- - - - The effects of heat gaining or heat lossing
        
        Heat gain can cause
        
        Temperature to increase
        
        A solid to change to a liquid
        
        A liquid to change to a gas
        
        Matter to expand
        
        Heat loss can cause
        
        Temperature to decrease
        
        A liquid to change ti solid
        
        A gas to change to liquid
        
        A matter to contract
      - Heat travels from a hotter object or place to a colder object or place until both reaches the same temperature .
      - materials that allow or do not allow heat to easily pass through them
        
        heat cannot easily pass through poor conductors of heat
        
        heat can easily pass through good conductors of heat
