temperature of a gas?. Answer: combines gas law
◉ The relationship between the pressure and volume of a sample of
a gas constant temperature is a?. Answer: inverse proportion
,◉ The device used to measure blood pressure?. Answer:
sphygmomanometer
◉ used to measure atmospheric pressure. Answer: barometer

◉ What did the Emancipation Proclamation do?. Answer: found that
atmospheric pressure at the top of a mountain is less than it is at the
bottom of the mountain.
