Physics Quiz - Density
 1. The measure of how close and how heavy are the particles in an object is called its:A massB weightC density 2. The rule to calculate density is:A weight X volumeB mass / volumeC volume / weight 3. The density of water in g/mL is:A 0B 1C 10 4. One millilitre has a volume of:A one cubic centimetreB one teaspoonC 1/10 cubic metre 5. A substance whose density is greater than 1 g/mL will:A floatB be suspendedC sink 6. The density of a feather in g/mL would be about:A 10B 0.05C 0 7. The density of ice in g/mL is:A less than 1B 1C more than 1 8. The density of petrol in g/mL is about:A 0.7B 1C 3 9. An object is suspended in each of two full containers, one containing water and the other petrol. In which container will the object be higher in the liquid?Athe same in both liquidsBwaterCpetrol 10. If a sinker made of lead and another identical sinker made of aluminium were dropped into saltwater, why would the lead sinker reach the bottom first?: Athe aluminium sinker has a greater surface area Bthe density of lead exceeds that of aluminium Cthe lead sinker is more aerodynamic 11. A density of 2 g/mL is equal to a density of: A20 grams per cubic centimetre B0.2 kilograms per metre C2000 kilograms per cubic metre 12. An object has a mass of 10 grams and a volume of 5 ml. What will happen when the object is placed in water, and why? ASink slowly, because the density of 2 g/mL is greater than that of water BSink quickly, because the density of 50 g/mL is much greater than that of water CFloat, because its density is 0.5 mL/g which is less than that of water 13. A stone has a mass of 200 grams. When it is immersed in a measuring cylinder of water, the water rises 100 millilitres. What is the density of the stone? Ainsufficient information given B0.2 kilograms per cubic metre C2 grams per millilitre 14. The least dense gas is: Anitrogen Bhelium Chydrogen 15. The density of carbon dioxide gas is greater than that of air. In a container of air, carbon dioxide gas will be found: Aat the bottom of the container Bmixed evenly throughout the container Crisen to the top of the container
