Question

1. circle the letter of each statement that expresses a scientific law.

a. as the temperature of a balloon increases, the balloon expands.
b. increasing the temperature of a balloon might cause it to burst.
c. if all other variables are kept constant, the volume of a gas increases as the temperature increases.
d. sometimes increasing the temperature of a gas causes the gas to expand.
collaboration and communication

1. several scientists working together to solve a problem is _______________.
2. is the following statement true or false? scientists from different disciplines may need to work together on a problem because the problem is too complex for one person to solve.
3. exchanging ideas about science is called _______________.
4. how are journals helpful to scientists?
5. is the following statement true or false? experts in an author’s field review articles before they are published in a journal.

Explanation:

Question 12

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

• Option a: Describes a balloon's expansion with temperature but is a specific example, not a general law.
• Option b: Uses "might", indicating uncertainty, not a law.
• Option c: States the relationship between gas volume and temperature with constant variables, which is Charles's Law (a scientific law).
• Option d: Uses "sometimes", indicating inconsistency, not a law.

When several scientists work together to solve a problem, this is called collaboration.

Complex problems often require diverse expertise, so scientists from different disciplines may need to collaborate as one person can't have all necessary knowledge. Thus, the statement is true.

Answer:

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