What happens to the internal energy of a system when work is done on it?
When work is done on a system, its internal energy increases. This is because the work done transfers energy to the system, raising the energy of its particles and increasing their kinetic and potential energies.
Is it possible to add energy to a system without increasing the temperature of that system?
Yes, it is possible to add energy to a system without increasing its temperature by converting the added energy into a different form, such as potential energy or kinetic energy. The internal energy of a system can change without a temperature increase if the energy is used for processes like phase changes or chemical reactions.
How to increase a Thermal efficiency of rankine cycle?
To increase the thermal efficiency of a Rankine cycle, you can: Increase the temperature of the heat source entering the boiler. Lower the temperature of the heat sink exiting the condenser. Improve the insulation of the system to reduce heat losses. Enhance the performance of the turbine and pump by reducing internal losses.
What is the meaning of internal heat generation?
Internal heat generation refers to the production of heat within a system or object as a result of various processes such as chemical reactions, friction, or electrical resistance. This phenomenon can lead to an increase in temperature within the system, impacting its overall thermal properties and performance.
What happens when an object's temperature is rising?
When an object's temperature is rising, it means that the average kinetic energy of the particles within the object is increasing. This leads to an increase in the object's internal energy and can result in physical changes like expansion, changes in state (e.g. melting), or chemical changes.
Temperature and pressure increase with depth inside Earth - True or False?
True. As you go deeper into the Earth, both temperature and pressure increase due to the weight of the overlying material and the Earth's internal heat.
What happens to the internal energy of a system when work is done on it?
When work is done on a system, its internal energy increases. This is because the work done transfers energy to the system, raising the energy of its particles and increasing their kinetic and potential energies.
How does the internal structure increase the efficiency of the mitochondria?
By increasing surface area. So more can bind

When mechanical work is done on a system there is an increase in what?
When mechanical work is done on a system, there is an increase in the system's internal energy. This increase in internal energy is due to the transfer of energy from the mechanical work applied to the system.
What causes NO2 in internal combustion engines?
lean mixture..results to increase NO2,, increasing the fuel will reduce NO2 but increase carbon monoxide, so the EGR is developed to reduce NO2 without increasing the fuel in turn increasing the CO.
What causes the internal resistance of a dry cell to increase as time passes by?
The internal resistance of a dry cell can increase over time due to chemical reactions taking place within the cell that can degrade the electrodes and electrolyte. This can lead to the build-up of resistance within the cell, affecting its overall performance and reducing its ability to deliver current effectively. Additionally, factors such as cell aging and discharge cycles can contribute to the increase in internal resistance over time.

Does eating mango increase internal body temperature?
No, eating mango does not directly increase internal body temperature. However, the digestion process may generate some heat as energy is expended to break down and absorb the nutrients, but this increase in body temperature is minimal and typically temporary.
By what means can the internal energy of a system increase?
there are a number of ways: you could put that system into direct thermal contact with another system of a higher temperature, which would result in a conduction of heat energy from the higher energy system to the lower one. Or you could fire radiation at the system which the system absorbs and thus its internal energy is raised. I think you might increase the energy if you decrease the volume under pressure, because the temperature will increase and you will have done work on the system, hence increasing it internal energy. Like wise, if you spray a deodorant can, it comes out cold, because the compressed gas has done work on the atmosphere, and used up internal energy, hence it feels cold.
