Why does 2 L of boiling water not have twice as great a temperature as 1 L of boiling water?

Why does 2 L of boiling water not have twice as great a temperature as 1 L of boiling water?

Two liters of boiling water have twice as much kinetic energy as one liter. The temperatures are the same because the average kinetic energy of molecules in each is the same. There is more molecular kinetic energy in the bucketful of warm water than in the small cupful of higher-temperature water.

How long does it take for 2 liters of water to boil?

To boil the pot of water, you need from 6 to 12 minutes. If you have one liter of water in your pot. If you have 2 liters, the time will be increased by one and a half times. In a microwave, it will take 4 minutes for one liter of water.

How long does it take to boil 1 Litre of water in a kettle?

In general they use an electric kettle. A 1 KW kettle filled with 1 liter of water from the cold supply at 12 deg C takes 1000 gm/liter x 1 calorie per gm times (100 – 12) degrees C x 4.2 joules/calorie times 1 KW /1000 watts times 1 minute / 60 seconds or about 6.2 minutes.

Does it take longer to boil more water?

The time is proportional to the mass of water, so if you double the mass of water you double the time needed to boil it. The amount of energy needed to boil a certain amount of water from a certain initial temperature, scales linearly with the amount of water.

Why can you touch the aluminum pan of the frozen dinner soon after it has been taken from the hot oven but you will burn your fingers if you touch the food it contains?

You can touch the aluminum pan of a TV dinner soon after is has been taken from the oven, but you will burn your hand if you touch the food it contains. Explain. The aluminum has a lower specific heat than the food (specifically the water in the food) and it therefore heats up and cools off more quickly.

When an iron ring is heated the hole becomes?

OK, the ring gets thicker, but also larger. Think of looking at the ring through a slightly magnifying glass (say with a magnification of 1.01x, which will add 1% to all dimensions. Then everything will be enlarged: the outside diameter, the thickness, but also the diameter of the hole.

How much gas does it take to boil 1 Litre of water?

To heat 1 liter of water by 1C requires 4.18kJ so you then multiply this by 70 (the temperature difference) and then by 150 (the total amount of water) which gives 43,890kJ. So at 100% efficiency you will need 0.9kg of gas.

Why does less water boil faster?

It takes less energy to bring water to the boiling point when atmospheric pressure is lower. Water will boil at a lower temperature at a higher altitude because of less energy.

Why does tin foil not get hot in the oven?

The thermal mass of an object is its ability to store or absorb heat. Things that are considered ‘difficult’ to heat generally have a high thermal mass. Aluminum foil has a low thermal mass on account of having such low mass and such a high surface area. That’s why aluminum foil is not able to ‘hold’ much heat.

Does tinfoil get hot?

Actually, aluminum foil does get hot when it is in the oven. For example, if you wrap up a baked potato in foil and cook it in the oven, the foil will be too hot too touch. When you touch the foil, this thermal energy is quickly dissipated into your hand, which has much more mass.

Which is the same for boiling water and temperature?

There is twice as much molecular kinetic energy in 2 liters of boiling water as in 1 liter of boiling water. Which will be the same for both? A. Temperature Explanation: Average kinetic energy of molecules is the same, which means temperature is the same for both.

How long does it take to boil one liter of water?

What gives the heat to boil water is also essential. If we decide to boil one liter of liquid using a stove, the whole procedure will take about ten to fifteen minutes. On the contrary, using a water heater, we can reach the same result in only five minutes boiling the same amount of the liquid.

How much solute is in a liter of solution?

(1) water, only (2) water and sand, only (3) water and salt, only (4) water, sand, and salt crude oil by means of distillation? (1) melting point (3) solubility (2) conductivity (4) boiling point of solute per liter of solution. When the student’s solution was analyzed, it was found to contain 8.90 grams of solute per liter of solution.

Which is faster 250 ml or 1 liter of water?

250 ml of water will boil at 100 F temperature, it will boil faster than an 1 liter of water.
