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 balloon's mass increases because the size of the balloon increases.

• The balloon's mass increases because the temperature of the balloon has increased.

• The balloon's mass stays the same because the gas inside the balloon still has the same mass

• The balloon's mass 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 they 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 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.
