The absolute temperature of a gas is increased four times while maintaining a constant volume. What happens to the pressure of the gas?

The pressure increases by a factor of four

Explanation:

You can tell that temperature and pressure are directly proportional. How? Well if there is more temperature present, molecules tend to increase in kinetic energy, moving faster. Doing so the pressure increases,

Now volume also plays a role in this, the greater the volume the less the pressure as the molecules have more room to expand. Thus, they are inversely proportional. Here the volume is constant, so that makes everything simpler. As the temperature of the gas is increases 4 times, the pressure is also increased, by a factor of four.

Hope that helps!

electron microscopy and scanning tunneling microscopes gives us a greater understanding of atoms by being able to see the atom itself, and lets us see some atomic reactions.

explanation:

pure water does not conduct electricity very well. however, when certain substances are dissolved in water, the solution does conduct electricity. you can make a simple device that shows how well a solution conducts electricity. this device uses a flashlight bulb to indicate how well the solution conducts electricity. the better the solution conducts electricity, the brighter the bulb will glow.
