Question 3 2. Another plastic-like piece has a mass of 65.389 grams and displaces 53.652 grams of water(measured at 24.6 °C). Is this piece likely to be composed of the same material as the sample inproblem 1? Explain using the Claim-Evidence-Reasoning process.3. Here are two possible methods for measuring the volume of an irregular shaped object.a) Add it to a graduated cylinder containing a known volume of water. Measure the change inthe volume of the water after the object has been added. The graduated cylinder isgraduated in 1 mL increments.b) Add the object to vessel that is full of water. Collect and measure the mass of the waterthat is displaced on a digital balance that provides mass to the 0.001 g. Determine thevolume by comparing to the density of water table given in table 1.1.Which method would be more likely to produce a more precise measure of the volume of anobject?

2. Another plastic-like piece has a mass of 65.389 grams and displaces 53.652 grams of water
(measured at 24.6 °C). Is this piece likely to be composed of the same material as the sample in
problem 1? Explain using the Claim-Evidence-Reasoning process.
3. Here are two possible methods for measuring the volume of an irregular shaped object.
a) Add it to a graduated cylinder containing a known volume of water. Measure the change in
the volume of the water after the object has been added. The graduated cylinder is
graduated in 1 mL increments.
b) Add the object to vessel that is full of water. Collect and measure the mass of the water
that is displaced on a digital balance that provides mass to the 0.001 g. Determine the
volume by comparing to the density of water table given in table 1.1.
