If you compare ice & water on the molecular level, you could say that

molecules in water are closer together

When a thermometer is heated, the red liquid goes up because

the molecules move faster and further apart

Condensation occurs when

the gas molecules cool, slow down and stick together

Hot water evaporates faster than room temperature water

water molecules move fast and break away

When water freezes,liquid water turns to solid ice mainly because

molecules slow, attract, & keeps them in a fixed spot

Which of the following is an example of matter?

the air in the Earth's atmosphere

it can be seen with the human eye
it is the basic unit of matter
it is made of several compounds bonded together
it can be broken down into elements
4
When a thermometer is heated, the red liquid goes up because
red liquid is thin
the molecules move faster and further apart
liquid is lighter
the glass of the thermometer gets hot
5

no the are rigidly held in place
yes, they vibrate in place
no they are fixed
Yes, they slide past other atoms
6

gas
solid
liquid
8
Identify what state of matter this picture is.
liquid
solid
gas
9
Condensation occurs when
the gas molecules cool, slow down and stick together
the molecules get lighter
the molecules grow
molecules of a liquid escape into the air
10
Energy can be added or removed from a substance through a process called________?
conduction
sublimation
evaporation
melting
11
_________is the process that causes a substance to change from a liquid to a gas.
melting
sublimation
evaporation
condensation
12
Hot water evaporates faster than room temperature water
room temperature water has more mass
molecules of hot water are lighter
water molecules move fast and break away
molecules in room temperature water are faster
13
When water freezes,liquid water turns to solid ice mainly because
water eventually becomes ice
ice can float on water
molecules slow, attract, & keeps them in a fixed spot
water molecules get harder
14

molecules are small
molecules are larger
molecules are less dense
water molecules move quicker
15

decreases
faster
increases
farther apart
16
