Kitty [74]

No

Explanation:

Tap water will not boil and freeze at those exact temperature which are the boiling and freezing points.

O°C and 100°C are the boiling points of pure water.

Pure water is a pure substance with a definite composition made up of 2 atoms of hydrogen and 1 atom of oxygen.

Pure water boils at  100°C  and freezes at O°C ,

  • Tap water is not pure water.
  • It has some impurities in it which causes causes the elevation of the boiling point of liquids and widening of the boiling range.
  • Tap water is treated water that contains some other dissolved chemicals.

PLEASE HELP ASAP!!! CORRECT ANSWER ONLY PLEASE!!!<br><br> Which number shows the wavelength?
Ray Of Light [21]

If you read the question carefully, you can find the answer right there in it.

In fact, you don't even have to read the whole question ... you only need to read one word.

In fact, you don't even have to read the whole word ... you only need to read part of the word.

The word to read is "wavelength".

The important part of the word is "length".

<em>Now</em> it's time to look at the picture:

#1 is a height.

#2 is a place on the wave

#4 is a place on the wave

<em>#3 </em>is the only thing in the picture that's a "length" of anything.
