| Questão | Responda |
| A measurement of the energy content of a system | Enthalpy |
| When the forward rate of a chemical reaction is the same as the reverse rate. This only takes place in reversible reactions because these are the only type of reaction in which the forward and backward reactions can both take place. | Equilibrium |
| A measurement of the randomness in a system | Entropy |
| A biological molecule that catalyzes reactions in living creatures | Enzyme |
| It's the same thing as the Law of conservation of energy. | The First law of thermodynamics |
| The amount of heat required to increase the temperature of one gram of a substance by one degree. | Heat capacity |
| The temperature and pressure at which all three states of a substance can exist in equilibrium. | Triple point |
| A change that occurs by itself. | Spontaneous change |
| When a compound combines with oxygen gas to form water, heat, and carbon dioxide | Combustion |
| When the 3-D structure of a protein breaks down due to heat (or pH, etc), it's said to be denatured. This means that it unravels because the intermolecular forces between atoms in the chain aren't strong enough to hold it together anymore. | Denature |
| A chart which shows how the phase depends on various conditions of temperature and pressure. | Phase diagram |
| The state of a compound (solid, liquid, or gas) | Phase |
| When you boil a liquid. | Vaporization |
| When a vapor reforms a liquid. This is what happens on your bathroom mirror when you take a shower. | Condensation |
| It is a line graph that represents the change of phase of matter, typically from a gas to a solid or a liquid to a solid. | A cooling curve |
| When a solid can change directly into a gas. Dry ice does this. | Sublimation |
| Phase change | Phase transition |
| It is the physical process by which a protein chain acquires its native 3-dimensional structure, a conformation that is usually biologically functional, in an expeditious and reproducible manner. | Protein folding |
| It is the thermodynamic property of a system that changes by an amount equal to the work done on the system when it suffers an adiabatic change. It is the sum of the kinetic and potential energies of its constituent atoms, molecules, etc. | Internal energy |
| The pressure of a substance that's present above it's liquid. | Vapor pressure |
