Intro to I.S. santos

santos PNHS intro to I.S. vocab

What state of matter has a definite shape and a definite volume? Give an example. The state of matter that has a definite shape and definite volume is solid. An example is a wood log.
What state of matter takes the form of the container it is held in? Liquid is the state of matter that takes the form of the container it is held in.
What is kinetic energy? Give an example. Kinetic energy is the energy an object has due to its motion. The faster an object moves, the greater its kinetic energy. An example is a baseball thrown from a pitcher.
What is gas pressure and how does temperature, volume, and number of particles affect it? Gas pressure is the pressure from gas when something collides with another object. Temperature makes the gas faster and increases the pressure. By decreasing the volume, the pressure increases. If you add particles, then the pressure gets greater.
What is the difference between Charles's law and Boyle's law? Charles's law says that the volume of a gas is directly proportional to its temperature in kelvins (if pressure and # of particles are constant). Boyle's says if the volume decreases, speed increases.
