A The volume and the shape stay the same.
B The volume increases to fill the new container, but the shape stays the same.
C The volume stays the same, but the shape changes to fit the new container.
D The volume and the shape change to fill the new container.

2 Which of these correctly defines the pH of a solution?
A the negative log of the hydronium ion concentration
B the log of the hydronium ion concentration
C the negative log of the hydroxide ion concentration

2) A
I just took the quiz
Hope this helps you and others in the future!

Answer 2

Answer 1 : The correct option is C.

Explanation :

The property of liquid is, they have fixed volume but do not have fixed shape. when a liquid is transferred from one container to another then the volume remains the same, but the shape changes according to the shape of the container.

Answer 2 : The correct option is A.

Explanation :

pH : It is defined as the negative logarithm of the hydronium ion concentration.

The expression of pH is,

`pH=-log[H_3O^+]`
