Does the amount of air change the time it will take to burn completely?

Explanation:

The answer is yes. Adding O2 to a fire, feeds a fire creating bigger flames or almost completely burning a building,.. etc

depending on what kind of structure.

little O2 usually makes a fire burn itself out because there is not enuf oxygen or its contained...

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.
