Accepted Answer

### Question 1
# Brief Explanations:
This describes Boyle's Law, which states that for a fixed amount of gas at constant temperature, pressure and volume are inversely proportional. So the term matches with D. Boyle's law.
# Answer:
D. Boyle's law

### Question 2
# Brief Explanations:
Charles's Law states that at constant pressure, the volume of a gas is directly proportional to its absolute temperature. So this matches with E. Charles's law.
# Answer:
E. Charles's law

### Question 3
# Brief Explanations:
Amontons's law (also known as Gay - Lussac's law) states that at constant volume, the pressure of a gas is directly proportional to its absolute temperature. So this matches with A. Amontons's law.
# Answer:
A. Amontons's law

### Question 4
# Brief Explanations:
Pascal's principle states that a pressure change in an enclosed fluid at rest is transmitted undiminished to every portion of the fluid and the walls of the containing vessel. So this matches with G. Pascal's principle.
# Answer:
G. Pascal's principle

### Question 5
# Brief Explanations:
Archimedes' principle states that the buoyant force on an object submerged in a fluid is equal to the weight of the fluid displaced by the object. So this matches with B. Archimedes' principle.
# Answer:
B. Archimedes' principle

### Question 6
# Brief Explanations:
The Magnus effect is the phenomenon where a spinning object moving through a fluid creates a pressure difference that results in a lateral force (lift). So this matches with F. Magnus effect.
# Answer:
F. Magnus effect

### Question 7
# Brief Explanations:
The Bernoulli effect states that as the speed of a moving fluid (liquid or gas) increases, the pressure within the fluid decreases. So this matches with C. Bernoulli effect.
# Answer:
C. Bernoulli effect

### Question 8
# Brief Explanations:
- The kinetic theory of matter states that all molecules are in constant motion, so the first statement is true.
- Molecules in a warm object (higher temperature) have more kinetic energy and move faster than in a cool object, so the third statement is true.
- A gas has no definite volume and expands to fill its container, so the fourth statement is true.
- Cohesion is the attraction between molecules of the same substance. The speed of molecules' motion is related to kinetic energy (temperature), not directly to cohesion in the way that "the faster the molecules are moving, the more they are affected by cohesion" is incorrect. So the false statement is "The faster the molecules are moving, the more they are affected by cohesion."
# Answer:
The faster the molecules are moving, the more they are affected by cohesion.

### Question 9
# Brief Explanations:
Capillarity is the phenomenon where liquids in narrow (thin) tubes rise above or fall below their normal levels due to the combination of adhesive and cohesive forces. Meniscus is the curved surface of a liquid in a tube, surface tension is the force that causes the surface of a liquid to behave like a stretched elastic membrane, and buoyancy is the upward force on an object in a fluid. So the correct answer is capillarity.
# Answer:
capillarity

### Question 10
# Brief Explanations:
The SI unit of pressure is the pascal (Pa). Atmosphere is a non - SI unit of pressure, joule is the SI unit of energy, and torr is also a non - SI unit of pressure. So the correct answer is pascal.
# Answer:
pascal
