calculating the mass and dividing it by the volume to get the density‚ then compare densities. 44. A student has several different-size samples of substances I and II. She measures the masses and volumes of these samples and plots the graphs shown in Figure D page 67. Which substance has greater density? How do you know? 2 2 more dense because it doesn’t rise as fast as number one. 45. How can you determine the density of ice? Can you determine the volume of the ice by melting it

C hapter 1 MATTER IN IN OUR SURROUNDINGS As we look at our surroundings‚ we see a large variety of things with different shapes‚ sizes and textures. Everything in this universe is made up of material which scientists have named “matter”. The air we breathe‚ the food we eat‚ stones‚ clouds‚ stars‚ plants and animals‚ even a small drop of water or a particle of sand– each thing is matter. We can also see as we look around that all the things mentioned above occupy space‚ that is

sunken‚ and in gases as well as liquids (i.e. a fluid)‚ Archimedes’ principle may be stated thus in terms of forces: Any object‚ wholly or partially immersed in a fluid‚ is buoyed up by a force equal to the weight of the fluid displaced by the object. — Archimedes of Syracuse with the clarifications that for a sunken object the volume of displaced fluid is the volume of the object‚ and for a floating object on a liquid‚ the weight of the displaced liquid is the weight of the object.

all four general properties. They are mass‚ weight‚ volume‚ and density. The most important property of matter is mass. Mass is how much stuff‚ or matter‚ there is in any given object. Mass is the reason an object has‚ the second property‚ weight. When gravity pulls on an object it forms the weight. Weight is the pull of gravity. Everything takes up space. Volume‚ however‚ is how much space is being taken up by any given object. Density‚ the final property‚ is mass divided by volume. This brings me

It is also important to learn how to combine units to determine concentration and density in order to measure the density and concentration in different dilutions. Procedure Exercise 1 Length Measurements 1) Gather DVD or CD‚ key‚ spoon and fork. 2) Measure the length of each item in centimeters with one degree of uncertainty‚ record. 3) Measure

mass at sea level is 1 kg-force. 1-6C There is no acceleration‚ thus the net force is zero in both cases. 1-7 A plastic tank is filled with water. The weight of the combined system is to be determined. Assumptions The density of water is constant throughout. Properties The density of water is given to be ρ = 1000 kg/m3. Analysis The mass of the water in the tank and the total mass are V =0.2 m 3 mtank = 3 kg mw =ρV =(1000 kg/m )(0.2 m ) = 200 kg 3 3 mtotal = mw + mtank = 200 + 3 = 203
