Hot air is less dense compared to cold air. The heated air in the balloon will rise, making the balloon float in the air.to make it rise.
No. Remember that density is a ratio of mass compared to volume. If the volume increases without adding more mass, then the density would decrease. This is why hot air balloons rise.
Most substances expand when heated.
Matter usually expands when heated.

cheater! go ask mrs. s!
The same if it was closed (i.e cork). If it was open, it would be less, as gas usually expands as it is heated, and it depends on the amount of heat, the pressure, temperature etc.

The correct spelling is "figurative language." It refers to language that uses figures of speech, like similes, metaphors, and personification, to create a deeper meaning or visualization for the reader or listener.
In my experiment, he water with sugar had the most heat retention and cooled slower than the fresh water. I'm not 100% sure why, but I think it is because it is denser, therefore, when it is heated, more particles have been heated. If there are more particles heated, then it will take longer for each particle to cool down than water which has less particles.

well,.....for gas when it is heated the molecules spread and have power and become into vapor, and compared to liquid and solid it is larger because liquid is a not a solid and does not have a fixed shape, and a solid has a fixed shape and gas can be put into anything!
