Pl help Plan a controlled experiment to investigate how much the temperatures of cold sand and cold water change when hot
water is added to them. Assume you have access to water, sand, containers, ice, a heat source, a scale, and
thermometers. Summarize your experiment in a few sentences.

periodic trends is an atom that gets larger as the number of electronic shells increase, the radius of atoms increases as you go down a certain group in the periodic table of elements. in general, the size of an atom will decrease as you move from left to right of a certain period.

the volume increases

the electron configuration that you gave me has 16 electrons ergo it has 16 protons ergo it is the element sulfur.

i believe the answer is true.
