(1) The specific gravity of a urine sample is found to be 1.110 at a temperature of 24C. The specific gravity of this urine was determined with a urinometer. What is the corrected specific gravity value of this sample? (2) We've learned that urinometers are usually calibrated at 15 C and that we have to correct for samples that are above or below this temperature. This is because the density of a liquid changes with temperature. Using the density formula, explain why temperature affects the density of a liquid. Explain what happens to the density of a liquid as the temperature is raised and lowered.
