| Question | Answer |
|---|---|
| How can a solid be defined? | Matter in the solid state has both a definite volume and a definite shape. |
| How can matter in a liquid state be defined? | matter in the liquid state has a definite volume but no definite shape, taking the shape of whatever container it is placed in |
| How can the gaseous state of matter be defined? | matter in the state of gas has neither a definite volume nor a definite shape and expands to fill any container. |
| What is kinetic energy? | Kinetic energy is energy of motion. The kinetic energy of an object is the energy it possesses because of its motion. |
| It it easier to use the pressure or force to describe the influences on fluid behavior? | Pressure is defined as force per unit area. It is usually more convenient to use pressure rather than force to describe the influences upon fluid behavior. |
| What is absolute zero? | Absolute zero is the lowest possible temperature where nothing could be colder and no heat energy remains in a substance. |
| What does the Charles's Law suggest? | Charles' law is a special case of the ideal gas law where the pressure of a gas is constant. Charles' law states the volume is proportional to the absolute temperature of a gas at constant pressure. |
| Describe the Boyle's Law. | Boyle's Law is a principle that describes the relationship between the pressure and volume of a gas. |
| what is a phase change? | Transitions between solid, liquid, and gaseous phases typically involve large amounts of energy compared to the specific heat. |
| exothermic | a process that releases energy in the form of heat. |
| endothermic | a process or reaction that absorbs energy in the form of heat |
| Identify the heat of fusion. | The energy required to change a gram of a substance from the solid to the liquid state without changing its temperature is commonly called it's "heat of fusion". |
| Explain heat of vaporization. | The amount of heat required to convert unit mass of a liquid into the vapor without a change in temperature. |
| What is sublimation? | Sublimation is the process of transformation directly from the solid phase to the gas phase without passing through an intermediate liquid phase. |
