Need now Use the drop-down menus to complete a description of Malik’s model.

The model will show that the volume of the balloon blank
after several hours in the freezer. The model will explain that blank
thermal energy from the helium molecules in the balloon will
blank the motion of the helium molecules. The volume of the balloon
blank on the amount of molecular motion.

answer: the metamorphic rocks are formed when they are exposed to high pressure and high temperatures. this happens when one of the earth's plates comes in contact with the other plate by traveling in opposite directions, straight into each other or slipping under one another. the friction that is caused by this activity results in   melting of rocks and when it cools they are known as metamorphic rocks. this process needs a controlled amount of pressure and temperature otherwise it may turn into magma.
