A Styrofoam cooler contains ice at 0° C. The cooler is leftoutside where the temperature is 30.° C. For the ice to melt intowater at 0° C, it needs to take in 34 kJ of heat. If the cooler hasa total wall area of 0.73 m', thickness 5.0 cm, and thermalconductivity 0.027 W/m-K, how long (in minutes) would it takefor the ice to melt?

Given data: The cooler contains ice at 0°C, i.e. 273K The outside temperature is 30°C, i.e. 30+273K,…

Answered: A Styrofoam cooler contains ice at 0°…

A body falls in a medium offering resistance proportional to the speed at any time "t". If the limiting speed is 15 m/sec and the body attains half that speed in 1 sec, what was its speed after 3 seconds? 0.56 m/s 4.08 m/s 12.97 m/s 9.72 m/s
A tank initially holding 80 gals of fuid with 40 lbs of salt has two sources of fluid being pumped in. One source is pumping pure water in at 8 gal/min and the second source is pumping in a salt solution of 0.5 Ibs/gal at 2 gal/min. The tank is emptying at 10 gal/min. Find the amount of salt in the tank after 30 minutes?
Suppose that a motorboat is moving at 42 ft/s when its motor suddenly quits, and that 11 s later the boat has slowed to 23 ft/s. Assume that the resistance it encounters while coasting is proportional to its velocity, so that dv/dt = - kv. How far will the boat coast in all?
A water tank that initially contains 140 L of solution in which 20 g of salt was dissolved. A solution with a salt concentration of 4 g/L is added at a rate of 6 L/min. The solution is mixed well and was drained from the tank at a rate of 4 L/min. Find the answer for the following question. 1) Find the concentration of the solution in the tank after 30 minutes.
A chamber 27 m beneath the Earth contains hot water with a density of 1000 kg/m³ at a pressure of 955,526 Pa. A narrowing channel leads upwards to a circular vent at the surface having negligible area compared to that of the chamber. At what speed is hot water ejected from the vent? Atmospheric pressure is 1.01 x 105 Pa V = - m/s
