An lce cube at a temperature of -20 oC is put in a plastic bowl and which is then placed in a microwave oven, and the oven is turned on. When the oven is turned off, the bowl contains water that is at a temperature of 60 °C. Assuming the microwave transferred energy to the ice at a constant rate throughout, draw a graph (below) of the temperature of the H20 as a function of time. The endpoints of the...
PHYS 205 Winter 2019 Lab 1 Homework NAME 4. Suppose we heat sample A, which is 150 g of ice at-10 C, and sample B, which is 150 gofice at 0 °C, in the same microwave oven until both samples of water are at 30 °C. Will the time taken to heat sample A be (a) longer than, (b) shorter than, or (c) equal to the time to heat sample B? Explain your reasoning. 5. An ice cube at a...
Some ice cubes at 0°C with a total mass of 441 g are placed in a microwave oven and subjected to 750. W (750. J/s) of energy for 5.00 minutes. (Assume all the energy of the microwave is absorbed by the water and no heat loss by the water.) (Enter your answer to three significant figures.) What is the final temperature of the water? C
