A test tube contains 2.61x10-4 m3 of liquid carbon tetrachloride (β = 1240x10-6 (C°)-1) at a temperature of 64.0°C. The test tube and the carbon tetrachloride are cooled to a temperature of -13.0°C, which is above the freezing point of carbon tetrachloride. Find the volume of carbon tetrachloride in the test tube at -13.0°C. number units
