How will this relationship between volume and pressure affect a long, skinny balloon that is twisted into the shape of an animal?
As the balloon is twisted and volume of the space in which the air is contained is reduced, the pressure will increase.
400
What is the relationship between the volume and the pressure of a gas when the temperature is held constant?
The volume is inversely proportional to the pressure when the temperature is constant.
400
The volume of gas is related to its pressure. Pressure must be constant. This is _______________________ law?
Charle's law

How is it possible to make a solid metal container in the shape of a pan?
The metal is melted so that it will flow and then put into a mold in the shape of a pan. There it cools and freezes so that it holds the shape of the mold.

A container with a mixture of water and ice is a 0 degree C. What will happen if energy is added to or removed from the water?
If energy is added, the ice will melt, and if energy is removed, the water will freeze.
