15 POINTS! Yes, more science... What kind of tool can you use to view atoms and molecules up close?

Answers

Generally, molecules are hard to see up close, that is why models are made. So that people can see the structure of atoms and how the nucleus looks. 

Other then a model, an transmissional electron microscope is used to look at atoms up close. 
Well, its a microscope pretty much. But they are called "electron microscopes". But yea just a microscope. ...... oh yeah also a scanning tunneling microscope :)

A student has the following equipment - copper wire, nail made of iron,a battery, paperclips.How can he make an electromagnet and use it to separate a mixture of small pieces of copper and iron?

please help

Answers

The first step would be to create an electromagnet. You can create an electromagnet by winding a copper wire around the nail, the connect both ends to the battery. A current would start flowing around the nail through the wire, creating an electromagnet with its own magnetic field. Next, bringing the electromagnet to the mixture of copper and iron would slowly attract the pieces of iron (as copper is weakly magnetic). Do this slowly and the iron pieces would all slowly be separated from the copper pieces.

When car tires are on hot pavement for too long, the pressure inside will ___________ and the volume within the tire will _____________. A) increase; decrease due to deflation B) decrease; remain unchanged C) increase; increase and possibly result in a blowout D) increase; remain unchanged as long as the temperature is constantly rising

Answers

When the car is driven at high speed for a long time on rough pavement,
the tires and the air inside them heat up. 

That causes the air pressure inside the tires to increase, and the increased
pressure tries to make the tires bigger (they ARE made of rubber, after all).

Normally, the tires do expand a little.  But if this goes on for too long, or
if there's a weak spot on the tire, a blowout is possible.
