Part A: For calculations involving gaseous systems, it is important to use the kelvin temperature scale.
What is the temperature in kelvin if a thermometer reads 221 °C?
Part B: If we are given the temperature in Kelvin, we may need to turn this back into Celsius (most thermometers use the Celsius scale).
A gas has a temperature of 286 K. What is this temperature in Celsius?

- Oil Ethanol and Water Water A student combines equal volumes of ethanol and water in a beaker and stirs the mixture. The student repeats this process but with equal volumes of oil and water in a different beaker. The student observes the contents of the beakers after they are mixed, as shown in the diagram. Which TWO of the following statements are consistent with the student's observations? Ethanol molecules and water molecules are both polar, so they mix well with each other. Ethanol molecules are nonpolar and water molecules are polar, so they mix well with each other. Oil molecules and water molecules are both polar, so they do not mix well with each other.
