Why do liquids take the shape of their container? Why do gases condense when they are cooled? Why do liquids flow? Why are liquids usually difficult to compress? Explain why water vapor turns into a liquid as it cools. Why does temperature increase when water condenses?
2. Properties of Liquids and Gases: - Liquids and gases do not have a fixed shape. They take the shape of their container. - This lack of a fixed shape means that they do not have defined lengths or areas that can expand in a linear or superficial manner. 3. Cubical Expansion: -...
Why do liquids take the shape of their container? What properties are important in liquid-liquid separations? How does evaporation differ from vaporization? How are evaporation and sublimation similar? How are rocks and minerals alike? Why is the volume of an ice cube is greater compared to when...
We design and manufacture world-class gas analysis systems and emission monitoring solutions to measure gaseous emissions from industrial processes, gases released from natural sources into the atmosphere, and gases present in working environments. We contribute to keeping people safe and the environment ...

In an electrolyzer, you place a solution in a container and dip two terminals into it. You connect the terminals up to a battery or other power supply and pass electricity through the solution. Chemical reactions take place and the solution splits up into its atoms. If the solution you use...
Distillation goes a step further than ordinary boiling: you boil water to make steam, then capture the steam and condense (cool) it back into water in a separate container. Since water boils at a lower temperature than some of the contaminants it contains (such as toxic heavy metals), ...
use a reusable container. Which cuts off the litter and stops the animals from getting hold of it. It can be hard to reuse, particularly if you live in a herd-like community of shared living. Some people might not be enthusiastic about the world, but you may have to take on more resp...
Gas pressure is achieved via the collisions of molecules with the walls of a container. True or false? Gas molecules are greatly attracted to each other. True or false? Gases have a definite shape. Pressure depends on how many gas particles are i...
Some chimney pipes have a T-shape, with a crosspiece on top that helps draw up gases whenever there is even a slight breeze. Explain how this works in terms of Bernoulli's principle. At what wind speed (in m/s) does -20 degree C air cause the same chill factor as still air at ...
