases. When you add a solute to a solvent, the kinetic energy of the solvent molecules overcomes the attractive forces among solute particles. The solute particles leave the surface of the solid and move into the dissolved (aqueous) phase.
