- Q1An instrument used to measure atmospheric pressure is called a(n)thermometerbarometeranemometerhygrometer30s
- Q2Suppose gas molecules inside a box are held at the same temperature. As the volume of the box increases, the pressure _____decreasesincreasesstays the samenot enough information30s
- Q3Bernoulli's Principle Statesthe buoyant force is equal to the volume of air displacedas the speed in fluid increases, the pressure increasesas the speed in fluid increases, the pressure decreasesas the speed in fluid decreases, the pressure decreases30s
- Q4The upward force exerted between different air pressures is known asLiftEddiesBoyle's LawStreamlines30s
- Q5Boyle's Law StatesP1V2 = P2V1V2/P2 = P1V1P1V1 = P2V2P1/V1 = P2/V230s
- Q6Boyles Law States thatthe product of pressure and volume for a given mass of of gas at constant temperature is constantthe quotient of pressure and volume for a given mass of of gas at constant temperature is constantthe sum of pressure and volume for a given mass of of gas at constant temperature is constantthe different of pressure and volume for a given mass of of gas at constant temperature is constant30s
