Answer:
The statement is true.
Explanation:
&he pressure exerted by a liquid depends on the height of the liquid column. Where h is height and ρ is density. As the height increases, pressure will also increase.

Answer:
the color we observe is the wavelength that the object reflects back to us.
Explanation:
light is composed of several wavelengths each wavelengths is a particular color . but for higher wavelengths light becomes invisible. the color we observe is the wavelength of light that the object reflects back to us.
The answer is :
2H₂O (l) ------>2H₂ (g) + O₂ (g)
That is ,
Oxidation number of oxygen increases in reaction :
2H₂O (l) ------>2H₂ (g) + O₂ (g)
In H₂O, oxidation number of oxygen is -2 but in O₂ molecule it is 0.
So, oxidation number of oxygen increases in this reaction that is from -2 to 0.
So in the reaction that is 2H₂O (l) ------>2H₂ (g) + O₂ (g) , oxidation number of oxygen increases .
