ANS:A - binding energy of atoms.

The difference in the properties of a substance in three states of matter primarily depends upon the difference in intermolecular forces. Intermolecular forces are the forces of attraction or repulsion between molecules or atoms in close proximity to each other. These forces play a significant role in determining the physical properties of substances, including their state of matter (solid, liquid, or gas). In solids, intermolecular forces are strong enough to hold the particles closely packed together, resulting in a fixed shape and volume. In liquids, the intermolecular forces are weaker than in solids, allowing particles to move past each other, leading to a definite volume but not a fixed shape. In gases, intermolecular forces are relatively weak, allowing particles to move freely and independently of each other, resulting in neither a definite shape nor volume. While binding energy of atoms and molecular shape can influence the behavior of substances, it is the intermolecular forces that primarily dictate the differences observed in the properties of substances in their different states of matter. Therefore, the correct answer is: difference in intermolecular forces.

ANS:A - partial pressure of vapour in the mixture.

Partial pressure of vapor in a mixture refers to the pressure that the vapor would exert if it alone occupied the volume of the entire mixture at the same temperature. In other words, it's the pressure contributed by the vapor molecules to the total pressure of the mixture. Consider a mixture of gases, such as air, which contains various components including water vapor. Each gas in the mixture exerts its own pressure, known as its partial pressure. The partial pressure of the vapor is determined by its concentration in the mixture and follows Dalton's law of partial pressures, which states that in a mixture of non-reacting gases, the total pressure is the sum of the partial pressures of the individual gases. For example, if you have a closed container with air and water vapor, the total pressure inside the container is the sum of the partial pressure of the air and the partial pressure of the water vapor. Mathematically, the partial pressure of a component in a mixture can be calculated using the following formula: 𝑃partial=𝑋component×𝑃totalPpartial​=Xcomponent​×Ptotal​ Where:

• 𝑃partialPpartial​ is the partial pressure of the component,
• 𝑋componentXcomponent​ is the mole fraction of the component in the mixture,
• 𝑃totalPtotal​ is the total pressure of the mixture.

ANS:A - pseudoplastic

Rubber latex is an example of a pseudoplastic fluid. Here’s why:

• Pseudoplastic Fluid: Pseudoplastic fluids, also known as shear-thinning fluids, are fluids whose viscosity decreases with increasing shear rate. In other words, as the fluid is subjected to higher rates of shear stress (such as during stirring or flowing through a pipe), its viscosity decreases, allowing it to flow more easily. Rubber latex exhibits this behavior—it becomes less viscous and flows more readily when agitated or processed.
• Bingham Plastic: Bingham plastics require a minimum stress, called the yield stress, to start flowing. Rubber latex does not exhibit this behavior; it flows continuously without a yield stress.
• Dilatant: Dilatant fluids, or shear-thickening fluids, increase in viscosity with increasing shear rate, which is the opposite behavior of rubber latex.
• Newtonian: Newtonian fluids have a constant viscosity regardless of the shear rate. Water is an example of a Newtonian fluid.
