The volume of a gas with an initial pressure of 380 mmHg atm increases from 5.0 L to 8.0 L. What is the final pressure of the gas, in atm, assuming no change in moles or temperature? A) 238 atm
B) 2.4 atm
C) 0.31 atm
D) 0.80 atm
E) 8.0 atm

Explanation:

The new pressure can be found by using the formula for Boyle's law which is

Since we are finding the new pressure

From the question

760 mmHg = 1 atm

380 mmHg = 0.5 atm

We have

We have the final answer as

Hope this helps you

the best answer is d because the strong cohesion is caused by the ability of water molecules to undergo hydrogen bonding.

a is incorrect because when water solidifies, it becomes   ice, which expands and occupies a bigger volume for the same mass of water in its liquid state.

b is incorrect because water has high surface tension. besides bonding to itself it hydrogen bonds to other molecules at the top decreasing possibility for breaking of attractive forces.

c is incorrect because the water molecule has oxygen which is highly electronegative and so pulls the electron pair towards itself creating a dipole moment, making the molecule polar.

e is incorrect because water has strong adhesion, ability to stick to other molecules such as glass because of this molecules having stronger hydrogen bonding than water.
