What else can I help you with?
What comparison of work the machine does with energy it uses to do the work?
The work done by a machine is directly related to the amount of energy it uses. Machines convert the input energy into work output, with the efficiency of this conversion determined by factors such as friction, heat losses, and mechanical losses within the machine. The more efficient the machine, the more work can be accomplished with the same amount of energy.
How does heat engines work?
A heat engine uses energy to work and exhaust heat that can't be used. Thermodynamics constrain the operation of a heat law and apply the conservation of energy to the system while limiting the possible efficiency of the machine to determine the direction of flow.
How does oil heat up your homes?
oil does not heat up homes is use for a machine that uses the oil to work like gas from cars but the oil used for heating machines is not the ones car uses it made from it and that's how it works
What are the uses of a simple machine?
Doing work.
Why does your heat only work when your car is moving?
The heat will also work when the car is turned on, but not moving. It uses heat from the engine.
What are the uses of coldness and heat in machines?
Some machines have to be kept cold to work properly. When a machine gets to hot or overheated it breakes down. So as a reacap when a machine is cold it works great but to hot it breaks down.
Electrical energy to heat energy what machine use this?
an elecric heater uses the conversion of electrical energy into heat energy.
What type of device is in the car engine?
A heat engine that uses heat to do work
What type of device is a refrigerator?
a heat pump that uses work to move heat
When using a real machine to do work input work will always be?
When using a real machine to do work, input work will always be greater than the output work due to the presence of factors such as friction, heat loss, and inefficiencies in the machine. This difference in work is known as the machine's efficiency, which is a measure of how well the machine converts input work into useful output work.
The output work of a machine compared to the input work is?
The output work of a machine is typically less than the input work, due to factors such as friction, heat loss, and other inefficiencies in the machine's operation. This difference between input and output work is known as the efficiency of the machine.
What is the heat engine?
a machine that transforms heat into machanical energy, or work
