Boiling point
i hope this helps.
Answer: I believe it is critical mass
Explanation:
Within the visible range of light, red<span> light waves are scattered the least by atmospheric gas molecules. So at sunrise and </span>sunset, when the sunlight travels a long path through the atmosphere to reach our eyes, the blue light has been mostly removed, leaving mostly red<span> and yellow light remaining.</span>
No, because boats and other mechanical vehicles can spill gas and oil into the freshwater. if the freshwater is scarce already, we should not contaminate it more by risking the gas and oil spills.
Answer:
The average pressure in the container due to these 75 gas molecules is 
Explanation:
Here Pressure in a container is given as

Here
- P is the pressure which is to be calculated
- ρ is the density of the gas which is to be calculated as below

Here
mass is to be calculated for 75 gas phase molecules as

Volume of container is 0.5 lts
So density is given as

is the mean squared velocity which is given as

Here RMS is the Root Mean Square speed given as 605 m/s so

Substituting the values in the equation and solving

So the average pressure in the container due to these 75 gas molecules is
