Not sure if this is a real physics question... but yes, pushing against a wall is tiring even though no "work" is being done. Its isometric conditioning. Think of this: Put your hands in front of you and press them together as hard as you can for as long as you can. This will tire you out pretty quick.

Why do you become physically tired when you push against a wall and fail to move it even t?
Surprisingly, there is actually work being done! However, if a single person's just leaning against a wall, pressing their weight actively into it, there's not enough pressure being exerted on the wall to make it move. It does experience the pressure, but the other forces of the rest of the wall pressing in on it, gravity holding it together, all push back more. As well, even if no work was truly being done against the wall, locking your arms in one spot and applying pressure to your own muscles works those muscles to fatigue.
What happens to the size of a solid if you cool it down?
Probably nothing, because if you heat up a solid normally it would melt into a smaller solid or even into a liquid. So you could infer that the opposite thing would happen if you cooled down a solid (nothing would happen)

How is the speed of a wave different based on whether it is traveling through a solid a liquid or a gas?
A wave will move faster through a liquid than a gas and even faster through a solid than a liquid. This is due to that the particles are closser together in a liquid than a gas and even closer in a solid than a liquid so the wave has a tighter medium to travel through or less of a "jump" between the atoms.

What is life like as an arable farmer?
I imagine it would be very tiring to have to tend to livestock day in and day out, but very rewarding, as an animal like a cow in return would produce milk and meat for the farmer. Having been to an arable farm, I saw that a lot of work was to be done, even removing the 'waste' ;).
