ΔU =
During a process a system releases 12.4 J of heat and does 4.2 J of work on the surroundings. The change in internal energy (ΔU) of the system is _____ J. and the answer is not -8.2
A system does 181 J of work on its environment and gains 98.3 J of heat in the process. Find the change in the internal energy of (a) the system and (b) the environment.
In process A, 48 J of work are done on the system and 72 J of heat are added to the system. Find the change in the system's internal energy. In process B, the system does 48 J of work and 72 J of heat are added to the system. What is the change in the system's internal energy? In process C, the system's internal energy decreases by 129 J while the system performs 129 J of work on its...
A system releases 110 J of heat and does 345 J of work on the surroundings. What is the change in internal energy (AU) of this system (in J)?
1.) A system absorbs 1.56E+2 kJ of heat and the surroundings do 1.107E+2 kJ of work on the system. What is the change in internal energy (in kJ) (ΔU) of the system? 2.) A sample of gas in a cylinder is provided with 6.221E+2 kJ of heat. This causes a piston to then compresses the gas by doing 4.343E+2 kJ of work to the gas. What is the change in internal energy of the gas during this compression? 3.)A gas...
Three different processes act on a system. In process A, 53 J of work are done on the system and 77 J of heat are added to the system. Find the change in the system's internal energy. In process B, the system does 53 J of work and 77 J of heat are added to the system. What is the change in the system's internal energy? In process C, the system's internal energy decreases by 125 J while the system...
400 J of heat is added to a system. If the change in internal energy of the system was 850 J, how much work was done on by the system? the inside a container absorbs 250 J of hea while 125 J of work is done on it and then does 70 J of its own work, by how much does the internal energy of the gas increase? 7.500 joules of heat is added to a system while it also...
A system does 2.90 ✕ 108 J of work while 9.40 ✕ 108 J of heat transfer occurs to the environment. What is the change in internal energy of the system assuming no other changes (such as in temperature or by the addition of fuel)? (Include the sign of the value in your answer.) J
A system does 2500 J of work on the environment in the process, his internal energy decreases by 1500 J. Determine the value of heat exchanged during this process, 1,100 O 10,000 100 1.0*10')
Suppose the work done to compress a gas is 100 J. If 70 J of heat is lost in the process, what is the change in the internal energy of the gas? Hint: Use the first law of thermodynamics. The internal energy of a system changes due to heat (Q) and work (W): U=Q-W. The change in internal energy is equivalent to the difference between the heat added to the system and the work done by the system. Think if...
