6. You, have decided to freeze water in your freezer. There are 16 small containers in a 10 cm x 20 cm tray with a depth of 3 cm. lf the freezer temperature is=10 deg Celsius and the water temperature initially was 20 degrees celsius, find the time it will take to freeze the water completely. Assume the heat escapes only through the top of the water surface.

You fill an ice tray with water at 25 degree celsius and place it into the freezer. Each cube has a volume of 30 mililiters (a mass of 30 g). Assume that heat is transferred from the water in each cube in the ice cube tray to the surrounding cold air in the freezer at a constant rate of 40 J/min. You can consider that the water (whether liquid or solid) in each cube is at uniform temperature. You can...

Question: After a long day of food, football and family, you decided to relax with a nice glass of wine. Of course, you have to have it just perfect in order to fully enjoy it, so you want your beverage to have a final temperature of 10 degree Celcius. You fill your favorite glass cup (mass of 279g and C of glass = 840 J/kgC) initially at 22 degree Celcius with 480g of your favorite wine innitially at 15 degree...

6. Where you are now, you want to have tea while solving questions. The water, which is found in a thin steel teapot with a diameter of 12 cm, is boiling. The heat transport coefficient between the teapot base and the boiling water is 10 kW/m2K. Since the heat flow ingrair is 40 kW/m2; a) Find the surface temperature of the teapot base. b) Find the heat given to the water for 30 minutes and the amount of water evaporated.

. Suppose a vertical pipe is to be used as part of a system to manually cycle nutrients upward from the floor of a lake. (Many lakes do this naturally, some do not. Green Lake, near Syracuse, NY, is one such lake.) A pump is to be installed on the lake floor at the base of the pipe. The base of the pipe will have a diameter of 9 cm. The nozzle of the pipe at the top will have...

You will also analyze an “unknown” sample that contains a mixture of two dyes. Dye molecules with lower molecular weight or greater electrical charge will migrate faster through the gel, than dye molecules with greater molecular weights or lesser electrical charge.
