Questions like 0 X infinity and 1 to the power of infinity. But why are these math questions undefined? Like anything multiplied by 0 is always 0, and 1 to the power of anything is always 1.

I know the earth is closest to the sun during the northern hemisphere's winter solstice. It is the northern hemisphere's "tilt" away from the sun that helps "produce" our winter. So, due to the earth's proximity to the sun and its "tilt," during our winter, does the southern hemisphere have more warmer summers. They are closest to the sun and tilted towards the sun.
Are winters in the southern hemisphere colder? They are then further away and tilted away.

A gas system has pressure, volume and moles of 1410 torr, 8.47 L and 0.346 moles, respectively. What is the temperature in Celsius?
279C
84C
127C
228C
110C

What is the relationship between the volume of a gas and the number of moles? What is the name of the law from which we derive this relationship?

The temperature at sea level is 86oF. If we ascend to an altitude of 2,500 feet, what is the temperature at that height?

100F
53F
98F
77F
64F
55F

Convert 750 kPa to atm.

70 atm
75.4 atm
7.403 atm (I got this one is this correct)?
6.983 atm

A sample of gas initially occupies 6.0 cubic meters at a pressure of 1.5 atm. The pressure is then expanded to 2.0 atm. The temperature remaining constant, what is the new volume of the gas?
(I got 18 is that correct)?

Can the Northern Lights be seen from anywhere in the UK? Also can they be predicted to the point that I could go to where-ever on a certain evening or night and see them?
