[mwit1967]

Three moles of an ideal gas with a molar heat capacity at constant volume of 4.9 cal/(molK) and a molar heat capacity at constant pressure of 6.9 cal/(molK) starts at 300 K and is heated at constant pressure to 320 K,
 
  then cooled at constant volume to its original temperature. How much heat flows into the gas during this two-step process?
  A)
 
  710 cal
 
  B)
 
  -720 cal
 
  C)
 
  0 cal
 
  D)
 
  120 cal
 
  E)
 
  -120 cal

D

Answer to Question 2

In a transverse wave, the vibration of the particles of the medium is perpendicular to the motion of the wave itself. In a longitudinal wave, the vibration of the particles of the medium is along the direction of the wave's motion.
