Answer 1

1) The last state of matter we will study is gases.

a) P for Pressure which is often measured in units of atmospheres (atm), milliamps (mm Hg), pounds per square inch (psi), pascals (Pa)

b) V for Volume which is often measured in units of liters (L), cubic meters (m3), cubic feet (ft3), cubic inches (in3)

c) T for Temperature which must be in units Kelvin (K) or Celsius (°C).

d) n for Number of moles , which is often found by converting from grams of a gas.
