How the internal energy of air can be increased by?
The internal energy of air can be increased by adding heat to it. When heat is added to air, the energy of the air molecules increases, causing them to move faster and have higher kinetic energy. This increase in kinetic energy results in an increase in the internal energy of the air.
The addition of heat energy to a system always causes the temperature of that system to increase.?
Yes. Adding heat will increase temperature.
If work is don adiabatically on a system will the internal energy increase or decrease?
If work is done adiabatically on a system, the internal energy will increase. This is because adiabatic processes do not involve the exchange of heat with the surroundings, so any work done on the system will directly contribute to an increase in its internal energy.
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
What happens to the internal energy of a system when work is done on it?
If the internal energy of the system increases the temperature will increase.
Is the heat supplied to a system always equal to the increase in its internal energywhat thermodynamic variable is defined by zeroth law and first law of thermodynamic?
The heat supplied to a system can increase its internal energy if no work is extracted from the system. If any work is done by the system, then the increase in internal energy will be less than the heat supplied to the system. The thermodynamic variable defined by the zeroeth law is Temperature.
How does adding energy to matter affect the energy of its particles?
The energy will increase and the particles will speed up.
What happens to internal energy when mechanical work is done?
Increase.
what is the most energy efficient way to evaporate water?
Adding thermal energy increase the evaporation.
When mechanical work is done on a system there is an increase in what?
both temperature and internal energy
Why does the internal energy of a gas increase when it is compressed with no heat transfer between it and surroundings without making reference to the first law of thermodynamics?
Try this for a short, simple, beautiful, and correct answer: The internal energy increases because in order to compress the gas, you had to squeeze it, i.e. you had to apply force to the boundary of the container and force the gas to become smaller. Since you applied force and moved it through a distance, work (energy) was done. That energy was added to the internal energy of the gas. Since the gas isn't in motion ... at least macroscopically ... the increase in internal energy shows up as an increase in temperature.
What happened to the kinetic energy of the particles in a sample of gas as the temperature of the sample increase?
The average Kinetic energy of the atoms in the sample will increase as the sample is heated.
