Across
- 1. the law that the product of the pressure and the volume of one gram molecule of an ideal gas is equal to the product of the absolute temperature of the gas and the universal gas constant.
- 3. the energy of motion, observable as the movement of an object, particle, or set of particles.
- 5. an experimental gas law which describes how gases tend to expand when heated.
- 6. A physical constant which is featured in many fundamental equations in the physical sciences, such as the ideal gas law and the Nernst equation.
- 9. a gas law, stating that the pressure and volume of a gas have an inverse relationship, when temperature is held constant.
- 12. A chemical reaction in which more energy is released than is required to break bonds in the initial reaction.
- 14. used when performing calculations on gases, such as gas density. The standard temperature is 273 K (0° Celsius) and the standard pressure is 1 atm pressure.
- 18. An insulated device that is used to measure the amount of heat released or absorbed during a physical or chemical process.
- 19. The heat content of a system at constant pressure.
- 20. The SI unit of heat and energy.
Down
- 2. States that in any chemical or physical process, energy may change from one form to another but it is neither created nor destroyed.
- 4. A law stating that the volumes of gases undergoing a reaction at constant pressure and temperature are in a simple ratio to each other and to that of the product.
- 7. the lowest temperature that is theoretically possible, at which the motion of particles that constitutes heat would be minimal.
- 8. mechanical energy, stored energy, or energy caused by its position.
- 10. A measure of the average kinetic energy of the particles in a sample of matter.
- 11. The volume occupied by one mole of a substance at a given temperature and pressure. It is equal to the molar mass (M) divided by the mass density (ρ).
- 13. A form of energy that flows from a warmer object to a cooler object.
- 15. The capacity to do work or produce heat; exists as potential energy, which is stored in an object due to its composition or position, and kinetic energy, which is the energy of motion.
- 16. A chemical reaction in which a greater amount of energy is required to break the existing bonds in the reactants than is released when the new bonds form in the product molecules.
- 17. The amount of heat required to raise the temperature of one gram of a given substance by one degree Celsius.
