Science Notes on Physical and Chemical Properties
... Example – Tear a piece of paper into 10-15 pieces. The shape and size have changed, but its still paper Example – Change of state = physical change…add energy to ice and you get a liquid…add more energy and you get a gas…all physical changes as it is still water Example – Dissolving things is a phys ...

Matter, Mass and Weight
... Energy of an isolated system always remains constant. Energy may be converted from one form to another, but cannot be created or destroyed. A system can exchange its energy with its surrounding in two forms: heat and work. When a gas is in contact with an object at higher temperature, energy flows i ...
