Find net heat transfer for change-specific internal energy
2.6 kg of air in a stationary box undergo a process that results in 22.3 kJ of work being done by the air (say there was a combustion process). Find the net heat transfer for the process if the change in specific internal energy is +55 kJ/kg.

(A) Assuming no heat is released to the surroundings, what is the final temperature of the lemonade? (B) What is the final temperature if you add 6, instead of 2, ice cubes.
In 2.00 min, 29.7 mL of He effuse through a small hole. Under the same conditions of temperature and pressure, 10.0 mL of amixture of CO and CO2 effuse through the hole in thesame amount of time.
Three charges q = 0.380 C form an equilateral triangle, 1.60 m on a side. Using energy that is supplied at the rate of 0.65 kW, how many days would be required to move one of the charges to the midpoint of the line joining the other two charges?

The two intervals (114.4, 115.4) and (114.1, 115.7) are confidence intervals for ? = true average resonance frequency (in hertz) for all tennis rackets of a certain type. What is the value of the sample mean resonance frequency?
The actual specific heat capacity of water vapor at low pressure is about 2000 J/kg*K. Compare this with your calculation and comment on the actual role of vibrational motion.
