Is there any difference between mass and inertia? Is the word "inertia" necessary, or could it be eliminated from physics books?

I have tools that are made of metal and very reflective and shiny. If shiny objects reflect light waves, how is it that my tools get too hot to touch if I leave them in the sun (in the summer months)? Are the tools absorbing other forms of EM radiation?

So let's say the sun warmed a sidewalk abutting black pavement and the air surrounding it all. And then the sun goes down. Actually, for this scenario let's say the sun disappears. The pavement, sidewalk and air no longer have the warming energy of the sun and would then radiate (lose)...

I have a question regarding heat transfer/ heat loss. When the sun goes down, let's say in December, is it possible that some objects lose heat (through radiation) at a quicker rate than other objects? If so, colder objects would lose heat, or emit radiation, to its surroundings (warming its...
