Question 16

As temperature rises from 25°C to 60°C, the material _______ heat and its kinetic energy _________ as the material goes through vaporization to become a gas.

Accepted Answer

absorbs, increases

Answer

multiplies its, is divided

Answer

remains the same, decreases

Question 17

The task in science lab: discover which solid substance, without tasting, is sugar. Donna and Dave have five substances to test, and unfortunately, two are white! "Let's heat them!" suggested Donna.

Did Donna have a reasonable solution to their problem?

Accepted Answer

Yes, sugar's melting point is much lower than the other four solids.

Answer

No, it's impossible to reach these temperatures in a student lab.

Answer

No, all four substances have pretty low melting points.

Answer

Yes, it would help narrow the search to salt or sugar.

Question 18

As matter changes state from gas to liquid, which of these statements is true?

Accepted Answer

The particles slow down.

Answer

The attractive force between the particles decreases.

Answer

The particles speed up.

Answer

The particles get farther apart.

Question 19

Which is the MOST accurate statement about the heating curve and energy?

Accepted Answer

Moving from A to C the temperature and the kinetic energy increases.

Answer

As time elapses, the substances turns into plasma and has the highest kinetic energy.

Answer

Although the temperature increases, there is no information about energy change.

Answer

Moving from C to A the temperature decreases but the kinetic energy increases.

Question 20

A truck's tires have the correct air pressure at room temperature (about 20oC). During long trips, the tire of a truck may reach extremely high temperatures. Why are the tires more likely to explode when the truck is driven in hot weather than in cold weather?

Accepted Answer

The volume isn't really changed, but the pressure increases due to the extreme heat causing the tire to explode. The cold weather causes the tire to deflate needing air added to it.

Answer

The tire will explode in heat due to the rising volume in the tire, which melts some and then explodes.

Answer

The volume increases a lot in the cold, causing the pressure to increase. In the heat pressure decreases so much that it causes the tire to deflate, and the metal in the car pops the tire.

Answer

The volume isn't really changed, but the pressure decreases due to the extreme heat causing the tire to need more air. The cold weather causes the tire pressure to increase causing it to explode.

Question 21

Using the graph, what is happening to the particles of benzene in the horizontal section of the line, between state C and state B?

Accepted Answer

Thermal energy is being added to make particles move faster until break free from positions.

Answer

Thermal energy is being removed to make particles move faster until they are free from position.

Answer

Thermal energy is being removed to make particles slow down to become a fixed position.

Answer

Thermal energy is being added to rearrange particles into a fixed position.
