Heating Curves
what portion of the heating curve represents phase changes?
the horizontal parts
this state has no defined shape or volume. what state is this?
gas
how are particles arranged in a solid?
what law says that temperature and pressure are directly related
gay-lussac's law
if a balloon shrinks in the warm house after you bring it into the cold air, which gas law is this?
boyle's law
do the boiling and freezing point change with each substance
yes.
this state has a defined volume but no defined shape. what state is this?
liquid
how are particles arranged in a liquid?
they are more spread out than a solid, but still touching each other
what law says that volume and pressure are inversely related
boyle's law
a substance has charged particles that take the space of a container. what state of matter is the substance in?
if a substance with a freezing point of - 10 degrees Celsius changes state after every 60 degrees, what state will the substance be in at 90 degrees?
liquid
this state has both a defined volume and a defined shape. what state is this?
solid
how are particles arranged in a gas?
very spread apart and don't touch
what law says that temperature and volume are directly related
Charles' law
why are gas particles far apart?
what is it called when a substance goes from liquid to gas?
evaporation
this state has charged particles. what state is this?
plasma
what happens when particles are hot?
they start moving faster
what does inverse mean?
when one goes up the other goes down
true or false: solid particles are closer together than every other substance
true
what portion of the heating curve represents the state of matter?
the slanted part
what generally happens when you add temprature to a solid object?
it becomes a liquid then a gas
what happens when particles are cooled?
they slow down
which two laws have a graph with a straight line going upwards?
Gay-Lussac's and charles'
what happens to particles as heat is taken away?
they become more condensed and slow down
