What is the change in the internal energy of a system that does 400 joules of work and absorbs 700 joules of heat?
400 joules.
What the internal energy of a system that does 5000 joules of work and absorbs 20000 joules of heat?
15,000 joules... APEX
How much heat is generated by 1700 joules of work?
If all 1700 Joules of work get converted into heat, then, of course, you get 1700 Joules of heat.
A certain system absorbs 350 joules of heat and has 230 joules of work done on it?
A certain system absorbs 350joules of heart and has 230joules of work done on it. What is the value of Delta?
When 100 J of heat is added to a system that performs 60 J of work the thermal energy change of the system is?
If 60 Joules of mechanical energy is transformed to thermal energy without losses, the heat produced will be the equivalent of 60 Joules which is 14.3 calories (4.2 Joules per calorie)
What is the change in internal energy if 20 joules of heat is released from a system and the system does 50 joules of work on the surroundings?
-70 Joules
What is the change in the internal energy of a system that does 400 joules of work and absorbs 700 joules of heat?
400 joules.
What the internal energy of a system that does 5000 joules of work and absorbs 20000 joules of heat?
15,000 joules... APEX
During the change in energy in a closed system during a specific interval of time was 15 Joules and 10 Joules of heat was radiated out of the system during the same period of time what is work?
work is -25 joules
How much heat is generated by 1700 joules of work?
If all 1700 Joules of work get converted into heat, then, of course, you get 1700 Joules of heat.
A certain system absorbs 350 joules of heat and has 230 joules of work done on it?
A certain system absorbs 350joules of heart and has 230joules of work done on it. What is the value of Delta?
When 100 J of heat is added to a system that performs 60 J of work the thermal energy change of the system is?
If 60 Joules of mechanical energy is transformed to thermal energy without losses, the heat produced will be the equivalent of 60 Joules which is 14.3 calories (4.2 Joules per calorie)
How many joules are in a Calorie or science calorie?
In 1 joule there is 0.238902957619 calories of heat. A joule is the measurement of work, energy or the amount of heat in the International System of Units.
What is the efficiency of a pulley system when its work out equals 100 joules and its work in equals 150 joules?
If the input energy is 210 joules and the efficiency of the system is 30%,then the output energy is30% of 210 = (0.3 x 210) = 63 joules.
What is the heat loss of an engine that has an input of heat energy of 10750 joules and does 2420 joules of work?
2420 / 10750 = .225 or a Coefficient of Performance (COP) = 22.5
What is the change in the internal energy of a system that does 5000 joules of work and absorbs 20000 joules of heat?
1,000 J
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.
