When 100 J of heat is added to a system that performs 60 J of work the thermal energy change of the system is?
If 60 Joules of mechanical energy is transformed to thermal energy without losses, the heat produced will be the equivalent of 60 Joules which is 14.3 calories (4.2 Joules per calorie)
When a muscle contracts it performs work It does this by?
When a muscle contracts, it performs work. It does this byA)converting chemical energy to mechanical energy.B)converting mechanical energy into heat energy.C)converting mass into energy.D)creating energy.
What is the heat engine?
A heat engine is a system that converts heat to usable energy, particularly mechanical energy, which can then be used to do mechanical work
What is the difference between heat engine and heat pump?
Heat Engine is the system that converts the Heat energy into mechanical work while Heat pump converts the work into heat
What directly causes mechanical motion?
The application of HEAT, in any of it's Forms; heat to overcome Inertia.
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 are examples for mechanical heat energy?
As far as I know, there is no such thing as "mechanical heat energy"; there is mechanical energy, and there is heat energy.
What happens when heat is added to a system?
When heat is added to a system, the temperature increases, unless there is a phase change taking place. In that case, temperature remains the same, and the only observable difference is the phase change.
What is the relationship between heat added to a system and the internal energy and external work done by the system-?
When heat is added to or is absorbed by a system, its internal energy increases. The amount of external work a system can do essentially refers to the amount of energy it can transfer to something else. So when internal energy increases, so does the external work done by the system.
Heat exchange in chemical reactions is due to a change in what?
Enthalpy-The heat added to or loss by a system at constant pressure
According to Le chatelier's principle what happens if heat is added to a system?
The reaction shifts to remove the heat APEX
According to Le Chatelier principle what happens if heat is added to a system?
The reaction shifts to remove the heat APEX
