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.

How does the temperature of gas change when it is compressed if the process is adiabatic?
In an adiabatic process, the temperature is increased when it is compressed. There is an increase in internal kinetic energy, and because temperature is related to kinetic energy, it is also increased.
The source of thermal energy in an internal combustion engine?
The source of thermal energy in an internal combustion engine is from a combination of pressure (the piston compressing the air/fuel mixture), ignition of air/fuel mixture by spark plug (largest contributor), and friction of moving parts inside the engine.
In an air compressor the compression takes place at a constant internal energy and 50 kj of heat are rejected to the cooling water for every kilogram of air Calculate the work input for the compre?
Q1 In an air compressor the compression takes place at a constant internal energy and 50Kj of heat are rejected to the cooling water for every Kilogram of air. Calculate the work input for the compression stroke per kilogram of air?
How can the energy of the molecules of a solute and solvent be increased?
The energy of molecules in a solute and solvent can be increased by adding outside energy, say, heat, for instance.
Is the total energy of the molecules in a material.?
internal energy
If speed of fan is increased is energy consumption increases or decreases?
Energy consumption increases due to the increased air mass flow brought about by higher fan speed.
When 430 J of work is done on a system it lost 120 J energy as heat Calculate the value of internal energy change for this process?
The first law of thermodynamics requires that energy input must equal energy output plus energy accumulation. In this case that translates to; 430 J = 120 J + (internal energy change) so Internal energy change = 430 J - 120 J = +310 J (the internal energy increased by 310 Joules)

What is the Principle of Loudspeaker?
Electric energy cause a membrane to move by turning into mechanical energy. The movement of the membrane causes the air pressure to besequentially increased and rarefied. This "train" of increased and rearefied air pressure propagates into the room, and if it strikes our ear drums we perceive it as sound.
What is internal energy of an object?
the energy which absorved in the object is called internal energy
How does a ball get pumped up by the sun if it is left outside?
If a soccer ball that is otherwise able to hold its pressure fairly well is heated by the sun, it will, indeed, increase its pressure. Thermal energy is transferred to the air (which is already compressed) inside the ball, and it causes the gas atoms and molecules to increase their thermal energy. This thermal energy causes increased vibration and increased "bouncing around" among the heated gas particles. The increased kinetic energy added to the air by the heat of the sun has increased the pressure in the ball.
Why do you take in more air when running?
Running equals increased energy production, which requires more oxygen, which requires more air per minute.
What happens to the energy level as something evaporates?
When something evaporates, the energy level increases. The particles gain enough energy and begin to spread apart, and into the air. With the increased energy level, it gives the liquid, or even the solid (sublimation), enough energy to vaporize (or evaporate) into thin air.

The source of thermal energy in an internal combustion engine?
The source of thermal energy in an internal combustion engine is from a combination of pressure (the piston compressing the air/fuel mixture), ignition of air/fuel mixture by spark plug (largest contributor), and friction of moving parts inside the engine.
What is internal energy?
Internal energy is defined as energy associated with the random, disordered motion of the molecules.
