I am very hungry, so I need to cook myself some ramen on the stove. I fill up a pot with 2 kg of water and place the pot on my stove which has an average power output of 8.22 kW, raising the water's temperature from 31.5°C to its boiling point (roughly around 100.6°C). How long after placing the pot of water on the stove does it take for the pot of water start boiling in seconds?
Hint: Water has a specific heat of 4.2 k J k g ∘ C, and this is an energy transformation problem. Start with finding Q.
A 300 g aluminum pot containing 0.50 L of water is placed on the 1 kg iron hot plate on an electric stove. The heating element of the hot plate is rated at 1.5 kW. If the hot plate, the pot, and the water are all at 20°C when the heating element is switched on, how long will it take until the water begins to boil? Neglect heat losses to the surroundings.
A 0.264-kg coffee mug is made from a material that has a specific heat capacity of 907 J/kg C° and contains 0.340 kg of water. The cup and water are at 31.2 °C. To make a cup of coffee, a small electric heater is immersed in the water and brings it to a boil in two minutes.
Assume that the cup and water always have the same temperature and determine the minimum power rating of this heater.

- You are a veterinarian’s assistant for the summer and are helping with a minor surgery on a cow. She has asked you to sterilize a scalpel and a hemostat by boiling them for 30 minutes. You boil them as ordered and then quickly transfer the instruments to a well-insulated tray containing 200 grams of sterilized water at room temperature (23◦C) which is just enough to cover the instruments. After a few minutes the instruments and water will come to the same temperature, but will they be safe to hand to your friend without being burned?
