a. solid = very little particle movement, fixed, barely any space between particles
b. liquid = quite a bit of particle movement, variable, lots of space between particles
c. gas = lots of particle movement, variable, huge amounts of space between particles
2.
a. soup is hotter than room temp so it loses energy to the 'colder' air
b. ice cream is colder than room temp so it gains energy from the 'hotter' air
3.
a. #1
b. same in both ** glass 1
c. transfer from #1 to #2
4.
a. boiling water
b. iceberg
5.
the wire will tighten because it will shrink since the heat is gone (the particles will grow closer together)
6.
a. copper because it absorbs the heat faster and therefore melts the ice faster
b. rubber because it took longer to heat up and therefore melted the ice slower
c. either of glass or of the same material the stick is made of but unheated ** faster one is copper, slower one is rubber (the slower it melts, the material changes)
7.
a. radiation
b. conduction
c. convection
8.
a. plastic cap = conduction, no heat is transferred upon contact ** convection
b. stopper = convection, the heat that drifts up is contained **correct, also conduction
c. shiny interior = conduction, prevents heat from escaping on touch ** radiation
d. shiny exterior = conduction, prevents heat from escaping on touch ** radiation
e. vacuum = radiation, the heat had a bit of wiggle room, can heat up the vacuum which continues to heat up the liquid inside ** conduction/convection
f. air space = radiation, the heat bounces off the shiny interior and exterior but can't get out **conduction
g. plastic stand = convection, prevents colder energy to stay at the bottom ** conduction
9.
if she heats the ring and makes the ball colder, the ball will fit through the ring
