Because they output (send out) heat.
To calculate the output of a gas fire, you need to know the heat input rating of the gas fire in British thermal units per hour (BTU/hr) or kilowatts (kW). The heat output is typically a percentage of the heat input, commonly around 70-90%. You can calculate the heat output by multiplying the heat input by the efficiency percentage (e.g. heat output = heat input x efficiency percentage).
It must use a function with a "return" statement. Or you could output via console. (.NET CODE(C#)) Console.WriteLine("Output.");
The difference between output and outcome is that , output is the product or service that comes out of a process and outcome is the net result of that output to the organization.

The efficiency of the carnot engine - or any engine for that matter - is given by the quocient between the desired effect and what you payed for it, that is, the quocient between the net work output and the heat added to the system.
Physical activity increases human heat output. When we exercise or engage in physical activity, our muscles generate heat as they work, causing our bodies to produce more heat. This increase in heat output helps to regulate our body temperature and keep us from overheating during physical exertion.
no even it will increase the out put heat
The output energy of a fridge is typically in the form of heat released into the surrounding environment. This heat is removed from the interior of the fridge to keep the contents cool. The energy output is mainly in the form of thermal energy.
A flashlight outputs light and heat.
A flashlight outputs light and heat.
The formula for calculating the efficiency of a heat pump is the ratio of the heat output to the energy input, expressed as a percentage. It can be calculated using the formula: Efficiency (Heat Output / Energy Input) x 100.
