Admin What is the example of closed system?
A closed system allows only energy transfer but no transfer of mass. Example: a cup of coffee with a lid on it, or a simple water bottle.
How do you tell if a system is closed or open?
Systems and surroundings
- An open system can exchange both energy and matter with its surroundings.
- A closed system, on the other hand, can exchange only energy with its surroundings, not matter.
- An isolated system is one that cannot exchange either matter or energy with its surroundings.
Which of the following is an example of open system?
An example of an open system is a beaker full of water. In a beaker full of water the water molecules can escape the beaker and the heat energy from the beaker and the surrounding can exchange with each other. So, the correct answer is “Option A”.
What will happen if you fill a bicycle tube with air?
If we go on filling more and more air into bicycle tube with a pump, then ultimately the air pressure in the bicycle tube will increase too much due to which the bicycle tube may even burst. The atmosphere contains a tremendous amount of air. Air has weight, so the atmosphere consisting of tremendous amount of air has enormous weight.
Why do bicycle tyres feel hard when filled with air?
When we fill air into the bicycle tube, then the air molecules inside the tube collide with the walls of the tube and exert air pressure. This air pressure exerted from inside, inflates the bicycle tube, So, it is the pressure exerted by air filled in a bicycle tube which keeps the tube tight and makes the bicycle tyre feel hard.
What is the difference between open and closed end of tube?
The closed end of a tube is an antinode in the pressure (or a node in the longitudinal displacement). The open end of a tube is approximately a node in the pressure (or an antinode in the longitudinal displacement). Tubes with two open ends
What is the frequency of a tube with two open ends?
For a tube with two open ends all frequencies f n = nv/ (2L) = nf 1, with n equal to an integer, are natural frequencies. Tubes with one open and one closed end The longest standing wave in a tube of length L with one open end and one closed end has a displacement antinode at the open end and a displacement node at the closed end.
