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.
100 joules of heat plus to system of 60 joules of work?
internal energy change in words is the difference between the added energy and the original energy 100 - 60 = 40J
What the internal energy of a system that does 5000 joules of work and absorbs 20000 joules of heat?
15,000 joules... APEX
If 800 joules of heat are added to a gas in an isochoric process what is the change in its internal energy?
The change would be 100 joules, because an isochoric system can not perform the work.
When 430 J of work is done on a system it lost 120 J energy as heat Calculate the value of internal energy change for this process?
The first law of thermodynamics requires that energy input must equal energy output plus energy accumulation. In this case that translates to; 430 J = 120 J + (internal energy change) so Internal energy change = 430 J - 120 J = +310 J (the internal energy increased by 310 Joules)
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.

The first law of thermodynamics requires that energy input must equal energy output plus energy accumulation. In this case that translates to; 430 J = 120 J + (internal energy change) so Internal energy change = 430 J - 120 J = +310 J (the internal energy increased by 310 Joules)
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
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
What is the definition for energy change?
Energy change refers to the difference in the amount of energy of a system before and after a process. It can be in the form of heat, work, or a combination of both. Energy change is typically quantified in units such as joules or calories.
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)
A system absorbs 640J heat and does work of 260J the change in internal energy of the system will be?
the system has been given internal energy of 640j and the work system does on surroundings is 260j. therefore by first law of thermodynamics the internal energy of system increases by (640-260=380)j.
Does internal energy of system depends upon volume?
Internal energy is an extensive state function. That means it depends on how much of a substance you have but if you fix the composition, pressure, temperature, volume, and (in the case of a system at a phase equlibrium point, like water at the freezing point) the phase of a system, the specific internal energy will be constant. If you take a closed system and change the volume of it, you will be doing work (or allowing the system to do work) and the internal energy can change - so - yes - internal energy of a system depends upon volume. Also, if you fix the composition, temperature, pressure, and phase of a homogeneous mass but change the volume, you will increase the amount of mass you included in the system, thus changing the total internal energy (because it is, after all, an extensive function).
