Consider two liquids: liquid A, with a density of 0.98 g/mL, and liquid B, with a density of 1.03 g/mL. Notice that one density is known to have two significant figures and the other to have three. Calculate the volume of liquid A in a sample that weighs 9.9132 g; be sure to express your result to
A scientific oven is programmed to change temperature from 80.0 °F to 215.0 °F in 1 minute. Express the rate of change in degrees Celsius per second, and use the convention of significant digits to express the uncertainty in the rate.
Th e average body temperature of a cow is about 101.5 °F. Express this in degrees Celsius and in kelvins, using the correct number of significant figures.
“No two substances can have the same complete set of physical and chemical properties.” Present arguments for and against this statement.
The main weapon on a military tank is a cannon that fires a blunt projectile specially designed to cause a shock wave when it hits another tank. The projectile fits into a finned casing that improves its accuracy. Calculate the mass of the projectile, assuming it is a cylinder of uranium that is
