Wine is often bottled in 0.750 L containers.  Using the appropriate equivalence statement from Table 2.7 in your book, calculate the volume of such a wine bottle in quarts. Racing cars at the Indianapolis Motor Speedway now routinely travel around the track at an average speed of 225 mi/h.  What is this speed in kilometers per hour? Los Angeles and Honolulu are 2588 mi apart.  What is this distance in kilometers? The United states has high-speed trains running between Boston and New York capable of speeds up to 160 mi/h.  Are these trains faster or slower than the fastest trains in the United Kingdom, which reach speeds of 225 km/h?

Matter and Measurement

In the universe, there is matter, energy, and void space. The universe contains energy and void space. The definition of matter can be considered as something which possesses mass and consumes space. Chemistry is that branch of science which deals with the study of matter. Under chemistry, nature, composition, and the changes occurring to matter are discussed.
