Which best describes the speed of a ball as it is thrown straight up into the air and

comes back down?

• The ball goes up at a constant speed, stops, then comes down at a constant speed.

• The ball goes up at a constant speed, stops, and increases speed as it comes down.

• The ball goes slower and slower as it goes up, stops, and then goes faster

  and faster as it comes down.

• The ball goes slower and slower as it goes up, stops, and then comes down

  at a constant speed.

made?

A student notices that an inflated balloon gets larger when it is warmed by a lamp.

Which best describes the mass of the balloon as a result of this change?

• The mass of the balloon increases because the size of the balloon has

  increased.

• The mass of the balloon increases because the temperature of the balloon

  has increased.

• The mass of the balloon stays the same because the gas inside the balloon

  still has the same mass after it warms up.

• The mass of the balloon stays the same because warming decreases the

  mass enough to cancel out the effect of increasing the size.

People sitting around a campfire are able to feel the heat from the fire. How are

the people able to feel the heat from the fire without touching the fire?

• The heat from the fire travels through the ground and heats the ground

  around the people.

• The heat from the fire is conducted through air molecules to the people.

• The heat from the fire rises in the air and then settles around the people.

• The heat from the fire radiates from the fire to the people.

Bill stands in a swimming pool and notices that the water around his feet is a lot

• evaporation

• radiation

• conduction
