  1. 2. The reduction in volume of a substance using a mechanical force
  2. 4. The difference in pressure between that of the substance and standard atmospheric pressure (psig)
  3. 5. When matter becomes dispersed we say it does this (begins with a D)
  4. 6. Temperature point above which a gas cannot be condensed by raising its pressure
  5. 11. The transition of a substance directly from the solid to the gas phase, without passing through the intermediate liquid phase.
  6. 12. The capacity of a physical system to perform work (measured in units called Joules)is known as this
  1. 1. The amount of space that a substance or object occupies, units cubic metres (cubic feet)
  2. 3. The physical force exerted on a substance by a fluid in contact with it, measured units Pascal (bar abs, psia)
  3. 7. This is a gauge used to measure very low pressures, sometimes called a vacuum gauge
  4. 8. Process we use to ensure measuring equipment is accurate
  5. 9. The name for the heat required to convert a solid into a liquid or vapour, or a liquid into a vapour, without change of temperature
  6. 10. This valve controls the amount of refrigerant released into the evaporator, sometimes called a metering device
