If you are working with an irregular objectsuch as a rock or a mineral, howdo you determine its volume? use a triple beam balance Water displacement use an electronic balance L X W X H Remember,Radiant is light and acoustic is soundenergy. A. nuclear and electrical B. magnetic and mechanical C. radiant and electrical D. acoustic and mechanical A. conduction B. convection c. absorption d. radiation A student on a field trip was required to calculate thedensity of a mineral containing rock.The rock had a volumeof 90 mL and a mass of 450 grams. What is the density of the rock? 360 g/mL 5 g/mL 0.2 g/mL 540 g/mL Why do some substances float in water? They are warmer than water they are cooler than water They are less dense than water They are more dense than water A student measures themass of a mineral sampleusing a balance. It is 125 grams. Shethen places the item in the graduated cylinder containing water as shown below. What is the density of the mineral? 4 g/cm3 3 g/cm3 5 g/cm3 6 g/cm3 A substance has a volume of 20 cm3 and a mass of 54 grams.What is the density of the substance? 74 g/cm3 1080 g/cm3 0.37 g/cm3 2.7 g/cm3 A substance has a mass of 12.4 grams and a volume of 4 mL.What is it's density? 8.4 g/mL 3.1 g/mL 0.32 g/mL 49.6 g/mL The following measurements were made of an object.What information should you consider when discussing the object's density?1. When the object is placed on a balance it reads 3.7g2. The thermometer says the object is 27 degrees3. One side of the object is 2.0 cm long4. The water in the graduated cylinder rises from 35 to to 47 when the object is placed inside5. the object has a hardness of 3.5 on the Mohs Scale 1 and 2 2 and 3 3 and 5 1 and 4 Which category of elements may or may not be shiny, are semi-conductors, and may be brittle or malleable? metalloid metal nonmetal can't tell A student is working to create a circuit that lights up a lamp. She runs copper wire from a battery to a lightbulb. Why is copper the best choice of material for this circuit? it is brittle and ductile it is ductile and a good conductor it is shiny and solid it is malleable and insulates Samantha fills a graduated cylinder to the 30 mL mark. She places the mineral into the cylinder and it rises to 43 mL. What is the volume of the mineral 73 mL 13 mL 30 mL 43 mL Which of the following are properties of metalloids? gas at room temperature, poor conductor shiny, good conductor, malleable semi-conductor good conductor, brittle, On the Periodic Table nonmetals are found...... along the zigzag line to the right of the zigzag line to the left of the zig zag line they are not on the periodic table A student fills a graduated cylinder with 15mL of water. The lab partner finds the mass of the marble to be 2.21grams, then drops the marble into the graduated cylinder. If the meniscus on the cylinder is now at 16.3 mL, what is the density of the marble 1.7 g/mL 17 g/mL 0.58 g/mL 0.13 |
