The boiling point<span> is the temperature at which the vapor pressure of the liquid equals the surrounding pressure. At this temperature, liquid gets converted into vapour phase.

Now, if one goes to higher heights, i.e. mountains, pressure decreases. Since, pressure decreases the boiling point also decreases. Hence, if heating rate is same, the time needed to reach the boiling point will decrease.

Okay!
8.50molH, represents 8.50 moles of Hydrogen gas!
To convert from moles to volume multiply it by the ratio of L/molH
mol of anything in a conversion problem is always 1 unless you are going to an unknown! Try to memorize this, but the number you always put in for the # of liters in a conversion problem is 22.4L (L is a measure of volume)
8.50molH * (22.4 L/ 1 molH)
190.L of Hydrogen Gas.
Hope that helped!
