Consider the cooling curve above. The substance is changing state from a gas to a liquid to a solid. As the temperature changes
Anni [7]

Answer: B)  there is a decrease in kinetic energy and the molecules get closer together.

Explanation: Kinetic energy is directly proportional to temperature, thus as temperature decreases, kinetic energy also decreases.

Gas is the state of matter in which particles are very loosely bound and hence can easily move past one another very easily and have highest kinetic energy.

Liquid is the state of matter in which particles are loosely bound and hence can move past one another easily and have high kinetic energy.

Solid is the state of matter in which particles are tightly bound and hence can not move easily and have low kinetic energy.

Thus on moving from gaseous to solid state, the kinetic energy decreases and the molecules get closer together.

3. Roads in urban areas are generally
vovangra [49]

Answer:

parallel and intersect at right angles

Explanation:

The roads in the urban areas tend to be very well organized and constructed. They tend to be parallel to each other, and also to intersect at right angels. The reason for this kind of building of the roads in the urban areas is to make the movement in the urban areas much easier and more efficient, mostly putting the accent on the traffic. It is a fact that the traffic is a big problem in the urban areas, so by constructing the roads in a well organized manner, the traffic jam eases up and the citizens can move more easily and quickly.

During respiration, members of the animal kingdom use ______ and then release ______ as a waste gas
raketka [301]

During respiration, members of the animal kingdom use oxygen and then release carbon dioxide as a waste gas.

Members of the animal kingdom have a respiratory system that is composed of muscles, and airways that functions together to transport air into lungs, and the oxygen is used by cells. Carbon dioxide is also transported away from the cells as a waste gas. Respiration relies on other systems, such as the circulatory system, to transport oxygen and carbon dioxide to and from cells.
