A student designed an experiment to show how water is recycled through the atmosphere. Which of these is least likely to be a part of the experiment? A) A burner to heat water. B) A beaker in which water is boiled. C) A cup of ice cubes to cool the water. D) A cold glass plate on which water vapor condenses. I think it's D but i'm just checking if i'm correct

OpenStudy (mazmaz):

C i think because I cubes are H2O and would mess with the actual scientific proces. The water can cool by itself and condense on the cool plate source: Years of science and father who runs a research lab BUT... All of them seem to be possible but I say I would preffer to di it without the Ice. it says least likely

OpenStudy (gabebae):

So it's D?

OpenStudy (mazmaz):

I think it is C try to tag somone for a 2nd opinion

Sorry! OS crashed.

OpenStudy (scarlettfarra2000):

Recycled water is highly treated sewage effluent that is produced at a sewage treatment plant that meets California Code of Regulations, Title 22 criteria. It is treated to a level that does not meet drinking water standards so I also think its C

OpenStudy (gabebae):

@ScarlettFarra2000 You copied and pasted that answer from a different site!

OpenStudy (cheesecakekitten):

C. because heat is what makes water evaporate, so adding cold ice cubes would di the opposite

OpenStudy (gabebae):

I have more Which of these instruments can be used to predict a thunderstorm? A) wind vane ( I know that measures the wind ) B) rain gauge ( measures the amount of rain fallen) C) radiosonde D) thermometer

OpenStudy (cheesecakekitten):

Radiosonde? Let me check...

OpenStudy (cheesecakekitten):

Yes, because scientists use radio-magnetic pulses to locatedetect possible earthquakes and other moments in the earth. Also because all the other tools serve different purposes. a wind vane measures wind speed, a rain gauge measures the amount of rainfall, and a thermometer measures temperature.

OpenStudy (cheesecakekitten):

C.

OpenStudy (gabebae):

A tornado uproots trees and plants. Which Earth systems interact during this process? A) soil and hydrosphere B) hydrosphere and biosphere C) atmosphere and biosphere D) hydrosphere and atmosphere

OpenStudy (cheesecakekitten):

B. The hydrosphere (Weather and natural phenomenon) and the biosphere (Plants, animals, and ecosystems) are interacting.
