Answer: For boiling 1 cup of water, it takes about 1 minute in a microwave, 2 minutes in an electric kettle, and 3 minutes in a pot on the stove.
How long does it take to boil 1 cup of water 2 cups of water?
On a stove it would take about 5 minutes to boil 2 cups of water, depending on the stove and the factors I mentioned before. Usually it’s 2 minutes per cup of water. It would take a lot longer to boil water on a grill. In a microwave, it would take about 1.5 to 2 minutes to boil 2 cups of water.
Which took longer to boil 1 cup of water or 2 cups of water?
Usually heating 2 cups will take slightly less than twice one cup, because of the cube-square law, the water won’t have twice the surface area. The faster you heat though, the less the difference will be. Also, if you literally heat two cups of water, like in a microwave, then it will take almost exactly twice as long.
How long does it take to cool 2 cups of water?
answer: Cooling from 100 to 45 in a closed container, not sealed so you don’t get a vacuum, probably takes 100 minutes or so. 50–45 20 min, but you said open pot, so it’s faster, as you get material loss (evaporation/”sensible heat”) as the water cools.
How do you boil water in a cup?
- Turn the burner on medium heat.
- Fill a paper cup nearly to the brim with water.
- Using tongs, hold the cup of water about six inches above the heating element.
- Continue holding the cup over the heat. The paper or burn, or the water will boil. Record your observations. How can you explain what you saw happen?
How long does it takes to boil 1 cup of water?
For boiling 1 cup of water, it takes about 1 minute in a microwave, 2 minutes in an electric kettle, and 3 minutes in a pot on the stove. The time it takes to boil water depends mostly on the following factors: Amount of water. The container.
What happens to the water when it boils?
When water is boiled, the heat energy is transferred to the molecules of water, which begin to move more quickly. Eventually, the molecules have too much energy to stay connected as a liquid. When this occurs, they form gaseous molecules of water vapor, which float to the surface as bubbles and travel into the air.
How long does it take to cool 1 cup of water?
Answer. Answer: Cooling from 100 to 45 in a closed container,not sealed so you don’t get a vacuum,probably takes 100 minutes or so.
What happens to the water as it boils Brainly?
Answer: The temperature of the water increases. The water also releases bubbles and bacterias are being killed at this state. The water is also gradually decreasing as it evaporates in our atmosphere.
What conclusions can you draw from your results How is temperature related to heat?
Answer. Answer: heat is the total energy of the motion of the molecules inside the object or particle, whereas Temperature is merely a measure of this energy. The relationship could be, the more heated an object is there higher the temperature the object will have.
How long does it take to boil 8 cups of water?
It takes five to 10 minutes to boil 6 to 8 cups of water.
How long does boiled water stay sterile?
Boiled water can be kept in sterilized, properly sealed containers in the refrigerator for 3 days or for 24 hours if kept at room temperature out of direct sunlight.
What happened when water is cooled?
When water is cooled, the water molecules move slower and get closer together. This makes cold water more dense than room temperature water. Since cold water is more dense, it sinks in the room temperature water. When water is heated, the water molecules move faster and spread out more.
How long does it take to boil 1 cup of water in the microwave?
Based on the wattage of your microwave, set the time for boiling in accordance with this and the amount of water you plan to boil. Going off of this time will be the safest way to ensure boiling without injury. Microwaving water should take 1-3 minutes for one cup of water, depending on the wattage and elevation level.
Is it bad to microwave water for tea?
Slate says that the microwave will result in unevenly hot water: … Overheating your water can make your tea taste bitter and weird, says Slate. But those without a kettle shouldn’t despair just yet: as long as you’re willing to drink only green tea, the microwave is the way to go.
How can water boil in paper cup without burning it?
Water can be boiled in a paper cup because, the heat energy supplied to paper cup rapidly passes on to water. Thus, ignition temperature of paper is not achieved and, hence, it does not catch fire.
