Heating a substance causes molecules to speed up and spread slightly further apart, occupying a larger volume that results in a decrease in density. Hot water is less dense and will float on room-temperature water. Cold water is more dense and will sink in room-temperature water.

Answer:

Quite Stable

Explanation:

The <em>density of liquid water is very  stable and varies little with changes in  temperature and pressure .</em>

At the normalized pressure of 101 325 Pa (1 atmosphere), the  liquid water has a maximum density  999,974 9 kg · m-3 at 3,983 035 ° C. When climbing  the temperature decreases the density (by  For example, at 20 ° C it has 998,206 7 kg · m-3 and at  40 ° C reaches a density of 992,215 2  kgm-3.

The temperature of 3,983 035 ° C represents a turning point and is when it reaches its maximum density (at the mentioned pressure). From that point, when the temperature drops, the density begins to decrease, although very slowly  (almost nothing in practice), until at 0 ° C it decreases until  999,842 8 kgm-3.

Mary Beth bought 15 ghost shrimp. She put 5 in a small fish bowl, 5 in a larger tank, and 5 in an artificial pond in her backyar
Kaylis [27]

Answer:

Initial age of ghost shrimp and water temperature

Explanation:

In an experiment, there are several variables (alterable factors) that determine the outcome of the experiment. A CONTROLLED variable or CONSTANT is a variable that is kept constant or unchanged throughout the experiment. The constant is not changed because it can affect the other variables (outcome) of the experiment.

For this experiment conducted by Mary Beth on the effect of size of the tank on the size of the shrimp after 6months, the constants are INITIAL AGE OF GHOST SHRIMP and WATER TEMPERATURE. This is so because the ghost shrimps of the same initial age must be used to start the experiment, so as to be able to measure the actual effect on the growth. Also, the water in the respective tanks must be the same Temperature so that one experimental group will not be favored over another.

erica [24]

Answer:

The correct answer is "biomedical model"

Explanation:

The biomedical model is an approach that looks to understand the biological functions under normal and abnormal circumstances. A researcher who describes illness solely in terms of biological causes and factors is using a biomedical model. This model is a scientific approach to fight diseases which is very helpful for the development of new therapies, however it could result in confusion particularly if it is used to explain the disease to a patient.
