As a race car races around the track, friction between the tire and the road heats the air in the tires and the pressure inside the tires increases. what is the best explanation for this?

particles in the air hit the inside of the tire walls less frequently.
air particles speed up and collide with the tire walls more often.
air particles get larger and make the gas take up more space.
the heat causes the rubber in the tires to create new air particles.

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.

so what is the problem with your lab report and whats the subject of the lab report? i will you
