The correct answer and explanation is:<\/mark><\/strong><\/p>\n\n\n\n
Correct Answer:<\/strong><\/h3>\n\n\n\n
\n
When a liquid is under pressure, its volume decreases<\/strong>.<\/li>\n\n\n\n
When a liquid is under pressure, its density increases<\/strong>.<\/li>\n<\/ul>\n\n\n\n\n\n\n\n
Explanation:<\/strong><\/h3>\n\n\n\n
The behavior of liquids and gases under pressure is governed by fundamental principles of fluid mechanics and molecular behavior.<\/p>\n\n\n\n
\n
Liquids Under Pressure:<\/strong>\n
\n
Unlike gases, liquids are incompressible<\/strong>, meaning they do not change volume significantly when pressure is applied. However, under extreme<\/strong> pressure, a very small decrease in volume can be observed.<\/li>\n\n\n\n
The molecules in a liquid are already closely packed together, so when pressure is applied, the intermolecular spaces reduce slightly, leading to a decrease in volume<\/strong>.<\/li>\n\n\n\n
Since density is defined as mass per unit volume<\/strong> (\u03c1=mV\\rho = \\frac{m}{V}), a decrease in volume<\/strong> results in an increase in density<\/strong>.<\/li>\n<\/ul>\n<\/li>\n\n\n\n
Gases Under Pressure:<\/strong>\n
\n
Gases, on the other hand, are highly compressible<\/strong> because their molecules are far apart and can be forced closer together.<\/li>\n\n\n\n
When pressure is applied to a gas, its volume decreases significantly<\/strong>, following Boyle\u2019s Law (P1V1=P2V2P_1 V_1 = P_2 V_2), which states that at constant temperature, pressure and volume are inversely proportional.<\/li>\n\n\n\n
As the volume of a gas decreases, its density increases, as the same number of gas molecules occupy a smaller space.<\/li>\n<\/ul>\n<\/li>\n\n\n\n
Key Difference Between Liquids and Gases:<\/strong>\n
\n
A liquid resists compression<\/strong> due to strong intermolecular forces, while a gas can be compressed easily<\/strong> because of the large spaces between molecules.<\/li>\n\n\n\n
This is why gases are used in pneumatic systems, while liquids are used in hydraulic systems, where incompressibility is an advantage.<\/li>\n<\/ul>\n<\/li>\n<\/ol>\n\n\n\n
Thus, the correct answer is:<\/p>\n\n\n\n
\n
Volume decreases when a liquid is under pressure.<\/strong><\/li>\n\n\n\n
Density increases when a liquid is under pressure.<\/strong><\/li>\n<\/ul>\n\n\n\n
Now, I’ll generate an image illustrating this concept.<\/p>\n\n\n\n
