A physicist makes a cup of instant coffee and notices that, as the coffee cools, its level drops 3.00 mm in the glass cup. Show that this decrease cannot be due to thermal contraction by calculating the decrease in level if the 350 cm3of coffee is in a 7.00-cm-diameter cup and decreases in temperature from 95.0ºC to 45.0ºC. (Most of the drop in level is actually due to escaping bubbles of air.)
