The substance in *a* gives a colorless solution. What will you see if you add 300 g of it to 100 g of water at 25°C? *a* was randomly given and no figures shown, depending on the question asked

altitude, density, pressure

air gets less dense the higher the altitude and also the air pressure is less as altitude rises.

a

explanation:

pie chart because it is in percents ( % )

the best answer is d because the strong cohesion is caused by the ability of water molecules to undergo hydrogen bonding.

a is incorrect because when water solidifies, it becomes   ice, which expands and occupies a bigger volume for the same mass of water in its liquid state.

b is incorrect because water has high surface tension. besides bonding to itself it hydrogen bonds to other molecules at the top decreasing possibility for breaking of attractive forces.

c is incorrect because the water molecule has oxygen which is highly electronegative and so pulls the electron pair towards itself creating a dipole moment, making the molecule polar.

e is incorrect because water has strong adhesion, ability to stick to other molecules such as glass because of this molecules having stronger hydrogen bonding than water.
