It is totally not batholith, It is written in the section that it is Extrusive.
The mass of the system consisting of the ice cube and the plastic cup will remain 5 grams even after the ice completely melts. This is because of the Conservation of Mass principle, which states that mass is not lost during a phase change.
The principle operating in this scenario is called the Conservation of Mass. In this specific context, this principle means that the mass of an object or a system of objects will remain the same regardless of the changes it may undergo, as long as no mass enters or leaves the system. In the case of an ice cube melting, although the physical state (phase) of the water changes from solid (ice) to liquid (water), its mass does not change.
So when an ice cube that weighs 5 grams (along with the cup) melts, it turns into an equivalent mass of liquid water. That means even after the ice has completely melted into water, the mass of the water and the plastic cup will still be 5 grams.
This is because during the phase change, only the state of the matter is altered (from solid to liquid), not its mass. The water molecules in the ice rearrange themselves and move apart during melting allowing the ice to become liquid water, but the number of molecules and thus the mass stays the same.

Answer:
A pH less than 7 is an acid, with number 1 indicating stronger acids
Explanation:
The pH scale has a range of 1 to 14. The following has been concluded on the pH scale:
1. Between 1 and 6 indicates an acid solution.
2. 7 indicates a neutral solution
3. Between 8 and 14 indicates an alkaline or basic solution.
Now with these information, we can answer the above questions as follow:
A pH less than 7 is an acid, with number 1 indicating stronger acids
A pH less than 7 is an acid. Lower pH values mean stronger acids.
A pH less than 7 is considered an acid. The pH scale measures the concentration of hydrogen ions in a solution, therefore a lower number on the scale indicates a higher concentration of hydrogen ions and consequently a stronger acid. For example, lemon juice, with a pH of around 2, is much more acidic than black coffee, which has a pH of about 5.
