It is necessary to determine the specific heat of an unknown object. The mass of the object is measured to be 199.0 g.
 
  It is determined experimentally that it takes 16.0 J to raise the temperature 10.0C. Find the specific heat of the object.
  A) 8.04 J/kg  K
  B) 1600 J/kg  K
  C) 0.00120 J/kg  K
  D) 3.18  106 J/kg  K

Question 2

During an adiabatic process, 20 moles of a monatomic ideal gas undergo a temperature change from 450 K to 320 K starting from an initial pressure is 400 kPa.
 
  The ideal gas constant is R = 8.314 J/mol  K.
  (a) What is the final volume of the gas?
  (b) How much heat does the gas exchange during this process?
  (c) What is the change in the internal (thermal) energy of the gas during this process?
