No, it is net amount of energy in a close system is constant. Energy can change form from thermal to kinetic to electrical and so on. It is only the net amount of energy that is conserved in the close system.

Can sound power a house with sound?
No. See the first law of thermodynamics, which states that the change in the internal energy of a closed thermodynamic system is equal to the sum of the amount of heat energy supplied to or removed from the system and the work done on or by the system or we can say " In an isolated system the heat is constant".
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 basic things of thermodynamics?
The First Law of Thermodynamics is the conservation of energy. You can't create energy, nor destroy it; the total amount of energy in a closed system remains constant.The First Law of Thermodynamics is the conservation of energy.

What happens to a gas temperature at a given pressure?
In a closed system with constant pressure and no input or output of heat, the gas temperature will remain constant. In that same system, if the pressure is increased, then the gas temperature will also increase. If pressure is decreased, then the gas temperature will decrease.
When energy is transformed is some lost or gained?
there is an increase in entropy in the universe.
What is the amount of heat to change liquid into solid at constant temperature?
To change a liquid into solid at constant temperature, an amount of heat is released equal to the latent heat of that liquid. For water it is about 80 calories per gram.
Is it true that the entropy of a system decreases over time?
false
The heat content of a system at constant pressure?
Enthalpy
What is the amount of heat energy in the earth's surface referredd to?
Solar Constant
What is different between adiabatic system and isothermal system?
An isothremal process is one in which the temperature is constant. heat can be gained or lost in order to maintain a constant tempereature. An adiabatic process is one in which there is no heat exchange between a system and its surroundings. It does not matter whether the temperature of the system is constant or not.
What is a closed system in thermodynamics?
A thermodynamically closed system is one where no mass enters or leaves the system. That does not preclude the possibility of heat or work entering or leaving the system.
The amount of heat necessary to change a liquid to a solid at constant temperature?
None - heat is evolved, not required.
