As we stand and watch the hot air balloon rise in the sky, we can imagine what is happening at the microscopic level to the gas molecules inside the balloon. As the balloon rises, the gas molecules are

moving faster and spreading apart.

slowing down and moving closer together.

gradually escaping from the confines of the balloon.

all collecting at the top of the balloon, pushing upward.

As ice transforms into steam,

energy is absorbed by the molecules.

the types of atoms are changed.

the mass of the molecules is increased.

Solids are often defined as having a definite shape, while gases and liquids have no definite shape. This can best be explained by the fact that

solids have a more ordered arrangement of atoms than liquids and gases.

in solids molecules move faster than in liquids or gases.

solids have less internal energy than liquids and gases.

solids have the least orderly internal structure.

Elaborate on the reason(s) that matter is said to move even as in a solid state.

The particles are not able to move out of their positions relative to one another, but do have small vibrational movements.

The particles are bound through intermolecular forces but are able to move past each other with relative freedom.

The particles have sufficient energy to become an ionized gas and are in the most common state of matter in the universe.

The particles are not bound to one another, move quickly, have a low density, and are able to spread apart from one another if unconstrained.

Which of these statements best supports the conclusion that a substance is in the plasma phase?

The substance contains charged particles.

The substance has low kinetic energy.

The substance is at a high temperature.

What is the relationship between the internal energy of a substance and its state of matter?

As the internal energy decreases a substance will spread further apart.

As a gas loses internal energy it becomes a plasma.

Closer packed atoms generally have more internal energy.

As the internal energy decreases a substance will spread further apart.

When a solid such as ice begins to melt, heat energy is added. What is the function of this added heat energy?

to break the bonds between the individual water molecules

to separate hydrogen atoms from oxygen atoms

to add energy to the hydrogen bonds among water molecules

A substance heats and cools quickly. What do you know about this substance?

It has a low specific heat capacity.

It has a high specific heat capacity.

It is undergoing a phase change.

What is going to happen to the volume of a gas that is put under MORE pressure while keeping the temperature constant?

The volume will remain constant.

Why might a balloon, that is inflated almost to its capacity, pop or explode on an extremely warm day?

the balloon might pop due to the increase in the volume of the gas.

It might pop because of the weakening of the balloon by the heat.

The balloon might pop because the volume will decrease within the balloon.

6 A.M. - 30 PSI 9 A.M. - 32 PSI 1 P.M. - 35 PSI Amy measured the tire pressure of her truck that was parked outside after a cold night. The daytime temperature reached a nice 65 °F. Assume Amy's tires do not have any leaks. Explain the change in tire pressure.

The air molecules heated inside the tire causing them to move faster exerting more pressure on the inside walls of the tires.

The air molecules heated inside the tire causing them to move faster exerting less pressure on the inside walls of the tires.

The air molecules heated inside the tire causing them to move slower exerting more pressure on the inside walls of the tires.

The air molecules heated inside the tire causing them to move slower exerting less pressure on the inside walls of the tires.

How will the behavior of the gases in the piston chamber change if more pressure is applied to the piston?

The gas particles will hit the walls more frequently.

The gas particles will slow down.

More gas particles will be produced.

Fewer gas particles will be produced.

Jessica took a mylar balloon outside on a very cold day. As she waited for the bus the balloon began to shrink. What is the best explanation of this?

As the particles became cooler, they lost energy and moved less, resulting in less pressure on the balloon.

As the particles became cooler, they gained energy and moved less, resulting in less pressure on the balloon.

As the particles became cooler, they lost energy and moved less, resulting in more pressure on the balloon.

As the particles became cooler, they gained energy and moved less, resulting in more pressure on the balloon.

Jenavius placed a marshmallow in the microwave to make a smore for desert. The marshmallow expanded when it was heated. How can you best describe why this happened?

As the marshmallow was heated the particles moved faster increasing its volume.

As the marshmallow was heated the particles moved faster decreasing its volume.

As the marshmallow was heated the particles moved slower increasing its volume.

As the marshmallow was heated the particles moved slower decreasing its volume.

How is the temperature of a gas related to the kinetic energy of its particles?

As the temperature increases, the kinetic energy of the particles increases.

As the temperature extends, the kinetic energy of the particles decreases.

As the temperature decreases, the kinetic energy of the particles increases.

As the temperature intensifies, the kinetic energy of the particles decreases.

Ladasha placed a marshmallow in a syringe for science class when she pulled the plunger out increasing the volume in the syringe the marshmallow expanded. How can this best be explained?

As the pressure decreased in the syringe the volume of the marshmallow increased.

As the pressure increased in the syringe the volume of the marshmallow increased.

As the pressure decreased in the syringe the volume of the marshmallow decreased.

As the pressure increased in the syringe the volume of the marshmallow decreased.

Where are valence electrons located?

elecrons in outer most energy level

electrons in inner energy level
