Which activity performed by a chemist is primarily based on an understanding of physics?

a)predicting the properties of an element based on its placement on the periodic table

b)writing noble gas configurations for an element

c)predicting the boiling point of a liquid, given its pressure

d)predicting the acidic or basic nature of a substance based on its ph

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. 

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.

I’d have to say no because without oxygen in the water the fish would all be dead. so if you want to fish for dead fish, pick the ponds with the lowest oxygen concentrations.
