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

After a rain, a puddle of water remains on a sidewalk. After a day of sunshine, the puddle is gone. Which process is most responsible for the disappearance of the puddle?

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