True and False: If the statement is true, write "true." If it is false, change the underlined word or
words to make the statement true. Write your answer on the line provided.
1. Real gases behave like ideal gases except at very high temperatures.
2. The gas constant, R, is equal to 0.0821 when the pressure is expressed in
kilopascals.
3. As more gas particles are added to a container, there are fewer collisions
because the particles don't go as far.
4. The number of moles of a gas is inversely proportional to its volume at
STP.
5. Real gases behave like ideal gases except at very high pressure.
6. At a constant temperature, the pressure exerted by one mole of a gas
decreases if the volume available is increased.
7. The ideal gas equation will only give correct values if the temperature in
expressed in degrees Celcius.
8. One mole of oxygen at 760. mm Hg and 0 °C occupies a volume of one L.
