Karten in diesem Stapel (9)
- 1Define density.the mass per unit volume of a substance
- 2What is: a) mass b) volumea) how much of something there is
b) how much space something takes up - 3What is the formula for density?density = mass / volume
- 4A wooden post has a volume of 0.025 m(3) and a mass of 20 kg. Calculate its density.• density = mass / volume
• density = 20/ 0.025
• density = 800 kg/m(3) - 5What is the density of water?1000 kg/m(3)
- 6What happens to objects that have a lower density than water?They float in water.
- 7How do you find the density of a REGULAR solid?1. find out the mass using a pair of scales
2. find the volume of the object using a ruler
3. use the equivalent to find out its density - 8How do you find out the density of an IRREGULAR solid, you?1. find out the mass, using a pair of scales
2. fill up a eureka can to the tip of its spout and then place the object in it
3. the volume of the object is equal to the volume of the water forced out the spout - 9How do you find the density of a LIQUID?1. calculate the mass of the liquid by subtracting the mass of the empty beaker form the total mass of the beaker and the liquid
2. use a measuring cylinder to find out the volume of the liquid
