Science question?

Question

the question is At what temperature does water boil at 1 atm? After this liquid is boiled for 20 minutes what is the temperature of this water? Why?

I dont know what 1 atm means either but it was just in the question so please help to answer this question! Thank you

Answer 1

Water will boil at 1atmosphere (atm) at 100 *C . The heat in the water is known as senable heat. After 20 minutes the water will still be at 100*C but the steam will be much hotter. The steam will be carrying the extra heat known as latent heat. The latent heat is the left over energy not being used to boil the water.

Answer 2

1 ATM means one atmosphere which is another way to say sea level . The temperature is 212 F or 100 C. You can boil it for hours and the temperature will be the same unless you pressurize the vessel.

The water at one atmosphere can't exceed 212/100 degrees, or it will escape as vapor, so if you still have liquid water it will not get any hotter than boiling point unless you increase the pressure.

Answer 3

Water boils at 100 degrees celsius or 212 degrees fahrenheit. After 20 minutes, it's still the same temperature. Further boiling does not increase the temperature of the water, so it really doesn't matter how many minutes have passed.

Answer 4

! atm is the atmospheric pressure at sea level.
As the water starts boiling each CC. of water that is evaporated it will absorber 60 calories. The temp. is 212 deg F. and it will get no hotter.

Answer 5

100C or 212F

Liquid water at the boiling point does not change temperature. Only until it is converted to steam can it increase temperature further.

Answer 6

one atomsphere level=atm
212 degree F 0r 100 C

212+, because there is less water to heat up so it will get hotter but keep in mind that steam is 212 or more too
