HELP PLEASEEE If you make a narrow opening with your mouth and blow air out of your lungs it will feel cool.
This is because the air is able to expand as it passes between your lips. This demonstrates which relationship?

a) volume decreases & temperature increases

b) pressure increases & temperature decreases

c) volume increases & temperature decreases

in scientific notation, the value of the  speed of light in a vacuum

  will be written as 2.995 * 10^8. when this value is represented in the form of

  a * 10^b, then, a = 2.995 and b = 8.

the value of the speed of light in a vacuum given above can also be rounded up to approximately 300000000. in this case, the scientific notation will be written as 3 *10^8.

because of all the things that happen around the us, many people get into arguments which sadly could get physical, but we should actually make a change for that.

1. a)c-14 has two more protons

2. d)they have different numbers of protons, neutrons, and valence electrons; they are all gases at room temperature.

3. c) iron and nickel.
