Option C. Predicting the boling point of a liquid, given its pressure.

The boiling point is the temperature at which the vapor pressure of a substance in liquid state equals the pressure of the environment. At this point the liquid changes into vapor. Then, we are dealing with physics properties, which means that to predict the boiling point of a liquid the chemist must have an understanging of physics.

After reading all the options represented above, I nodiced that four of them are connected to chemistry, and the only activity that was performed by a chemist is primarily based on an understanding of physics is the third option from the box. C)predicting the boiling point of a liquid, given its pressure 
while sdudying physics you often come across with such tasks where you need to find the boiling point by using the capability of reservoir with water and its size etc.

A gas occupies 25.3 at pressure of 790.5 mmHg. Determine the volume if the pressure is reduced to 8.04 mmHg
taurus [48]

Answer:

2487.51.

Explanation:

As per Boyle's law temperature remaining constant the volume of an ideal gas is inversely proportional to its pressure.

pV= k

therefore, p1V1 = p2V2

here V1 = 25.3, p2 = 8.04mm Hg

pressure p1 = 790.5 mm Hg

this means that

25.3×790.5 = 8.04V2

⇒V2= 2487.51

Hence, the required volume is, 2487.51.
