Describe the Motion of Particles in a Solid
310 describe the effects of changes in surface area of a solid concentration of a solution pressure of a gas temperature and the use of a catalyst on the rate of a reaction 311 explain the effects of changes in surface area of a solid concentration of a solution pressure of a gas and temperature on the rate of a reaction in terms of. This is made up of particles that are tightly or closely packed together such that they do not move pass each other but vibrates along a fixed axes. The Particulate Nature Of Matter Igcse Cambridge 2019 2021 Teaching Resources States Of Matter Matter Science Matter Worksheets The particles will gain energy and expand. . When a solid turns into a liquid it is called melting. Particles are closely connected in a crystal lattice vibrate slightly on the spot-Has a definite shape and volume. In a solid the particles pack together as tightly as possible in a neat the particles are held together too strongly to allow...
