Answer: The average kinetic energy is proportional to the absolute temperature of the gas. Gas particles are in random motion. Gas particles have no volume. And the collisions between gas particles are elastic.
Explanation: I heard this question before, I think. Hope this helps!
Answer:Carbon dioxide
Explanation:Carbon dioxide molecules are heavier than air. Because of this, they push the oxygen and other molecules in the air out of the way as they sink down over the flame and candle. When oxygen is pushed away from the wick, it can’t react with the wax anymore. This makes the flame go out.
Next time you blow out a candle, think about what your breath is doing. Why do you think blowing on a candle flame makes it go out?
Because atomic number equals protons and electrons
8-electrons
8-protons
Protons+neutrons=mass
8+8=16 and 8+10=18
8-Neutrons for 16
10- Neutrons for 18
Answer : The length of the ramp to the nearest inch will be, 129.49
Step by step explanation :
As we know that,
In the given image, the value of 
(the angle between the base and the hypotaneous) is 
and the value of perpendicular is 18 inch.
Now we have to calculate the value of the hypotaneous by using above expression, we get
The hypotaneous is equal to the length of the ramp = 129.49 inch
Therefore, the length of the ramp to the nearest inch will be, 129.49
