Properties of Matter

QuestionAnswer
What is Archimedes' principle? A principle that states that the force exerted on an object in liquid is equal to the weight of the fluid displaced by the object.
What is Boyle's law? Pressure and volume are inverseley related.
What is brittleness? A measure of material's tendency to shatter upon impact.
What is buoyancy? A measure of the upwared force a fluid exerts on an object.
What is Charles' law? The volume of gas increases with increases temperature if pressure is held constant. The volume of gas decreases with decreasing temperature.
What is Density? A property that describes the relationship between mass and volume.
What is elasticity? A measure of a solids's ability to stretch and then return to its original shape and size.
What is hardness? A measure of solid's resistance to scratching.
What is pascal? The SI unit of pressure.
What is one pascal equal to? One pascal is equal to one newton of foce actiing on one square meter of surface.
What is tensile strength? A measure of how much pullin, or tension, a material can withstand before breaking.
What is pressure? The force acting on an unit area of surface.
What is viscosity? A measure of a material's resistance to flow.
What is fluid? A material that flows, commonly refer to matter in liquid or gas state.
What is malleability? A solid's ability to be pounded into thin sheets.
What is an example of highly malleable metal. Aluminum.
What makes an object float? If the buoyant force is greater than its weight.
What makes an object sink? If the buoyant force is less than its weight.
What are examples of Boyle's law? As the pressure of gas increases, its volume decreases. As the pressure of a gas decreases, its volume increases.

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:
