The water from inside the test tube most likely came from the blue copper sulfate crystal which is a hydrated salt.
<h3>Hydrated salts</h3>
Hydrated salts contain water of hydration.
A blue copper sulfate crystal contains water of hydration.
When heated, the water evaporates off to give an anhydrous salt which appears colorless.
The equation of the reaction is as follows:
CuSO4•5H2O -----> CuSO4 + 5H2O(g)

Metallic bonds are bonds between 2 metals. Their electrons flow around freely unlike covalent or ionic bonds.
Answer:
The answer to your question is V2 = 1.82 l
Explanation:
Data
Volume 1 = 77 l
Pressure 1 = 18 mmHg
Volume 2 = ?
Pressure 2 = 760 mmHg
Process
Use Boyle's law to solve this problem
P1V1 = P2V2
-Solve for V2
V2 = P1V1/P2
-Substitution
V2 = (18 x 77) / 760
-Simplification
V2 = 1386 / 760
-Result
V2 = 1.82 l
