Powerpoint lecture covering the following in a modern, concise format:

Specification Point 5.8P - Explain why heating a system will change the energy stored within the system and raise its temperature or produce changes of state.

Specification Point 5.9P - Describe the changes that occur when a solid melts to form a liquid, and when a liquid evaporates or boils to form a gas.

Specification Point 5.10P - Describe the arrangement and motion of particles in solids, liquids and gases.

Specification Point 5.11P - Practical: obtain a temperature鈥搕ime graph to show the constant temperature during a change of state.

Specification Point 5.12P - Know that specific heat capacity is the energy required to change the temperature of an object by one degree celsius per kg of mass.

Specification Point 5.13P - Use an equation to derive the change in thermal energy in a system.

Specification Point 5.14P - Practical: investigate the specific heat capacity of materials including water and some solids.
