60s - Q4
What best explains the reason solids have a definite shape and volume?
the molecules in solids move past each other easily.
the molecules in solids do not move at all.
the molecules in solids move freely in all directions.
the molecules in solids stay in a definite location and vibrate
60s - Q5
Brian's family has a compost pile at home. They put all the weeds they pull up from the garden in it as well as any vegetable waste they gather from the kitchen. If they keep it moist, all this vegetation will eventually turn into organic soil by the chemical process of decay. Since decay involves a variety of chemical reactions, how might temperature affect the rate at which the compost turns into soil?
Changing temperatures would not affect the chemical reactions.
Temperatures near freezing would make it speed up
Warm summer air temperatures would make it slow down.
It would happen faster at warmer air temperatures.
120s - Q6
What happens to particles when their temperature increases?
The particles gain mass
The particles move slower
The particles lose mass
The particles move faster

60s - Q8
Predict what would happen to a glass of drinkable water if left outside overnight in negative degree weather.
The water would change to a gas
The water would change to a solid
The water would stay the same
60s - Q9
If a cup of hot chocolate is put in the microwave, would that add or remove thermal energy to the hot chocolate.
Thermal energy is removed
Thermal energy is added
