  • Water is boiled in a cup and put to cool down inside a room. The air temperature in the room is increasing linearly according to the function Ta(t) = 22 + 0.015t (t in minutes, T in Celsius). Assume Newton’s Law of Cooling is satisfied: the rate of change of water temperature is proportional to the difference between the temperature of the water and the temperature of the environment. The temperature of the water was checked after 8 minutes and it was 82 Celsius. Explain and graph Ta. Establish and solve an Initial Value Problem to express the water temperature as a time function, graph this function.

Take a hard boiled egg or tippee top and put it lying down on a table and start to spin it, if you spin it fast enough it will start to spin in an upright position. How do the egg, and tippee top remain stable in their rotating positions? What other toys can you think of are based on interesting quirks of physics? (Try to explain the physics behind them!)

A- a small volume of cold water is used to cool off a cup of coffee that is initially too hot to drink. How many mL of water at 4.0oC must be mixed with 485 mL of hot coffee (95.0oC) so that the resulting combination has a temperature of 70.0oC? Assume that the coffee and water have the same density and specific heat.    B- A 5.00 cm3 sample of aluminum at room temperature (25.00oC) was dropped into a 1 L...

A cup of coffee is made with boiling water at 100 and stands in a room where the temperature is 25. The change in temperature, H in degrees , with respect to time t, in minutes, is given by the following differential equation. (dH)/(dt)=-k(H-25) Solve this differential equation. If the coffee cools to 90 in 3 minutes, how long will it take to cool to 60 degrees? Round your answer to the nearest integer.
