Consider each of the following processes and determine if work is done by the system, work is done on the system or no work is done. work done on the system N2 (1) N2 (9) work done by the system Ca3P2 (s) + 6 H20 (1) + 3 Ca(OH)2 (s) + 2 PH3 (9) work done by the system' 2 CH3OH (1) + 3 02 (9) 2 CO2 (9) + 4H20 (1) work done on the system 3 NO2 (9)...
If a system has 375 kcal of work done to it, and releases 5.00 x 10 kJ of heat into its surroundings, what is the change in internal energy (AE or AU) of the system? - - AE = |
A gaseous system has 76 J of work done on it by surroundings and increases its internal energy by 17 J. Calculate the amount of heat associated with this scenario.
A system absorbs 12 of heat from the surroundings; meanwhile, 28 of work is done BY the system. What is the change of the internal energy of the system? -40 J -16 J 16 J 40 J
If a system has 3.50 x 102 kcal of work done to it, and releases 5.00 x 102 kJ of heat into its surroundings, what is the change in internal energy (AE or AU) of the system? AE=
Both energy and entropy can be transferred between a system and surroundings by heat, work and mass flow. True or False
True or False The value created by a business is created by it's assets.
Question 1 Calculate ΔEΔE, if a system releases 66.7 kJkJ of heat to its surroundings while the surroundings do 48.0 kJkJ of work on the system. Qeustion 2 Calculate ΔEΔE, if the system absorbs 7.29 kJkJ of heat from the surroundings while its volume remains constant (assume that only P−VP−VP-V work can be done).
Question 13 1 pts When heat is absorbed by the system and work is done by the system on the surroundings then both q and ware positive. both , and w are negative. O qis positive and wis negative. qis negative and wis positive. both q and w are zero. 1 pts
True or False? Explain. (it's true, but I need explanation) If the reduced cost of a product (decision variable) is positive, then the objective function will decrease by the amount of the reduced cost if an additional such product is produced.
