I think the last 2 questions may refer to breakage problems. Since objectives are different lengths, switching from a shorter to a longer one could damage the slide and any part of the lens that protrudes. I guess you'd want to be off the microscope and looking at the slide and objective from the side when you change, to ensure clearance. When you stow the microscope, I'd have the shortest lens in place and the tube cranked all the way up.

all things have a solid liquid and gas state. it just depends on the temperature.

Here it is again folks, our educational system failure on parade!  This is 4th grade science. 24 hours is the answer.  Please donate your tax money to me rather than your local school system.

Someone posted the exact same set of questions a few days back, either here or on the physics page - you ought to be able to find the methods in the responses. Have a look.\n\n\nBest of Luck - Mike

b. electrons\n\nI really hope you are trying to answer these first before you put them on here because although we are all certainly willing to help you, you are not going to gain anything from just having the answers given to you.  You really need to try and learn this stuff.

Did you put your entire homework assignment on here? I noticed you posted a bunch of science questions just now.\nIf you don't have your textbook handy [you really should be looking up these answers so that you can remember and understand them when you have your test/exam], go to the links below and look them up. The 1st is a down loadable physics textbook. The 2nd has animations of physics.

This is a tricky question. Perhaps reading: http://www.newton.dep.anl.gov/askasci/chem03/chem03067.htm will help.

try wikipedia or any science related source

What on earth are you posting this here for  ? It is NOT earth science for sure. And it is definitely a homework problem.\n\n------------\n\nI guess it isnt. I found it as part of some science trivia quiz.
