Water is heated by gas in a boiler. The water is put in a tank. For every 111J of energy released by the gas 100j of energy is taken in by the boiler. What is the percentage efficiency off the boiler?

You are supposed to divide output power / input power. Or in this case, output energy / input energy.

What is the percentage of energy used to do work called?
The term EFFICIENCY is defined as useful work, divided by total energy expenditure.
Does a high-efficiency machine degrade a relatively high or low percentage of energy to thermal energy?
It degrades a low percentage.
Percentage of energy that is used by a device to perform work is called?
That is called the "efficiency" of the device.
What compares the energy output of a system with its energy input?
Is it's Energy Efficiency.
What happens to wasted energy from a boiler?
the energy wasted by the system(boiler) is gained by the surrounding atmosphere
What percentage of the input energy does a gas boiler waste?
69%

Percentage of energy that is used by a device to work?
efficiency(:
Why does a high-efficiency machine is more desirable than low-efficiency machine?
High efficiency means that a large percentage of the energy used is converted to something useful (the desired output of the machine), and a low percentage is wasted.High efficiency means that a large percentage of the energy used is converted to something useful (the desired output of the machine), and a low percentage is wasted.High efficiency means that a large percentage of the energy used is converted to something useful (the desired output of the machine), and a low percentage is wasted.High efficiency means that a large percentage of the energy used is converted to something useful (the desired output of the machine), and a low percentage is wasted.
What does efficiency mean in science?
The Efficiency of a system is the ratio (Input Energy / Output Energy). The fraction is usually expressed as a percentage.
What is the formula to find mechanical efficiency?
Mechanical efficiency = (output energy)/(input energy) . It's typically stated as a percentage.
Can you get more energy out of fuels if you increase the percentage of energy used for work?
The percentage of energy converted into useful work is called the EFFICIENCY.
Percentage of energy that is used by a device to perform work?
Efficiency.
What is the The percentage of energy that is used to preform work?
That is called the "efficiency".
What is a percentage of energy that is used by a device to perform work?
The answer is efficiency.
Does a high-efficiency machine degrade a relatively high or low percentage of energy to thermal energy?
It degrades a low percentage.
What is the ratio of the energy a machine delivers to the energy supplied to it?
efficiencyThe ratio of useful energy to total input energy is called efficiency. It refers to the percentage of the work input that is converted to work output.
