Get started for freeA cylindrical glass bottle \(21.5 \mathrm{~cm}\) in length is tilled with cooking oil of density \(0.953 \mathrm{~g} / \mathrm{mL}\). If the mass of the oil needed to fill the bottle is \(1360 \mathrm{~g}\), calculate the inner diameter of the bottle.
Classify the following as qualitative or quantitative statements, giving your reasons. (a) The sun is approximately 93 million miles from Earth. (b) Leonardo da Vinci was a better painter than Michelangelo. (c) Ice is less dense than water. (d) Butter tastes better than margarine. (e) A stitch in time saves nine.
One gallon of gasoline in an automobile's engine produces on the average \(9.5 \mathrm{~kg}\) of carbon dioxide, which is a greenhouse gas, that is, it promotes the warming of Earth's atmosphere. Calculate the annual production of carbon dioxide in kilograms if there are 250 million cars in the United States and each car covers a distance of \(5000 \mathrm{mi}\) at a consumption rate of 20 miles per gallon.
Carry out the following operations as if they were calculations of experimental results, and express each answer in the correct units with the correct number of significant figures: (a) \(7.310 \mathrm{~km} \div 5.70 \mathrm{~km}\) (b) \(\left(3.26 \times 10^{-3} \mathrm{mg}\right)-\left(7.88 \times 10^{-5} \mathrm{mg}\right)\) (c) \(\left(4.02 \times 10^{6} \mathrm{dm}\right)+\left(7.74 \times 10^{7} \mathrm{dm}\right)\) (d) \((7.8 \mathrm{~m}-0.34 \mathrm{~m}) /(1.15 \mathrm{~s}+0.82 \mathrm{~s})\)
Convert the following temperatures to degrees Celsius: (a) \(77 \mathrm{~K}\), the boiling point of liguid nitrogen, (b) \(4.2 \mathrm{~K},\) the boiling point of liquid helium, (c) \(601 \mathrm{~K},\) the melting point of lead.
