Across
- 2. term used to describe a reaction or process that releases energy in the form of heat
- 5. is a unit of thermal energy equal to 4.184 joules or the amount of energy required to raise the temperature of 1 gram of liquid water 1°C at standard pressure.
- 6. The change in enthalpy for the conversion of 1 mole or 1 gram of a solid to a liquid, at constant pressure and temperature and is usually denoted as ΔHfus.
- 9. change in the state of matter from the gas phase to the liquid phase.
- 11. the settling of particles or sediment onto a surface. The particles may originate from a vapor, solution, suspension, or mixture; also refers to the phase change from gas to solid.
Down
- 1. is the basic SI unit of energy
- 3. is the state of a chemical reaction when the concentrations of the products and reactants are unchanged over time.
- 4. is the point at which two phases of a substance initially become indistinguishable from one another
- 7. (ΔHRXN)
- 8. may be defined as the ability to do work. It is a scalar physical quantity. Although it is conserved, there are many different types of energy, such as kinetic energy, potential energy, light, sound, and nuclear,
- 10. describes a process which absorbs thermal (heat) energy.
