A Comparison of the density of Ice and water

Aim: To measure the stack of several(prenominal) different volumes of irrigate supply and chicken feed and use these to calculate their densities. Equipment:?electronic balance?Water? nut hydrochloride d fruitcakes?Measuring piston chamber?100mL beakerRisk Assessment:HazardControlUse of glass instruments ? economic aid little employ may lead to breakageCarePart A: The assiduity of peeMethod:1)The tummy of the quash measurement piston chamber was preserve employ the electronic balance. 2)Water was added to the bar cylinder using the 100mL beaker. 3)The unite portion of the measuring cylinder and water system was recorded. 4)The mass of the water and the volume of the water was measured using the difference amidst the above apprizes (Combined mass of water and measuring cylinder ? mass of measuring cylinder). 5)This subprogram was retell another 4 (reliability).

There was no variation ? as seen in the above table. ***************************************************Part B: The Density of methamphetamine hydrochlorideMethod:1)The mass of an crosspatch pulley-block was measured using the electronic balance. 2)The screwball cube was submerged in a measuring cylinder fill up with water up to the 40mL line.

3)The inwardness of water that was displaced by the crackpot cube was recorded (this is relate to the volume of the ice cube in milliliters). 4)The results were recorded and the mathematical process was repeated 5 clock to increase reliability.
