Match the phase with its properties. Match the phase with its properties. [blank_start]Solids[blank_end] Have an indefinite shape, but a definite volume. [blank_start]Liquids[blank_end] Have an indefinite shape and an indefinite volume. [blank_start]Gases[blank_end]

Match the property with its definition. Brittleness How [blank_start]easily a substance will shatter or break[blank_end] Malleability How [blank_start]easily a substance can be shaped[blank_end] - e.g. hammer into flat sheets Tensile Strength [blank_start]Strength under stretching forces[blank_end]

Water Freezes at the same place, but depending on which scale you're using you will get a different degree reading for where it freezes. (Enter your answers with numbers, not words. E.g. write "1" instead of "one") On the Celsius scale, water freezes at [blank_start]0[blank_end] degrees On the Fahrenheit scale, water freezes at [blank_start]32[blank_end] degrees On the Kelvin scale, water freezes at [blank_start]273.2[blank_end] degrees

Calculate the volume of an object with a length of 2cm, a width of 7cm, and a height of 5cm in cm^3 Volume: [blank_start]70[blank_end] cm^3

It is impossible for anything in the universe to reach 0 Kelvin

Match the phases of matter with their particle speeds In a solid, particles are moving [blank_start]slowest[blank_end] In a liquid, particles are moving [blank_start]at a relatively moderate speed[blank_end] In a gas, particles are moving [blank_start]fastest[blank_end]

While exploring the remote jungles of the Amazon, you find a strange rock. It weighs 275 g and has a volume of 25 cm^3. Calculate the density and give your answers in g/cm^3. The density of the rock is: [blank_start]11[blank_end] g/cm^3

Calculate the density of an object with a mass of 2.5 kg and a volume of 5 L in kg/L Density: [blank_start].5[blank_end] kg/L

What are the relationships between Pressure, Volume, and Temperature As temperature increases, volume [blank_start]decreases[blank_end] As pressure increases, volume [blank_start]decreases[blank_end]

A fluid will always flow from an area of [blank_start]higher[blank_end] pressure to an area of [blank_start]lower[blank_end] pressure
