If a machine is never 100% efficient transforming energy into work because part of the energy is converted into heat, does it mean an electric heater is 100% efficient? @[email protected]

Yeah, but than, does it really makes a sound?
At the expense of ruining the joke, yes it does. Anyone inside the room would be able to hear the sound.
And if no one is in the room to hear if there is a sound or not, you might want to turn the heater off to conserve energy.
Oh I didn’t think of it!
