A:-the substance is solid at this stage. L:-substance has reached room temperature
-strong bonds, vibrates at a fixed position.
-closely packed in an orderly fashion.
A-B:-heat energy is converted to kinetic energy. K-L:-solid
-vibrates a little faster, temperature rises. -Temperature decreases
B-C:-heat released here, latent heat of fusion. J-K:-liquid changing to solid
-temperature remains constant. -particles arranged into an ordered pattern
-melting point.
C:-Liquid only. J:-starts to freeze into a solid
C-D:-temperature continues to rise. I-J:-move closer to each other
-particles move faster -vibrate slower, temperature decreases
D:-some molecules start to move freely I:-Liquid
-starts changing from liquid to gas.
D-E:-Boiling point H-I:-continuation of condensation
-heat used to break bonds -stronger bonds form, gas to liquid
-temperature stays the same -latent heat of evaporation, boiling point
E:-Gas H:-start to form inter molecular bonds
-condensation begins, liquid starts to form
E-F:-particles move faster G-H:-kinetic energy decreases
-temperature increases as heating continues. -particles are getting closer
-temperature decreases
If you are looking to replace or buy a new heating and cooling system but want something that may be more efficient or more environmentally friendly than a traditional furnace system, you have a few options to choose from. Keep in mind that each of these alternative heating and cooling systems can operate efficiently but it depends on your home’s location, size, and layout.
