Chemistry: Thermal Energy

posted by .

Hi! I have a quiz tomorrow and there are a couple of things that I am confused about:

-Why does heat cause convection currents in gases and liquids, but not solids?
-How can one object feel warmer than another object if they are at the same temperature?
-Why doesn't the temperature change during a phase change? What is happening to the added energy during these times?

Thanks in advance!

  • Chemistry: Thermal Energy -

    1. Molecules in gases and liquids have the freedom to move around; not so in solids.
    3. At the melting point the added energy is going to melt the material; at the boiling point it is going to vaporize the material.
    2. Whether an object feels hot or cold depends upon which way the heat is flowing between the object and the "person."
