Internal energy is an extensive state function. That means it depends on how much of a substance you have but if you fix the composition, pressure, temperature, volume, and (in the case of a system at a phase equlibrium point, like water at the freezing point) the phase of a system, the specific internal energy will be constant. If you take a closed system and change the volume of it, you will be doing work (or allowing the system to do work) and the internal energy can change - so - yes - internal energy of a system depends upon volume. Also, if you fix the composition, temperature, pressure, and phase of a homogeneous mass but change the volume, you will increase the amount of mass you included in the system, thus changing the total internal energy (because it is, after all, an extensive function).
Thermodynamic properties are specific volume, density, pressure, and temperature. Other properties are constant pressure, constant volume specific heats, Gibbs free energy, specific internal energy and enthalpy, and entropy.
It is change in internal energy. If the volume of the system remains unchanged (isochoric process)then the heat given to the system is entirely utilized to increase the internal energy of that system. It is to be noted that no pressure-voulme work is done in such processes.
As the gs flow from high pressure to low pressur using the porus plug the temperature of the gas increases as the pressure of the gas decreases. As we know in all this process the enthalpy is constant . So, to stay it constant the internal energy increases which lead to increase in temperature of the gas. Formula h=u+pv h--- enthalpy u-- internal energy p--pressure v---volume

For a gas it is the value of u+pv where u=internal energy p=pressure v=volume
The volume of gas depends on the temperature, pressure, and number of gas particles present. These factors affect the amount of space the gas particles occupy.

The answer will depend on what characteristic of the thumb you wish to measure: length, width, mass, volume, resistance to pressure, etc.The answer will depend on what characteristic of the thumb you wish to measure: length, width, mass, volume, resistance to pressure, etc.The answer will depend on what characteristic of the thumb you wish to measure: length, width, mass, volume, resistance to pressure, etc.The answer will depend on what characteristic of the thumb you wish to measure: length, width, mass, volume, resistance to pressure, etc.
The internal pressure of the lungs is controlled by the diaphragm and the muscles of the thorax (chest). Inhalation is caused by increasing the volume (which lowers the internal pressure) while decreasing the volume (increases the internal pressure) leads to exhalation, similar to the way a bellows works. The elastic qualities of the lung also help the process of exhalation.
Volume and temperature
Pressure is a force applied over an area. Volumes have internal pressures.
No. The volume remains the same unless the material from which it is made is flexible and elastic
Since we are talking abut heating and cooling - we define those both as changing the temperature so that is one characteristic. Other characteristics depend on how the heating and cooling occur. If the pressure remains the same, air will expand on heating and contract on cooling. If the volume is held constant, the pressure will increase with heating and decrease with cooling. The internal energy depends on what you do with pressure, work and heat. You can actually get a warmer gas with less internal energy and a cooler gas with more internal energy.
