A urce file Problem 3: A watched pot never boils You need to know exactly how long it will take for your water to boil. Your pot is cylindrical with a radius of 10cm. Your stove delivers 250 Cal/sec of heat energy. Write a java program which will ask the user how deep and warm the water is and then calculates and displays the time in minutes that it will take the water to reach 100 degrees. (Recall that it takes 1 caloric to heat up 1 ml of water by 1 degrec.) Declare and use constants for the rate of heat added and the radius of your pot. Declare and use styleGuide compliant variables for the depth of the water, how warm it starts out, the volume of the water, and the time until the water boils.
