d correct ans is A
viscosity decreases wit an increase in temperature but increases wit an increase in d pressure of d system

In an experiment to determine terminal velocity, as the pressure increases, the viscosity of a liquid would generally remain constant or slightly increase.
Viscosity is a measure of a fluid's resistance to flow, and it is influenced by factors such as temperature, pressure, and the composition of the fluid. However, for most liquids, the effect of pressure on viscosity is small, and its influence is usually negligible.
In some cases, an increase in pressure can cause a slight increase in viscosity due to the compression of the fluid's molecules, which can increase their interactions and slow down the fluid's flow. However, this effect is generally only significant at very high pressures.
Therefore, the correct answer is D. remains constant or slightly increases

how will sum1 understand.... i checked past question dey said its A....also d same past question said d ansa is C...now myschool is saying D....hu will i follow oo?....u guyz should plss help na

The ans is A
viscosity depend on presure.increase in pressure lead to increace viscosity of a fluid i.e gas and liquid

Okay, let's break down why D) remains constant would be the right answer in this particular question, keeping it simple!
Imagine you have a liquid, like water, in a container. Now, you start pushing down on it, increasing the pressure.
* Viscosity is how "thick" or "runny" a liquid is. Honey is very viscous, while water is less viscous.
* In this question, it seems we're looking at a situation where the pressure change doesn't really change how runny the liquid is.
* Think of it like this: if you gently press on a bottle of water, it still flows pretty much the same. The pressure change didn't make it suddenly thick like honey.
So, in this case, the question wants you to pick the answer that says the "runniness" (viscosity) stays the same, even when you change the pressure. That's why D) remains constant is the best choice.
It's like saying, "Even if I push a little harder, the water still flows the same way."

this is sooo annoying
in 2004 this same question was repeated and this same website said the viscosity increases
this is why i have trust issues

same question from 2004 but different answer in 2006
the answer is a increase in pressure leads to increase in viscosity

vicosity of liquid does not depend on pressure while that of gas is depend on pressure

For many liquids, as pressure increases, their viscosity tends to increase. This is because higher pressure forces the molecules closer together, which enhances intermolecular forces and resistance to flow.

In an experiment to determine terminal velocity, as the **pressure increases**, the **viscosity of a liquid** behaves as follows:
- **For most liquids**: The viscosity **increases** with rising pressure because the amount of free volume in the internal structure decreases due to compression. As the pressure increases, the intermolecular distance decreases, leading to an increase in the resistance to the flow of the liquid .
- **For gases**: The viscosity of an ideal gas is **independent of pressure**, and this is approximately accurate for real gases. In gases, viscosity arises mostly because of the transfer and exchange of molecular force. However, under extreme conditions (e.g., low temperatures and/or high pressures), the ideal gas model may break down, and viscosity could exhibit some pressure dependence .
Therefore, the correct answer is **D: remains constant**. In most practical circumstances, viscosity remains unaffected by pressure changes, but extreme conditions can lead to variations

The answer is D. Normally viscosity is independent of pressure but will increase under extreme pressure.
