Why might a small increase in the demensions of an object cause a large change in its volume?
A small increase in the dimension increases the volume dramatically because the increases are all multiplied by each other. A balloon is a great example of volume increasing rapidly.
What happens to the atmospheric pressure acting on the balloon as the balloon rises?
due to pressure inside the balloon, will be higher because the balloon will try to get smaller and thus the balloon will ascent due to the low density of the helium inside the balloon.
How does a balloon pilot use density to control the altitude of a balloon?
the pilot heats the air stored in the balloon with a large flame the hotter it gets the higher it goes because the heat changes the density to make it go up or down if the pilot decreases the size of the flame the hot air lowers because the smaller flame has less heat giving it a higher volume, but the air stays the same thus making it lower
What is the difference between a water balloon and a normal balloon?
A water balloon is filled with water, and other balloons are filled with air or helium.
