Does the machine transfer energy?
When the process energy is transferred, it moves from one object of energy to another. Machines do transfer energy through the process of mechanical work.
In a machine is work output is less than work input because some energy is converted into thermal energy?
In a machine, work output is less than work input due to energy losses from friction, air resistance, and other inefficiencies. Some of the input energy is converted into thermal energy, leading to a decrease in the useful work output of the machine.
Do machines use power to perform work in a more energy efficient manner?
Yes, machines can be designed to perform work in a more energy efficient manner by optimizing their design and reducing energy losses during operation. This can help save energy and lower operating costs.
How is energy used in machines?
Energy is used in machines to perform work, such as moving objects, generating heat, or producing electricity. Machines convert different forms of energy, such as electrical, mechanical, or thermal energy, to accomplish various tasks efficiently. The amount of energy input to a machine should ideally match the output needed to complete the desired function.
How does the thermal energy of a system change when work is done on The system?
Usually the "thermal energy" will increase since work ON the system adds energy. Thermal energy is really not the best term though. A much better term in thermodynamics would be ENTHALPY.

Can thermal energy be made to do useful work?
Thermal energy is what is practically the ONLY source of energy for any work. Thermal energy cools, heats, runs motors, etc.

What is the study of relationships between heat work and thermal energy?
Thermodynamics is the study of the relationship between thermal energy and heat and work.
In a machine work output is less than work input because some energy is converted into thermal energy True or false?
True. In a machine, not all of the input work is converted into useful output work. Some of the input work is lost as thermal energy due to friction, inefficiencies, and other factors. This is why the output work is always less than the input work.
What extra heat given off by machines as they work?
It's not exactly "extra". It's a part of the energy that you put INTO the machine in order to get the work done. Machines always do LESS work than the energy you put into them, and the rest turns into heat. You always lose some. That's just the way things work.
What are machines that run off of thermal energy?
Geothermal power plants and Stirling engines are examples of machines that operate using thermal energy. Geothermal power plants harness heat from beneath the Earth's surface to generate electricity, while Stirling engines use temperature differentials to drive a piston and produce mechanical work.
Can work done on a system decrease its thermal energy?
Yes. As an example: if you define a refrigerator as your system, the work done on the system causes heat to be expelled from the system to the surroundings. The net heat expelled will be equal to the work input plus the decrease in its thermal energy.
