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
What is the definition to energy input?
The definition to energy input is something in a system or expended in its operation to achieve output or a result.
What is meant by internal energy of the system?
Depending what you relate it to. In an electronic system it would relate to the amount of watts consumed or supplied; whereas, an organic system would be the magnitude of glucose (or equivalent).
What happens to the heat energy which is supplied to the solid once it has started melting?
During the phase change of a solid to a liquid (melting), all of the energy goes into breaking the intermolecular bonds holding the molecules of the solid together, and none of the energy goes into changing the temperature. Thus, during this particular phase of melting, the temperature of the system does NOT change.
A system delivers 225 J of heat to the surroundings while delivering 645 J of work Calculate the change in the internal energy ΔE of the system?
∆E (internal energy) = q (heat flow) + w (work) The question says that heat is delivered to the surroundings (therefore lost by the system so (-)). Also, It says in the same statement work is being delivered, so work is also negative. ∆E = -225J + (-645J) = -870
What body system delivers energy to the muscles?
Energy is not delivered by any body system.
What is the electrical voltage are supplied by the power supply on your system?
The electric voltage are energy to my system.
Is the heat supplied to a system always equal to the increase in its internal energywhat thermodynamic variable is defined by zeroth law and first law of thermodynamic?
The heat supplied to a system can increase its internal energy if no work is extracted from the system. If any work is done by the system, then the increase in internal energy will be less than the heat supplied to the system. The thermodynamic variable defined by the zeroeth law is Temperature.

Why is necessary to control over speed in a motor?
over speed control is recommended for all prime mover driven generator to prevent over frequency operation of load connected to a system supplied by the generator and also to prevent possible over frequency operation of the generator itself from Ac 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".
How were the Roman cities supplied with water?
The Romans had a complex system of aqueducts that ran throughout the entire empire that delivered clean water to all the cities.
How is water supplied to your homes?
It is supplied, under pressure, through a system of underground pipes.
The body is supplied with oxygen by the?
respiratory system
