How does the thermal energy of a system change when work is done on The system?

Usually the "thermal energy" will increase since work ON the system adds energy. Thermal energy is really not the best term though. A much better term in thermodynamics would be ENTHALPY.

Can solar energy be changed into thermal energy without any work being done?
YesIt is true that solar energy can be changed into thermal energy without any work being done. The solar energy is thermal energy from the sun.
When a system does work and no heat is added to the system its temperature?
remains constant From Rafaelrz. When a simple closed system does work and no heat is added, the temperature of the system will drop. This is because the work is done at the expense of his internal energy, which is thermal energy.
What is The first law of Themodynamics?
* First law of thermodynamics, about the conservation of energy: : :: The change in the internal energy of a closed thermodynamic system is equal to the sum of the amount of heat energy supplied to the system and the work done on the system. --from Wikipedia
How work is related to powerand energy?
Power is the rate at which work is done. That isPower = Work/Time.Work done is also the change in the total mechanical energy of a system between its initial and final state.Work = Final Energy - Initial Energy
Can thermal energy be used to do work?
yes thermal energy be uses to do work exp. if we have a gas enclosed in a cyllinder with frictiion less piston,when we provide a themal energy then electrons aquire sufficient themal velocity and moving zig-zag path. so they change the volume of the gas and change the position of that piston. so the work is done= F.d, here angle between force and distance is zero.
Can work done on a system decrease its thermal energy?
Yes. As an example: if you define a refrigerator as your system, the work done on the system causes heat to be expelled from the system to the surroundings. The net heat expelled will be equal to the work input plus the decrease in its thermal energy.
Can solar energy be changed into thermal energy without any work being done?
YesIt is true that solar energy can be changed into thermal energy without any work being done. The solar energy is thermal energy from the sun.

Which law states that thermal energy increases depend on the work done and the heat added?
Conservation of energy.

A measure of heat energy?
A measure of heat energy can be done easily using a thermometer. This will measure the amount of thermal energy transferred.
A energy is?
Energy is the potential to do some work. If there is work done on a system, this work done is stored as potential energy of the system. If the system in motion, it should have kinetic energy. Hence total energy of the system PE+KE
What is the difference between thermal and heat energy?
Thermal energy is a quantity that can be measured in BTU or Calories. Heat transfer is just a method of transferring that energy from one place to another, or one part of a machine to another part. Heat transfer does not create any energy in itself.
Can thermal energy be used to do work?
yes thermal energy be uses to do work exp. if we have a gas enclosed in a cyllinder with frictiion less piston,when we provide a themal energy then electrons aquire sufficient themal velocity and moving zig-zag path. so they change the volume of the gas and change the position of that piston. so the work is done= F.d, here angle between force and distance is zero.
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.
How are thermal energy an temperature related?
Macroscopically, the thermal energy of a system at a given temperature is related proportionally to its heat capacity. However, since the heat capacity differs according to whether or not constant volume or constant pressure is specified, or phase changes permitted, the heat capacity cannot be used define thermal energy unless it is done in such a way as to insure that only heat gain or loss (not work) make any changes in the internal energy of the system. Usually, this means constant volume heat capacity so that no work is done, and also the heat capacity of a system for such purposes must not include heat absorbed by any chemical reaction or process. <a href="http://tutorearth.com">Tutor Earth</a>
