The energy is conserved by the " law of conservation of energy" . It states that energy can be neither created nor be destroyed. Then a question may arise that if there is no change in the amount of energy, then why do people often say that energy should be conserved ...... energy is wasting....... we must prevent it? Energy is a finite resource. The materials we derive energy from (oil, coal, electricty, ect.) can also harm the environment. By conserving energy you help to save parts of the environment. There are many ways to conserve energy. The most obvious is to not waste it. This can easily be done by shurring off lights when you leave a room, or turning off the computer or TV when it is not being directly used. Some other ways would be to recyle (it takes more energy to produce new cans, for example, than to re-use recycled ones) or re-use bottles or bags so that energy doesn't need to go into making new ones and the others aren't wasted.

∙ 12y agoThe First Law of Thermodynamics states that the amount of energy in a closed system remains constant. In other words, you can neither add nor remove energy from a closed system, so the energy within it is conserved.

∙ 13y agoYes and no. Energy is conserved in the universe, always. However, if you have a problem with an open system you cannot use conservation of energy to solve it. You can use conservation of momentum, however, if it is applicable to the content of the problem.

∙ 13y agoThat means that the total energy remains constant. One type of energy might be converted to another type of energy, but no energy gets lost or created in the process.

The type of circulatory system in which the blood remains within the vessels is?
Closed- AmandaLG
Do rabbits have an open or closed circulatory system?
closed. Open circulatory systems are common in athropods, such as scorpions and insects, but not of mammals. They are when the body lacks blood vessels but has blood throughout the entire cavity of the body. Mammals have closed circulatory systems, as they contain blood vessels.
What is a open and closed circulatory system?
In a closed circulatory system, the circulatory fluid remains within blood vessels at all points in the circulatory system. In an open circulatory system, the circulating fluid enters a sinus at least at one point in the circulating system and thus comes in direct contact with the tissues.
A closed sac within a synovial membrane lining is called a?
bursa
Why is the human cardiovascular system consider closed?
Because if it wasn't you would have massive internal bleeding, be extremely cold and die within seconds, imagine your circulatory system is like central heating which is also a closed system ,what would happen to the water if it didn't go round and round? You would have very soggy floors and a cold house - same thing with your body :D
What does it mean to say energy is conserved within a system?
When an object is accelerated along a distance that requires energy. If the object is then slowed to a stop by a breaking system that gets back that energy then the energy is said to be conserved
How can conservation energy be used?
Conservation energy is energy that is conserved. The energy remains conserved within the unit whether it has been turned off or closed. When the device is turned back on the energy that was contained is released and therefor uses less energy.
Within which type of system is neither the total mass nor the total energy conserved?
That would be impossible as mass and energy are related.
How is the energy of rolling object differ from the energy of the same object at rest?
When the object is rolling it has kinetic energy or KE and when the object is at rest it has potential energy or U. In this case both are mechanical energies and mechanical energy is conserved within a system meaning it is only transferred not gained or lost.
Why closed system is termed as control mass?
A closed system is termed as a control mass because it does not exchange mass with its surroundings. This means that no mass enters or leaves the system, and therefore the total mass within the system remains constant. This allows for the analysis of the system's energy changes and thermodynamic processes in isolation, making it a control mass for studying energy transfers and conservation.
When the momentum within a system is the same before and after an event you say that what?
You say that momentum is conserved. This is always the case, if the system has no interaction with anything outside the system.
What does thermal energy refer to?
The kinetic energy within a system
The type of circulatory system in which the blood remains within the vessels is?
Closed- AmandaLG
Ones internal thermal energy?
Internal energy is defined as the sum of the randomly distributed potential energies plus the sum of the randomly distributed kinetic energies within a closed system.
What is the thermal energy of system?
The total kinetic energy within a system
What is Thermal energy of a system?
The total kinetic energy within a system
Why is the frog's circulatory system called a closed system?
It is called closed because all the plasma and its contents are contained within the vessels.
