Is temperature a work done?
No, HEAT is work done!
How much work is done by the heat engine if it takes in 2000J of heat and rejects 1500J of heat?
Work done=Heat in-Heat out 2000-1500=500J
The amount of work done by heat engine equals the amount of what?
the amout of work done on the engine
How do you find relationship between work and heat practically?
if only heat change is the only change then energy difference is the amount of work done.
How is Physics applied at home?
Physics is the study of the nature and properties of matter and energy. At home, it is applied in how much energy is consumed by the appliances, how much heat is applied when cooking and the work done in household chores.
What is the definition of thermal efficiency?
the efficiency of a heat engine measured by the ratio of the work done by it to the heat supplied to it.
Energy is what when work is done?
Usually it dissipates into heat released into the surroundings.
What is thermal efficiency?
Thermal efficiency is the efficiency of a heat engine measured by the ratio of the work done by it to the heat supplied to it.
What is nature of contract?
Terms and conditions agreed upon by owner and contractor for work to be done.
Why can't the work done by a machine be greater than the work done on the machine?
Because work is the amount of energy transferred into or out of a system, not counting energy transferred by heat conduction.
What happnes to energy when work is done?
Usually it dissipates into heat released into the surroundings.
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.
