Which two of the following could be used as evidence to explain the energy of the particles in the three cylinders?

• The energy of the particles in cylinder 1 is lower than the particles in cylinder 2.

• The particles in cylinder 2 move faster than in cylinder 3.

Which of the following would be the reason that students would use cellulose paper, foam, or wool to keep food from getting cold?

• To increase the heat loss through convection.

• To keep evaporation of the water from happening.

When emergencies take place around the world, blankets that look like Space Blankets are given out. They are shiny and made of a special material to help with keeping people warm. How would these blankets need to be made to help people in times of emergency?

• They need to conduct heat from persons near them to keep the wearer warm.

• They need to overheat people to get them back to their body temperature.

• They need to convect heat away from the body to keep it warm.

• They need to slow heat loss by reflecting body heat back to the wearer.

In a closed system, pressure is directly related to the kinetic energy of particles within the material. When pressure increases, it causes the particles to be forced closer together, which can result in a change of state. Which of the following is an example of when pressure causes a change of state?

• Gas condensing into a liquid under high pressure.

• Liquid evaporating into gas under high pressure.

• Ice melting into water under low pressure.

• Water boils at sea level.

If a student wanted to cause the change to take place from the first beaker to the third one, which of the following would need to take place?

• Put the sample at 0°C.

• Put the sample in the sun.

• Leave the sample out on the table.

• Heat the sample to 100°C.

If a student needs to show her classmates the law of conservation of mass, which setup would best help her to prove the law?

• Place water in a baggie, weigh it and place it in the freezer overnight then weigh it placing the bag and the ice onto the balance.

• Place water in a baggie, weigh it and place it in the freezer overnight then weigh it the next day by dumping out the ice onto the balance.

• Place water in a baggie, put it in the freezer overnight, then weigh the bag the next day.
