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 potentially useful information: cal c(water) 1.0 Ltusion (water)- 80 cal & k cal c(ice) 0.49 Lvap (water)- 540 cal gK 1. Last week we took a look at this problem and only required a qualitatively correct response. Most of you did a good job of breaking the overall process into three distinct portions. This week we built on some of those ideas and are in a better position to be more quantitative. As you revisit this problem, pay attention...

A) What is the final temperature of the system? Ignore any heat
exchange with the bowl or the surroundings.
B)What is the amount of ice (if any) remaining?
A large punch bowl holds 3.80 kg of lemonade (which is essentially water) at 25.0 °C. A 5.10x10-2. kg ice cube at -11.0 °C is placed in the lemonade.

Problems 1 through 5 below refer to the following graph. A 200 gram ice sample is placed in a closed (and otherwise evacuated) beaker on top of a bunsen burner. The initial temperature of the ice is -20 degrees Celcius. It is heated until all of the ice melts and turns into water, the water is heated until it boils, and it continues to be heated until all of the water turns into steam. The temperature of the water (in...

(a) How much heat transfer (in kJ) is necessary to raise the temperature of a 0.210 kg piece of ice from -22.0°C to 132°C, including the energy needed for phase changes? (Assume the substance remains at a constant volume throughout each stage of the heating process.) (b) How much time (in s) is required for each stage, assuming a constant 19.0 kJ/s rate of heat transfer? (Enter your answers as a comma-separated list. Enter your times in order from the...
