Density Exam Review
If you placed a 15 cm 3 sized object into 20 mL of water, how much water will be displaced? 15 mL of water
A cube of clay has a density of 1.20 g/cm 3, if a 25 gram cube of clay was cut in half, what would be the density of each of the pieces? 1.20 g/cm 3 = Density DN change!!
If you see the SI units of grams, what parameter does this represent? MASS
If you see the SI units of mL, what parameter does this represent? Volume of a Liquid
If you see the SI units of cm 3, what parameter does this represent? Volume of a Solid
If you see the SI units of g/cm 3, what parameter does this represent? Density of a Solid If you see the SI units of g/mL, what parameter does this represent? Density of a Liquid
Maple Wood (D = 0.669 g/cm 3 ) Granite (D = 2.163 g/cm 3 ) Tungsten (D = 18.80 g/cm 3 ) All three were thrown into water, which would float? Maple Wood Which would sink? Granite & Tungsten
Your swan ice sculpture is approximately 250 cm 3 in size. If the density of ice is 0.9167 g/cm 3 then what is it’s mass? M = Dv = (0.9167 g/cm 3 )(250 cm 3 ) = 229.18 g
A piece of copper was found to have a mass of 117 g - what is it’s volume? D = 8.96 g/cm 3 V = m/D = 117 g / 8.96 g/cm 3 = 13.06 cm 3
A object has a mass of 25.00 g and a volume of 10 cm 3 - what is the object made out of? D = m/v = 25 g / 10 cm 3 = 2.5 g/cm 3 = GLASS
Which has more mass? A) 1 kilogram of feathers B) 1 kilogram of bricks
IPC Notes Density. density – the mass of an object per unit volume ex) the density of a substance describes how tightly packed the molecules are.
Chemistry Notes Density. density – the mass of an object per unit volume ex) the density of a substance describes how tightly packed the molecules are.
Density, Mass, Volume. Mass The amount of matter in a substance. Solids, liquids and gases have a mass. Measured with a balance Triple Beam
Density & Graphing Review Sheet Answers
Density. What is It? Derived unit which shows the mass per unit of volume More dense materials are “heavier” than less dense materials Density compares.
Objective: To calculate density.. - Volume of a cube or block = length x width x height - Volume of irregular shaped object = use water displacement.
A Look at Density and How to Calculate It.
Density, Time and Temperature
Density. Density is the mass of a given object over a unit of volume Density is an intensive property The formula to solve for density is D=m/V.
Density All substances have different densities, therefore, you can identify a substance if you know its density The formula to calculate something’s density.
Density Type of Units, Formula, Solving Density Problems.
Density Density describes how heavy an object is compared to its size.
