Purpose: The purpose was to shoot for the assiduity of water, a unbendable cube and stains.
Apparatus: Graduated cylinders (100ml & 15 ml), scale, solid cube, plastic loving cup, ruler, calculator, and stain.
Procedures: A: Density of water
1.Weigh 15ml gradatory cylinder, and calculate scale to zero.
2.Fill with 5ml of water, and weigh again.
3.Write some(prenominal) measurements on a table and calculate density for water.
B: Density of a solid cube.
1.Obtain a solid cube and record the letter on the cube.
2.Measure separately the height, with and length of the cube, with a ruler in centimeters, and calculate the muckle of the cube (centimeters squared).
3.Weigh cube
4.Write both down on a table, and calculate density
5.Obtain the accepted value of the solid cube you have.
6.Then using the percent error formula, calculate your percent error.
C: Density of wits
1.Weigh the plastic cup on scale, and set scale to zero
2.Put one marble in a cup, and weigh the marble. Record mass, then(prenominal) render one marble, and a time and weigh the mass, of the amount of marbles 1-5
3.Then fill graduated with 50ml of water, and measure the volume, of one marble, then two then three and so forth until youve do all 5.
4.Write results on a table and take shape a graph.
Observations: sectionalisation A: Water is clear, odorless, takes the shape of the container its in, and takes the glossary it is in.
Mass(G)Volume(ML)
3.9(G)5.0(ML)
Part B: The cube was a fluid color, heavy and made of aluminum.
Mass(G)Volume(ML)
44.115.4
Part C: Some of the marbles had air bubbles in them, clear expect for the strip of color running through the middle of the marble. They were also round and solid.
witsMass(G)Volume(ML)
15.32
210.34
315.46
420.38
525.510
Results: Part A: The density of water is 0.78. D=M/V 0.78=3.9/5.0
Part B: The density of the cube...If you want to get a full essay, order it on our website: Orderessay
