6. You get to your dive site and park the car. You put on your gear and get ready to enter the water. But first you check your scuba tank. It is filled to a pressure of about 25,000 kPa at 300 K. The
volume of the tank is 25 L. You begin to wonder: If pressure remains constant, what would happen to
the volume of gas in the tank if its temperature increased? (6 points)
a. Which of the four thermal processes describes the temperature-volume relationship at
constant pressure? (3 points)
b. Write the equation for this process. Hint: Think about the first law of thermodynamics. (3
points)

Astone dropped into a well is heard to strike the water after 8seconds. find the depth of the well if the velocity of sound is 350m/s

What is the increase in density of a medium due to wave travel?

Researchers conducted an experiment to identify the effects of three different hand sanitizers on the growth of bacteria. the researchers grew one type of bacteria in twenty-four identical covered petri dishes. then, they opened eighteen petri dishes and applied the three hand sanitizers to six petri dishes each. they left the remaining six petri dishes closed as a control group. when the researchers measured the growth of bacteria two days later, the six dishes that had no hand sanitizer showed the least amount of bacterial growth. the researchers concluded that not using any hand sanitizer would lead to the least bacterial growth. which statement best explains why the researchers’ conclusion was not justified? the experiment tested too many variables. the control group was not treated the same as the experimental group. the sample size of twenty-four petri dishes is not large enough. the single type of bacteria is not adequate to make any conclusions.
