Answer #1

Solution:

The correct answer is option 3. The water will evaporate faster but the temperature will not increase. Before water starts boiling the heat applied to the water will use to increase the temperature of the water. But once it starts to boil, the extra heat is used to change the water to steam keeping it at the same temperature(i.e boiling point). The heat required to change water to steam is it's latent heat of vaporisation. In the given question, water has reached its boiling point. Therefore third option is the correct answer.

150 grams of boiling water (temperature 100°C, heat capacity 4.2 J/gram/K) are poured into an aluminum pan whose mass is 970 grams and initial temperature 25°C (the heat capacity of aluminum is 0.9 J/gram/K). (a) After a short time, what is the temperature of the water? (b) What simplifying assumptions did you have to make? The thermal energy of the aluminum doesn't change. Energy transfer between the system (water plus pan) and the surroundings was negligible during this time. The...

French press coffee maker, I usually heat up water in a pot on the stove. Let’s say that it usually takes 7 minutes for 2 cups of water that starts at 20 degrees Celsius to reach 95 degrees Celsius. Something that has happened before is I have walked away from the stove and then forgot about it for some amount of time. If I come back 25 minutes later (from when I turned the stove on), will there be any...

During a strenous workout, an athlete generates 2140.0 kj of heat energy. What mass of water would have to evaporate from the athletes skin to dissipate this much heat? Note: at 100 C, the boiling point of water, the molar heat of vaporization of water is 40.67 kj/mol. at 25C, approximately room temperature the molar heat ofvaporization of water is 44.0kj/mol

Heat capacity is the amount of energy it takes to warm up an object by 1K. The heat capacity of water is 4.18J/g/K; in other words, if you add 4.18 J to 1 g of water, the water will warm by 1 K. Imagine you have a cup containing 200 g of water that is absorbing 150 W of power. At what rate is the water warming? Answer is degrees K per second. If the cup starts at room temperature,...

You are making pesto for your pasta and have a cylindrical measuring cup 10.1 cm high made of ordinary glass (B(beta)=2.7x10-5(C)-1) and that is filled with olive oil (B(beta)=6.8x10-4(C)-1)to a height of 1.10 mm below the top of the cup. Initially, the cup and oil are at a kitchen temperature of 21.4 C. You get a phone call and forget about the olive oil, which you inadvertently leave on the hot stove. The cup and oil heat up slowly and...

An urban legend suggests that some people add salt to water used for boiling potatoes or noodles in order to raise the temperature and help them cook faster. One tablespoon of salt is about 20 g (or one-third of a mole). Assume that the cooking pot contains 1000 g (or 1 liter) of water. What would be the new boiling point of the salted water in degrees Celsius?
