3670 K to Fahrenheit a) In analyzing a sample of polluted sea water, a student measured out 25.00ml water sample using a Pipet. At another point, the same student measured 25ml of the water sample using a graduated cylinder. What is the difference between reporting a value as 25ml and 25.00ml? Given that pipet had an uncertainty of ±0.01 and cylinder had ± 1, rewrite the above two values to account for the uncertainty in each case and predict which one is more precise
(b)What difference exits between the measured values 4.0 g and 4.00g?
A material will float on the surface of a liquid if the material has a density less than that of the liquid. Given that the density of water is approximately 1.0g/ml, will a block of material having a volume of 1.2×104 in3 and weighing 350 lb float or sink when placed in a reservoir of water?
