Why does the can crush when placed in cold water?
When a can is placed in cold water, the air inside the can cools down and contracts, creating a lower pressure inside the can compared to the outside. The higher pressure outside the can then crushes the can as it tries to equalize the pressure inside and outside.
What are the types of solution of osmosis?
The types of solutions in osmosis are hypertonic, hypotonic, and isotonic. In a hypertonic solution, the concentration of solute is higher outside the cell compared to inside, causing water to move out of the cell. In a hypotonic solution, the concentration of solute is higher inside the cell compared to outside, causing water to move into the cell. In an isotonic solution, the concentrations of solute inside and outside the cell are equal, so there is no net movement of water.
Which of the subatomic particles has a negative charge is found outside of the nucleus and has almost no mass?
The subatomic particle that fits this description is the electron. Electrons have a negative charge, are found outside of the nucleus in electron shells, and have a very small mass compared to protons and neutrons.
How can the results of the can crushing experiment be used to demonstrate the effects of air pressure?
The results of the can crushing experiment can be used to show how changes in air pressure can cause the can to collapse. By heating the can and then quickly cooling it, the air inside the can condenses, creating a lower pressure compared to the outside air. This pressure difference causes the can to crush as the higher external pressure pushes in on it. This experiment illustrates how air pressure can have a significant impact on objects in our environment.
What are the advantages and limitations of column chromatography over thin layer chromatography?
TLC. The mobile phase is a liquid, the stationary phase is a solid. Useful for seperating and comparing mobility of solids and some liquids dissolved in the mobile phase by their affinities to the solid phase relative to the mobile phase. GLC. The mobile phase ia s gas, the stationary phase is a liquid on a solid support. same concept as TLC. useful for seperating gases by their affinities to the stationary phase...the mobility can then be compared to known compounds for possible identification.
What is a stationary observer?
A stationary observer is an individual or point of reference that is not moving or changing position in relation to the objects or events being observed. This observer serves as a fixed frame of reference to study the motion and properties of other objects in motion.
Why do objects inside the car appear to be stationary when compared to the objects outside of the car?
Think of the car as a mobile container, holding items being transported, the item doing the transporting is in motion, and attached to the inside are the items being moved. so the total speed of the items being moved is the same as the item/vehicle doing the moving. Because the vehicle in motion is travelling in a different direction to the location being travelled, this gives you the result (the items in the vehicle are stationary relative to the motion of the vehicle in use).
Why does a train in which you are sitting appears to move while it is at rest?
Your brain is used to perceiving motion relative to stationary objects, such as the buildings and landscape passing by. When sitting in a stationary train, it can create the illusion that the train is moving if you observe things outside the window passing by. This phenomenon is known as "relative motion."
What are stationary objects a result of?
Stationary objects are a result of the balance between external forces like gravity, friction, and opposing forces within the object itself. When these forces are in equilibrium, the object remains still without any change in position.
Jeff is in stationary school bus. which is the best reference point for him to use to determine when the bus starts to move?
The exterior of the bus or objects outside the bus would be the best reference point for Jeff to use to determine when the bus starts to move. By observing the movement of objects through the bus windows or changes in the view outside, Jeff can accurately gauge when the bus begins to move.
Is it worth buying a stationary bike if it is expensive and boring?
Yes, a stationary bike would be worth buying. A stationary bike would be good during the winter when there is snow on the ground and the weather is too cold to use a bike meant for outside. It would also be good in the summer, when it is too hot to be outside. Many stationary bikes come with workouts that can be pre-programmed into them.
Which gives you a frame of reference for your speed when you are riding train?
The landscape passing by outside the train window gives you a frame of reference for your speed when riding a train. You can also gauge your speed by looking at stationary objects outside the train, such as poles or buildings. Additionally, the sensation of motion and the train's vibrations can provide cues about your speed.
Where can you find Christmas stationary?
Christmas stationary can be found in most major department stores in the Christmas season. For example, in the UK, Christmas stationary can be found in House of Fraser or John Lewis. Outside of the Christmas season, then Christmas stationary will only likely be found in Christmas shops or online.
If you are seated in a train give two ways it may appear that you are still moving?
If the train next to you moves, it might appear that your train is also moving. Additionally, if you focus your gaze on objects outside the window that are stationary, it can create an illusion that your train is moving.
When you look through a window why can you see objects outside?
You can see objects outside through a window because light from the objects outside passes through the window and enters your eyes. This allows your eyes to detect the shapes and colors of the objects, creating the perception of the scene outside.
What does force applied to a stationary object give the object?
Newton's First Law of Motion states that objects will remain in their current state of motion (whether stationary or travelling at a constant velocity) unless an outside force acts on them. If he force you are mentioning here causes the net force to become unbalanced, then the force will cause the object to accelerate until the forces are balanced and it reaches either a constant speed, or the opposing force causes it to decelerate and eventually become stationary.
If inside the earth objects is called terrestrial. What do you called the objects outside the earth?
ET (Extra terrestrial)
