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 match 1 with D.
# Answer:
1. 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 match 2 with E.
# Answer:
2. E. Charles’s law

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

### Question 4
# Brief Explanations:
Pascal's principle states that a pressure change in an enclosed fluid is transmitted undiminished to every part of the fluid and the container walls. So match 4 with G.
# Answer:
4. 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 match 5 with B.
# Answer:
5. 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 lift force. So match 6 with F.
# Answer:
6. F. Magnus effect

### Question 7
# Brief Explanations:
The Bernoulli effect states that as the speed of a fluid increases, the pressure exerted by the fluid decreases. So match 7 with C.
# Answer:
7. C. Bernoulli effect

### Question 8
# Brief Explanations:
- The kinetic theory of matter states that all molecules are in constant motion (true).
- Molecules in a warm object have more kinetic energy and move faster than in a cool object (true).
- Gases have no definite volume and expand to fill their container (true).
- The speed of molecules is related to their kinetic energy, not cohesion. In fact, faster - moving molecules are less affected by cohesion. So the statement "The faster the molecules are moving, the more they are affected by cohesion" is not true.
# Answer:
The option: 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 tubes (capillary tubes) rise above or fall below the level of the liquid outside the tube due to adhesive and cohesive forces. Meniscus is the curved surface of a liquid in a container, surface tension is the force that causes the surface of a liquid to contract, and buoyancy is the upward force on an object in a fluid. So the answer is capillarity.
# Answer:
capillarity

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