13.
Jocelyn used a balloon to make a model of gas particles. She measured the balloon's diameter at room temperature. Then, she placed the balloon in a freezer. An hour later, she removed the balloon from the freezer and measured the diameter immediately after. Jocelyn made these drawings to show the balloon's diameter at room temperature and immediately after removing it from the freezer. The dotted line represents the size of the balloon before placing it in the freezer. Then, Jocelyn placed the balloon in a tub of heated water that is warmer than the room temperature. Which is the best prediction of what may happen?
a)
The balloon expands to a diameter of 10 cm and stops because the gas particles return to their original movement.
b)
The balloon expands to a diameter over 10 cm because the gas particles move faster
c)
The balloon shrinks to a diameter below 9.4 cm because the gas particles move slower
d)
The balloon remains at a diameter of 9.4 cm because the gas particles maintain their current movement
14.
Model X and Model Y both represent particles of the same substance. Identify the states of matter represented by Model X and Model Y
a)
Model X is a liquid, Model Y is a solid
b)
Model X is a gas, Model Y is a solid
c)
Model X is a solid, Model Y is a liquid
d)
Model X is a liquid, Model Y is a gas
15.
Juana is creating a lab simulation about the movement of the particles in a nonmetal gas. The user can change the pressure in the gas' temperature and see the effect of the change in the gas' volume. What change should Juana program to cause the decrease in the gas' volume?
a)
decrease in pressure
b)
increase in pressure
c)
increase in temperature
16.
