Answer:
Phase changes typically occur when the temperature or pressure of a system is altered. When temperature or pressure increases, molecules interact more with each other. When pressure increases or temperature decreases, it's easier for atoms and molecules to settle into a more rigid structure.

Explanation:
The following observation would be included in a hypothesis: a connection between type of material and thermal energy transfer is developed (option C).
<h3>What is a hypothesis?</h3>
Hypothesis is a tentative conjecture explaining an observation, phenomenon or scientific problem that can be tested by further observation, investigation and/or experimentation.
The hypothesis is regarded as an educated guess because it predicts the possible outcome of an experiment.
The hypothesis is a statement that relates the independent variable of the experiment with the measured or dependent variable.
Therefore, the following observation would be included in a hypothesis: a connection between type of material and thermal energy transfer is developed.

The oceanographers define salinity by the number of grams of salt per kilogram of water.
Salinity is illustrated as how much salt is present in the given amount of water. It is dependent upon how much salt is found in the ocean in the specific regions. If there is a sunny environment, it may evaporate an ample amount of water, and leave behind a lot of salt, thus, the water has more salinity.
The salinity of the ocean is usually measured in Practical Salinity Unit (PSU), it is a unit based on the characteristics of seawater conductivity.
Answer:
False
Explanation:
Polar molecules and ionic compounds dissolve in water, not nonpolar molecules
