Final answer:
Air pressure is represented in pascals, millimeters of mercury, millibars, and atmospheres. Temperature is measured in Celsius, Kelvin, and Fahrenheit degrees. The dew point is measured in Celsius and Fahrenheit degrees.
Step-by-step explanation:
The air pressure is represented in options a) pascals, b) millimeters of mercury (mm Hg), c) millibars, and d) atmospheres. These are all commonly used units to measure air pressure. For example, standard atmospheric pressure at sea level is about 1 atmosphere (atm), which is equal to 760 mm Hg, 101.3 kilopascals (kPa), or 14.7 pounds per square inch (psi).
The temperature is measured in options a) Celsius degrees, b) Kelvin degrees, c) Fahrenheit degrees, and d) Rankine degrees. In gas laws, it is important to always express temperatures in Kelvin (K). Celsius (°C) and Fahrenheit (°F) are commonly used scales for everyday temperature measurements.
The dew point is measured in options a) Fahrenheit degrees, b) Kelvin degrees, c) Celsius degrees, and d) Rankine degrees. The dew point is the temperature at which air becomes saturated with water vapor. It is typically expressed in Celsius (°C) or Fahrenheit (°F).
