5 Multiple Choice Questions
- A characteristic of almost all matter that causes it to expand when heated and contract when cooled
- the amount of energy needed to change a liquid to a gas
- Water that contains high levels of unwanted substances that may be harmful to living things.
- when electrical generating plants or industries release large amounts of heated water into rivers; excess heat in water
- Fluids flow faster through narrow spaces. As a result the speed increase, the pressure of the fluid drops. This reduction in pressure in these spaces is a special case of Bernoulli's principle Ex- baseball
5 True/False Questions
buoyant force- buoyancy → the force is the ability of a fluid-liquid or gas- to exert an upward force on an object immersed in it. (float)
states of matter → solid, liquid, gas, and plasma; state of a sample of matter depends on the temperature
Bernoulli's Principle → as the velocity of a fluid increases, the pressure exerted by the fluid decreases Ex- Coca Cola bottles
amorphous solid → the process where a liquid changes to a gas gradually at temperatures below the boiling point.
sublimation → when a solid goes to a gas
