Which description best fits a gas? definite shape and volume; strong intermolecular attractions definite volume; shape of container; moderate intermolecular attractions definite volume; shape of container; weak intermolecular attractions volume and shape of container; no intermolecular attractions volume and shape of container; strong intermolecular attractions?

Gas particles has weak intermolecular force of attraction and takes shape of the container.

Weak intermolecular attractions volume and shape of container is the statement best fits with a gas because gas molecules are present at a distance from each other and move freely due to weak intermolecular force of attraction.

Gas molecules has no definite shape and no definite volume. It takes the shape of the container and can be collected into a container with higher pressure so we can conclude that gas particles has weak intermolecular force of attraction and takes shape of the container.

The answer is weak intermolecular attractions volume and shape of container. The molecules of gases have high kinetic energy compared to those of liquids and solids hence they are farther apart from one another. This results to weak intermolecular forces. Gases also expand to fit the container hence have no definite shape or volume.

c. because step up transformer steps up the input voltage i.e increases the input voltage  

the number of turns are greater on the secondary side of step up transformer  

transformer does not handle dc current

indicate valleys, hills, steepness and gentleness of slopes.

explanation:

contour lines on a map indicate elevation, or depth. numeric notations on contour lines refer to the level of elevation, or height about sea level.
