Which best explains why a hot air balloon floats?

• The heated air expands to fill the balloon. The air in the balloon is now lighter than the surrounding air, causing the balloon to rise.
• The heated air expands to fill the balloon. The air in the balloon is now heavier than the surrounding air, causing the balloon to rise.
• The heated air contracts to fill the balloon. The air in the balloon is now denser than the surrounding air, causing the balloon to rise.
• The heated air contracts to fill the balloon. The air in the balloon is now lighter than the surrounding air, causing the balloon to rise.

A student places a cup of cold water on a counter in a hot room.   After a short time, the student notices that the water in the cup is no longer cold.  Which best explains why the water in the cup is no longer cold?

• The coldness of the water transferred to the air, making the water in the cup warmer.
• The coldness of the water was conducted to the cup, making the water in the cup warmer.
• The heat from the air transferred to the water in the cup, making the water in the cup warmer.
• The heat from the air caused the cold water in the cup to condense, making the water warmer.
