What is surface tention?
Surface tension is a property of a liquid that causes its surface to behave like an elastic membrane. It is due to the cohesive forces between the liquid molecules which results in the liquid trying to minimize its surface area. This leads to effects like droplets forming or insects being able to walk on water.
Assumption of kinetic theory of gas?
The volume occupied by gas molecules is negligible when compared to volume occupied by the gas.The collisions between gas molecules-gas molecules and gas molecules-walls of the container are perfectly elastic.
When gas molecules collide what is the collision is considered?
When gas molecules collide, the collision is considered to be an elastic collision. In an elastic collision, both momentum and kinetic energy are conserved, meaning that the total energy before and after the collision remains constant. This behavior is a fundamental characteristic of ideal gas behavior, where interactions between molecules are minimal and only occur during collisions.
Why gas molecules are perfectly elastic?
Gas molecules are perfectly elastic because they do not lose any kinetic energy when they collide with each other or the walls of their container. This means that their total energy remains constant, leading to elastic collisions. Additionally, gas molecules are considered point masses with negligible volume, contributing to their elastic behavior.
Why gas molecules are elastic?
Gas molecules are elastic because they possess kinetic energy, allowing them to move and collide with other molecules. When gas molecules collide with each other or with the walls of their container, they transfer energy back and forth, resulting in elastic collisions that maintain constant pressure and volume within the gas.
How are the molecules arranged in gas?
In a gas, molecules are arranged randomly and move freely in all directions. They have high kinetic energy and collisions between molecules are elastic. The distance between molecules is large compared to the size of the molecules themselves.
What is surface tention?
Surface tension is a property of a liquid that causes its surface to behave like an elastic membrane. It is due to the cohesive forces between the liquid molecules which results in the liquid trying to minimize its surface area. This leads to effects like droplets forming or insects being able to walk on water.
Why a drop of water put on a glass plate spreads?
When a drop of water is placed on a glass plate, it spreads out due to surface tension. Surface tension is the property of a liquid that causes its surface to behave like a thin elastic sheet. The water molecules at the surface of the drop are pulled inward by the cohesive forces between water molecules, causing the drop to spread out to minimize its surface area.
Assumption of kinetic theory of gas?
The volume occupied by gas molecules is negligible when compared to volume occupied by the gas.The collisions between gas molecules-gas molecules and gas molecules-walls of the container are perfectly elastic.
What are gas molecules colliding with no change in total energy?
When gas molecules collide without a change in total energy, it means that the collisions are elastic. In an elastic collision, the kinetic energy of the gas molecules before and after the collision remains constant. This type of collision conserves energy and momentum.
What is the source for elastic energy?
Elastic energy is stored in an object when it is deformed or stretched. This energy is due to the potential energy stored in the bonds between atoms or molecules within the object, which can be released when the object returns to its original shape.
Which property of water allows it to form droplets when in liquid form?
The property of water known as surface tension allows it to form droplets when in liquid form. Surface tension is caused by the cohesive forces between water molecules, which makes the surface of water behave like a thin, elastic film that minimizes surface area and holds the droplet shape.
What will be the total higher quantity do in the elastic inelastic and unit-elastic?
The midpoint between elastic and inelastic is unit elastic
Difference between elastic and inelastic demand?
difference between elastic and inelastic demand
What is Difference between elastic limit and proportional limit?
Proportionality limit is the point upto which the stress remains directly proportional to strain whereas elastic limit is the point upto which the material remains elastic ie. if the stress is removed within elastic limit, then the material will regain its original shape and size.
An elastic force that stretches or pulls on the molecules in matter is?
An elastic force that stretches or pulls on the molecules in matter is known as tension. This force occurs when an object is being stretched or pulled in opposite directions.
What are elastic forces produced by?
Elastic forces are produced by a material's ability to deform reversibly in response to an external force. When a material is stretched or compressed, the elastic forces arise from the bonds between atoms or molecules within the material attempting to return to their original positions, resulting in a restoring force that opposes the deformation.
