What changes would occur at a molecular level if a liquid is placed in cool conditions?

Dafna1 [17]

Answer: Option (C) is the correct answer.

Explanation:

Movement of particles in a substance is responsible for change in state of the substance or matter.

This means that more is the motion of particles more will be their kinetic energy.

Also, kinetic energy is directly proportional to temperature.

K.E = $\frac{3}{2}kT$

So, less is the temperature of an object or substance less will be be the motion of its particles. Therefore, molecules will come closer to each other and state of substance will change from liquid to solid.

Thus, we can conclude that the motion of the molecules would decrease at a molecular level if a liquid is placed in cool conditions.

This means that the four substances, even they are used in different areas like gardening, plastics or pots, all of them change the endocrine system in humans because they imitate the natural hormones and the body stops to produce them or starts to produce more hormones than the body needs.

They are correlate with some illness like cancer, thyroid problems and infertility.

4. Explain error and how it can impact your results from an experiment

Jet001 [13]

Random errors will shift each measurement from its true value by a random amount and in a random direction. These will affect reliability (since they're random) but may not affect the overall accuracy of a result.
