Heat and Temperature - Coggle Diagram

- - - - Black, dull, and rough surfaces
        
        Best absorbers of heat
      - White, shiny and smooth surfaces
        
        Poor absorbers of heat
  - - - Cooling coils of refrigerator are painted black
        
        Absorb heat from refrigerator
  - - - Gases > Liquids > Solids
    - - Solids
        
        The metal ring is heated
        
        Solids expand upon heat gain
        
        Lengths of Solids increases
      - Liquids
        
        Water level drops when heated intially
        
        Water level increases after heating for a while
        
        Expansion in liquids
        
        Water level rises
      - Gas
        
        Air bubbles are seen inside the water
        
        Gases expand upon heat gain
        
        Causes gaseous particles to occupy more spaces
        
        Some of them are forced out of the flask
- - - - Changes in States of Matter
        
        Solid -> Liquid = Melting
        
        Liquid -> Gas = Boiling/Evaporation
      - Expansion of Matter
        
        After gaining heat, matter expands and becomes bigger
  - - - Changes in States of Matter
        
        Gas -> Liquid = Condensation
        
        Liquid -> Solid = Freezing
      - Contraction of Matter
        
        After losing heat, matter contracts and becomes smaller
  - - - Metals
      - Allows heat to flow through
    - - Plastics
      - Rubber
      - Glass
      - Air
      - Fabrics
      - Wood
      - Does not allow heat to flow through
- - - - Measure things during experiments
      - Longer range of temperatures
    - - Measure human bodies
      - Shorter range of temperatures
