Challenge: Looking at the phase diagram...Water boils at approximately 100 degrees Celsius in Los Angeles, would it boil at a higher, lower, or the same temperature in Denver, Colorado? Please explain your answer

the density(ratio between mass and volume as m/v) decreases from top to bottom in periodic table group as the size increases and nuclear charge decreases. but in periods density increases from left to right as atom size decreases and nuclear charge increases.

the answer is c i took the test

it's c (engineer's do their work with mechanical stuff not on any living being)
