What else can I help you with?
Which one of the following conditions would always result in an increase in the internal energy of a system?
the system gains heat and does work on the surroundings
The amount of power derived from a device or system is its?
That amount is always less than the energy you put into the system. Divide the amount of useful energy you get from a system by the amount of energy you put into it, and you find the system's 'efficiency'.
What best describes kinetic energy?
Energy is the indirectly observed quantity that has power to cause a change in a system. We do not observe energy directly - we only observe the effects that it has on systems as they change. According to the first law of thermodynamics, the energy of an isolated system (one where no mass or energy are entering or leaving) must remain constant. Energy never disappears it just forms into another type of energy
Which of the following is correct unit for speed in MKS system?
The correct unit for speed in MKS system is 'm'.
Energy is transferred from insects to fish in this system by?
energy is tranferred from insects to fish in this system by?
What happens to energy in closed system?
In a closed system, energy can neither enter nor exit. It can only be transferred or transformed within the system. This means that the total amount of energy in the system remains constant, following the principle of conservation of energy.
What happens when energy is transferred from system to system?
heyye
What happens when energy is transfered from system to system?
heyye
What term describes the average kinetic energy of a system?
Temperature.
What happens to kinetic energy and potential energy in a closed system?
In a closed system, the total energy (kinetic + potential) remains constant, following the principle of conservation of energy. As kinetic energy increases, potential energy decreases, and vice versa. This continuous exchange between kinetic and potential energy allows the system to maintain a constant total energy.
When thermal energy is added to system what happens to the overall energy in that system?
When thermal energy is added to a system, the overall energy in the system increases. This is because the thermal energy contributes to the internal energy of the system, raising the total energy content.
What best describes the solution to the system of equations below?
Which of the following best describes the solution to the system of equations below?3x + 6y = 10 9x + 18y = 30
What happens to the total energy in an isolated system?
In an isolated system, the total energy remains constant and does not change.
What best describes energy transfer in a closed system?
In a closed system, energy can be transferred between different components within the system but does not enter or leave the system. This means the total energy within the system remains constant, in accordance with the principle of conservation of energy.
What happens when energy is absorbed by a system?
When energy is absorbed by a system, it is taken in and used to increase the system's internal energy, which can lead to changes in temperature, state, or other properties of the system.
When a system does work what happens to its internal energy?
It decreases.
What happens to matter and energy in closed system?
In a closed system, neither the energy or matter changes. (Study Island)
