What would cause the calorimeter efficiency to be less than 100 percent?

why is the efficiency of a calorimeter less than 100%


What is the efficiency is the output work is 12000 and the input work is 15000?

Efficiency as a percent is output/input * 100%12000/15000 * 100% = 80% efficiency which makes sense, because it takes more work (input) than it give out (output). So the efficiency should be less than 100%.


Does a refrigerator have 100 percent efficiency?

nothing has 100% efficiency.


The efficiency of an actual machine is always less than what percent?

It is always less than 100% Theoretical machines can have efficiencies of 100% but in practice there is always some energy loss Efficiencies of more than 100% are not allowed by the laws of thermodynamics!


Can a machine's efficiency can be greater than 100 percent?

nope, efficiency o fa machine cannot be greater than 100%...theoretically it shows sometime that efficiency of a machine can be 100%, but practically it cannot be possible as there is some loss of energy is always involved in different ways.


What is the formula for calculating efficiency?

General formula for calculating efficiency is given by Efficiency = (output / input) * 100 It is denoted by greek letter Eta Efficiency cannot be more than 100%.


Why is efficiency of machine not 100?

If there would be a machine with an efficiency of 100 you would have perpetual motion. Some energy must be lost to friction, heat, gravitational pull.Boss if you have efficiency more than 100 % that means your output is more than input, so from where the excess energy you get ...?


Can a car have a 100 percent efficiency?

No. Nothing mechanical can ever have a 100% efficiency by any physical evaluation.


Can a machine be more than 100 percent efficient?

100% efficiency would mean that the machine is able to transform energy from one form into another without any loss of energy from the system in the process. For it to have greater than 100% efficiency, it would have to somehow generate additional energy, not contained in the system, in the process, and this is not possible.


Is a machine physically possible that has an efficiency greater than 100 percent?

Not if the laws of physics - specifically thermodynamics - are correct.
