Matter, Volume, Density

Master matter, volume, and density! Learn to calculate and predict sink or float.

Part 1: Matching 3Match the unit with the measurement grams mass mL or cm3 volume g density The definition ofmassis the amount of matter in a given volume the amount of matter in an object the amount of water in an object To find the volume of an irregular object like a rock, you would use a graduated cylinder and get the the formula l x w x h water displacement (the difference in the graduated cylinder with just water and the graduated cylinder with the rock in it) a ruler M = 66 g; V = 22 ml D = 44 g D = 3 g D = 88 g D = 4 g Volume Question Use the image above to answer the following:A student needs to determine the volume of an irregular object. The original volume of water is 4.8 mL. The student then drops the object into the graduated cylinder and determine the new volume to be 5.6 mL. What is the volume of the object based on the water displacement? 4.8 mL 5.6 mL 1.2 mL 0.8 mL A student found the rock shown below and used a digital scale it to determine it's mass. After getting the mass of the rock above, what steps should the student take to find its density? determine its volume by how much water it displaces, then divide mass by volume determine its volume by multiplying length x width x height, then divide mass by volume crush the rock to a powder, measure its volume in a graduated cylinder, then divide mass by volume If a wooden block were cut into eight identical pieces, the density of each piece compared to the density of the original block would be less greater the same Water has a density of 1 g If two solid objects with the following densities were placed in water, what will happen?Object A - Density = 0.8 g Object B - Density = 1.2 g.cm3 Both objects will sink Both objects will float Object A will float, and Object B will sink Object B will float, and Object A will sink If an object's mass is 9 g and it displaces 3 mL of water, what is its density? 6 g 12 g 3 g When you have objects made of the exact same stuff, they have the same chemical change density mass volume You have 2 pieces of silver. Piece one has a mass of 5 g, and piece 2 has a mass of 10 g. Which is more dense? Piece 1 Piece 2 They are the same since they are both made of only silver There is no way to tell If a sample's volume is 56 mL and its mass is 784 g, its Density is - 728 g 14 g 840 g 43, 904 g If you have one type of rock that has the same mass as another type of rock, what can you conclude. They have the same density They have the same volume You can't know if they have the same density until you get the volume first and use it in your formula d=m Predict whether the following items will sink or float in fresh water. Click on each item, then choose sink or float to place it in the correct column. SINK gold 19.3 g corn syrup 1.38 g FLOAT ice .92 g corn oil .93 g wood .85 g Mass of 1000 grams, volume of 250 ml 5 g 3 g 4 g 2 g Calculate the mass using a triple beam balance YOU MUST PUT THE UNIT OF MEASUREMENT (g) 190.4g 37.3g 105.6g Sort the descriptions and measurements by matching them to the appropriate tool. Balance Measures mass Grams Graduated Cylinder Measure from the bottom of the meniscus Measures volume mL or Milliliters Ruler Measures length Feet, inches, cm, meters meters
