Answer:
When the person poured water into it, slowly and steadily that quantity of water also got into the bucket and it occupied some amount of space inside. In this case, there will not be any change of shape in the rock when it is inside, as compared to what it was when it was outside.
Explanation:
Answer:
0.24V
Explanation:
First we must obtain the ionic strength of the solution I as shown in the image attached. This ionic strength can now be used to obtain the activity coefficient of the ions in solution by substitution of the value of the ionic strength obtained previously and the charge of the ion (Cu2+) into the equation for activity coefficient.
The activity of an ion is defined as the product of its activity coefficient and its concentration. This activity of copper II ion is now substituted into the Nernst equation to obtain the equilibrium potential required in the question.
Physical change will not change the composition of a substance.
