Can a gas be returned to a liquid?
Yes. The three common phases of matter, solid, gas and liquid can be achieved by any material provided the right conditions, but different materials exist in different phases under the same conditions. The most common way that changes between these phases are achieved is by a change in temperature (although a change in pressure will also affect the state of matter). If a gas is cooled sufficiently, it will form a liquid. For example, if you set a glass of ice-water out, the outside of the glass will become wet. This wetness is water vapor which was in the air as a gas, but was cooled when it came into contact with the cold glass and condensed on the glass into a liquid. Even gases like Nitrogen, which makes up most of the air around us, can form a liquid, although it must be cooled to −196 °C.

What role should top management play in the change process?
At all phases of the change process, top management representatives must strongly support the change processes and communicate that support to the work force.
What phase of matter has no definite shape?
liquid, gas, and plasma phases must be contained to remain in the same shape. Solid retains it's shape without containment.
What must you do to a substance to get it to change its state of matter?
That is done by either heating or cooling.
