Physics

When boiling water, a hot plate takes an average of 8 minutes [min] and 55 seconds [s] to boil 100 milliliters [mL] of water. Assume the temperature in the lab is 75 degrees Fahrenheit [°F]. The hot plate is rated to provide 283 watts [W]. If we wish to boil 100 milliliters [mL] of acetone using this same hot plate, how long do we expect the process to take? Acetone has a boiling point of 56 degrees Celsius [°C]. The specific heat capacity of water is 4.18 joules per gram degree Celsius [J/(g °C)]. Acetone has a specific gravity of 0.785 and a specific heat capacity of 2.15 joules per gram degree Celsius [J/(g °C)]. [Hint: You must determine the efficiency of the hotplate.]
