- You have a summer job with a company that designs cookware. Your group is assigned the task of designing a better pasta pot. You are very excited by a new strong, light alloy the group has just produced, but will it make a good pasta pot? If it takes more than 10 minutes to boil water in a pasta pot, it probably won't sell. So your boss asks you to calculate how long it would take water at room temperature (23°C) to reach boiling temperature (100°C) in a pot made of the new alloy. Your colleagues tell you that a typical pasta pot holds about 2 liters (2.0 kg) of water. They estimate that a pot made of the alloy would have a mass of 550 grams, and a specific heat of 860 J/(kg °C). You look in your physics book and find that water has a specific heat of 4186 J/(kg °C) and its heat of vaporization is 2.26 x 106 J/kg. The owner's manual states that the burners on your stove deliver 1500 Joules of heat per second. You estimate that about 15% of this heat is radiated away.arrow_forward17) Calculate the osmotic pressure of 25% of the urea solution at a temperature of (37 °C), knowing that the molecular weight of urea is (R = 0.0821 L atm.
