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...
It 345 KJ of energy is transferred to a system as heat while the system does 42 kJ of work, what will be the change in internal energy of the system after the processes ar completed ?
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. Suppose 1500 Joules of work is done on a system, and 300 Joules of heat are delivered to the system. What happens to the internal energy of that system? b. What is the efficiency of an engine that takes in heat at 200oC, and rejects heat to the environment at 25oC? Big Hint: REMEMBER to work in Kelvin. c. Bernoulli’s equation shows that pressure in a fluid will tend to drop as velocity increases. Assuming a wind speed...
The air inside a bicycle tire pump has 24.8 joules of heat conducted away from while 53 joules of work done are being done on it. What is the change in internal energy of the air?
If 140 J of work is done by a system while 420 J of heat is transferred out of the system, what is the change in the internal energy of the system?
If a system absorbs 258 J of heat from the surroundings while it does 123 J of work, what is the change in internal energy of the system? Report your answer with three significant figures. Do NOT include units in your answer.
Air in a balloon does 32 J of work while absorbing 79 J of heat. What is its change in internal energy?
An automobile engine generates 2124 Joules of heat that must be carried away by the cooling system. The internal energy changes by -2679 Joules in this process Calculate w for the engine. This represents the work available to push the pistons in this process Joules W SmeatIOn A chemical reaction is run in which 486 Joules of heat are absorbed and 556 Joules of work are done on the system Calculate the change in the internal energy of the chemical...
A system does 1.80 x 10 8 J of work while 7.5 x 108 J of heat transfer occurs to the environment. What is the change in the internal energy of the system assuming no other changes, such as temperature, occur?
