in this application it means ground down as with a grinder to create a smooth flat surface. An explosion-proof rating is achieved when two smooth flat surfaces mate each other tightly but this must be a factory product - it is not something you can create in the field

What is ground roundness?

Ground round was a term used years ago referring to the leanest ground beef. The hind leg in beef is called the round (Top round, bottom round, eye of round and sirloin tip). Today if you were to read a recipe asking for ground round it does not mean you actually have a butcher ground a round roast, it just means that you need 4%-7% fat ground beef. Likewise ground sirloin would be 10%-15% fat and ground chuck would be 20% fat.


Which is the colder the ground or the sky?

By sky let's say you mean the ambient air in the lowest part of the atmosphere. In this case sometimes the ground is warmer, especially during the day and sometimes the ambient air is warmer, especially at night. It's a seasonal thing too. I we assume, by the sky you mean the upper part of the atmosphere called the upper troposphere then typically the ground is warmer.


What does hot ground mean?

Hot ground refers to soil or surfaces that have been warmed by the sun. In the context of electrical systems, hot ground can also refer to a ground connection that has higher than normal resistance, causing it to heat up when current flows through it. This condition can be dangerous and should be addressed promptly to prevent overheating and potential fire hazards.
