Why it is difficult to lift a large stone on the surface of the earth but easy to lift a smaller one?
Large stone has more mass compare to a small one. And mass is directly proportional to weight where 'g' is constant for every object on earth. As a result larger stone has more weight than that of smaller. That's why it is difficult to lift larger stone on the surface of the earth but easier to lift a smaller one.
How do you separate insoluble substances from a liquid?
Gently force the liquid through a permeable membrane (such as filter paper)whose pores are smaller than the particle size of the insoluble solid you wish to remove from the solution.
Does the boiling point of a liquid decreases increases or stay the same if the intermolecular force increases?
Generally, the boiling point of a liquid increases if the intermolecular force, i.e. pressure, increases.
How do you find the net force when two forces act in opposite directions?
by subbracting
Is Buoyancy an upward force exerted by a fluid on a body placed in the fluid?
False. It is an upward force, that (partly) counteracts the downward force of gravity for objects within a liquid. It is related to the resistance (to displacement) by the liquid molecules.
What is difficult to compress or force into a a smaller space?
Materials that are rigid and lack flexibility, such as solid objects like rocks or metals, are difficult to compress or force into a smaller space. Additionally, substances that are tightly packed, like dense gases or liquids, can also be challenging to compress.
Does packaged water need ullage?
Since liquids when expanding will generate some force, and the liquid cannot compress, it would be dangerous to not allow some ullage space in the container above the liquid. Some gas above the liquid can easily compress, and absorb the (thermal) expansion of the liquid.
Which states of matter are virtually incompressible to smaller volume?
You can force gas into a smaller volume, and it will expand to fill any container you put it in.
What force is used in force meters?
Newtonian force The amount of force is measured by its ability to stretch or compress a spring.
What is the other word for a push or a pull?
compress
What is the attractive force of a liquid?
The attractive force of a liquid is called cohesion, which is the force that holds the liquid molecules together. This force is responsible for creating the surface tension of a liquid and allows liquids to form droplets or maintain their shape.
Does alcohol affect buoyancy?
Of course it does. Alcohol has a density of around 0.8 g/ml while water is pratically 1. Using old Archimedes the force from buoyance is equal to the weight of the liquid that is "moved"by the object being floated - so smaller density, smaller force.
What is the relationship of buoyant force and density of liquid?
The buoyant force on an object submerged in a liquid is equal to the weight of the displaced liquid. The density of the liquid affects the buoyant force as denser liquids will exert a greater buoyant force on an object compared to less dense liquids.
What is the relationship between density of a liquid and the buoyant force exerted on the mass?
The buoyant force exerted on an object immersed in a liquid is equal to the weight of the liquid displaced by the object. The buoyant force is directly proportional to the density of the liquid. Therefore, the denser the liquid, the greater the buoyant force it exerts on the object.
What force opposes nuclear fusion in the sun?
The force that opposes nuclear fusion in the sun is gravity. Gravity is constantly pulling inward, trying to compress the sun's material into a smaller space. The outward pressure from nuclear fusion counteracts this force, creating a delicate balance that maintains the sun's stability.
Is buoyant force a contact force?
The buoyant force is a contact force, exerted by contact with a liquid that displaces the liquid within a gravity field. No contact, no force.
What is the upward force in the liquid?
The Buoyant Force
