Which of the following lines(of latitude or longitude) would represent by 180 longitude?

south pole
equator
prime meridian
north pole
international date line

International date line  would represent by 180 longitude

Explanation:

An "imaginary line of demarcation" on the earth’s surface that runs from the south pole to the north pole. It demarcates the one-day calendar change to the next. Through the centre of the pacific ocean, it passes with 180-degree longitude and halfway through the world from the Greenwich meridian.

Though in many cases the imaginary line of demarcation follows 180-degree meridian exactly. And at other places, the imaginary line of demarcation deviates east or west through the apex.

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.
