Volume Lab: Measurement And Water Displacement

Volume Lab

In this four parted lab the purpose is to use measurement and water displacement and calculations to find the volume of various objects.

Part A questions were how much drops of water were needed to make 1mL the original hypothesis made was ten drops however this was proven wrong once the data in which twenty drops of water rose 10 mL of water to 11 mL of water, nineteen to rise from 11 mL to 12 ml, and finally eleven drops of water to rise from twelve mL to thirteen mL. Once the average was calculated which was 16.6 drops, which meant on average that's how much it needed to make one mL. By subtracting from the average with the hypothesis the hypothesis was revealed to be 6.6 drops off.

Part B questions were based on water displacement. In which the question was how much was the difference between 20 mL of water and 3 marbles. To figure out the answer knowing how much water was in the cylinder is before adding the 3 marbles so once the marbles were added you can subtract the original volume from the new volume. In this case we know that the cylinder held 20 mL of water so upon adding all three which rose it to 28 ml all we had to do was 28 mL - 20 mL which equals 8ml in difference which can also be translated as to what the volume for 3 marbles was.

Because of the question it asks to find the volume of any box. The chosen box in the lab measurements was then inputted into the formula 31 cm x 21 cm x 12 cm which resulted in the volume being 7812
