Chemistry

Answer:

Minimizes heat transfer

Explanation:

To keep my lunch from getting cold at the beach, a material the minimizes heat transfer will be the most desirable.

  • Such material should be modified to prevent had transfer by convection, conduction and radiation.
  • This kind of material is desirable because heat generally flows from a place of high amount to that of low amount.
  • Since the food will mostly have a temperature higher than the ambient one, it is expected that heat will flow away from the food to the environment.
  • This will make the food cold.
  • If such heat transfer is prevented, then, the food will remain hot.

How does the number of molecules in 1 mol of oxygen compare with the number of molecules in 1 mol of nitrogen?
frozen [14]

Hey there!

The number of molecules is the same.

One mole of a type of molecule is <u><em>always</em></u> 6.022 x 10²³ molecules, so no matter what the type of molecule is there will be the same amount of molecules.

The mass, volume, or other properties can be different, but the number of molecules will be the same.

Hope this helps!

A person purchases a bag of potato chips that was sealed in San Francisco, CA where the elevation is 50 feet above sea level and
bogdanovich [222]

Hello, I Am BrotherEye

Answer:

As the atmospheric pressure decreases with increase in altitude, when a sealed bag of chips is taken to higher altitude then the pressure of the gases inside the bag become greater than the outer atmospheric pressure and apply pressure on the side covering of the chips bag due to which the chips bag expand.

Explanation:

Atmospheric pressure decreases with increasing altitude. Let's assume you tie up a bag at sea level altitude (with little air inside). That air inside the bag is at 1atm as long as you're at sea level.

Now you start going up, your altitude increases and atmospheric pressure decreases (remember what I said in the beginning about atmospheric pressure decreasing with increasing altitude?).

Let's say you reach an altitude where the atmospheric pressure is 0.5atm, the force acting inside the bag which is pushing it outward is now greater than the force acting on it which is pushing it inward (1atm>0.5atm). As a result, the air inside the bag will push the sides of the bag outward, thus inflating it to a point where the pressure inside the bag becomes 0.5atm or the bag stops stretching.

For the same reason, if you bring the same bag down and take it too deep into the earth (at an altitude lower than sea level) or if you inflate the bag at a very high altitude and bring it down to sea level, it will deflate.

Best Of Luck
