Answer the following question given this paragraph: In the above equation for pressure, force is expressed in Newtons (N) and area is expressed in square meters (m 2 ). Therefore, pressure is expressed in N/m 2 , which is the SI unit for pressure. This unit is also called the Pascal (Pa) . It is named for the scientist Blaise Pascal whose discoveries about pressure in fluids led to a law of the same name. Pressure may also be expressed in the kilopascal (kPa), which equals 1000 Pascals. For example, the correct air pressure inside a mountain bike tire is usually about 200 kPa. Q: What unit of pressure is named for the scientist whose discoveries about pressure in fluids led to a law of the same name? Choices: - ohm - newton - joule - pascal A:
(Answer)
pascal
Ques: Answer the following question given this paragraph: Condensation changes water vapor to liquid water. As air rises higher into the atmosphere, it cools. Cool air can hold less water vapor than warm air. So some of the water vapor condenses into water droplets. Water droplets may form clouds. Q: What changes water vapor to liquid water? Choices: - fermentation - global warming - combustion - condensation A:
Ans: condensation
