The Sun advances 15 degrees an hour; that is, 15 degrees every 60 minutes. You can base your calculations on that. If you live near the equator, after sunset the Sun will move directly downwards; if you live at higher latitudes, for example in Europe, the Sun moves at an angle, so while it will still move (for example) 15 degrees in an hour, it will not be 15 degrees below the horizon.
Angle of 360 degrees = 1 hour = 60 minutes of time so 6 degrees = 1 minute of time so 72 degrees = 12 minutes of time. I have used "minutes of time" as the unit of time to avoid confusion with minute as a unit in which angles are measured (1/60 degree).
0 degrees. No -- this is a trick question. At 6:00 the hands are at 180 degrees, but by the time the minute hand has moved to 30 minutes the hour hand has moved on to half way between '6' and '7', so the angle between the hands is 360/24 degrees = 15 degrees.

1/6 of half a rotation = 1/12 of a rotation = 1/12 of 360 degrees = 360/12 = 30 degrees.
That depends on the exact moment of the day (between the time you write the question and I answer, the Moon may already have moved ahead quite a bit), and on where exactly you live. In other words, the Moon can be anywhere between 90 degrees above and 90 degrees below the horizon, depending on the above-mentioned circumstances.
The Prime Meridian is by definition 0 degrees longitude. So that part is a given simply because you're at the Prime Meridian. Polaris is directly over the North axial pole. If you were at the equator, Polaris would be right at the horizon (zero degrees above the horizon). If you moved 10 degrees north, Polaris would appear above the horizon by the same amount. So if Polaris is 50 degrees above the horizon, you must be 50 degrees north of the equator (meaning you're at 50 degrees North latitude).
1 hour = 60 minutes therefore: It would have moved (1/60) x 60 minutes = 1 degree

The horizon is the boundary between the World and the sky. You can see it most easilly on a body of water such as a lake or the sea, where ther is an obvious line between water and sky.
the horizon treadmill is easy to move around in one's home. The great thing about this treadmill is that it folds up easy and can be moved around on the wheels on the bottom of it.
The sun lazily dipping below the horizon. The waves whispering secrets to the shore. The colors of the sky dancing in harmony. The seagulls bidding farewell to the day with a final chorus.

The hour hand moves at a constant rate completing a 360 degree circle once every 12 hours. 5 minutes is 1/144 of 12 hours. Therefore the hand will have moved by 360/144 = 2.5 degrees.
Ice cream needs to be kept below freezing, because it has ICE in it, and ice needs to be kept at 0 degrees centigrade or lower. On average a fridge is 4 degrees centigrade so it will melt in the fridge...
