6-Exothermic Processes

• Calcium dissolves in water to form calcium chloride solution.

  It is an exothermic process as heat energy is released to the surroundings. These exothermic processes are used for ice packs
• When a liquid is cooled, the particles lose energy to the surroundings and move slower.

  The attractive forces between particles become stronger as they come closer together.

  Eventually, the forces are strong enough

  to form bonds between the particles

  and hold them in tight positions.

  Heat is released when strong bonds are packed between the particles.
