Explanation:

Question 12

A scientific law is a statement that describes a natural phenomenon consistently under specific conditions.

• Option a: Describes a specific case (balloon) but not a general law for gases.
• Option b: Is a possibility, not a law.
• Option c: States the relationship between gas volume and temperature (Charles's Law) with controlled variables, a scientific law.
• Option d: Uses "sometimes," which is not consistent like a law.

When multiple scientists work together to solve a problem, it is called collaboration (scientific collaboration).

Complex problems often require diverse expertise from different scientific disciplines, so scientists from different fields may need to collaborate. Thus, the statement is true.

Answer:

c. If all other variables are kept constant, the volume of a gas increases as the temperature increases.
