3. T062:Q10. A metal rod has a length of 7.30 m at 15  C and a length of 7.40 m at 95  C. What is the temperature of the rod when its length is 7.21 m? (Ans: -57  C) Q10. What mass of steam initially at 100 o C should be mixed with 160 g of ice at 0 o C in a thermally insulated container to produce liquid water at 40 o C. (Ans: 32 g ) Q#15: 300 grams of water at 25 degree-C are added to 100 grams of ice at zero degree-C. The final temperature of the mixture is:( Ans: zero C  ) Q#7. Consider one mole of a monatomic gas taken through the cycle shown in the figure 2. Find the change in internal energy of the system for the adiabatic process a → b. (Ans: –100 kJ) Q#13: In a P-V diagram, a system of an ideal gas goes through the process shown in figure 2. How much heat is absorbed after the system goes 100 times through the cycle? (Ans: 300 J) Q2) A steel washer (ring) has an inner diameter of 4.000 cm and an outer diameter of 4.500 cm at 20 deg C. To what temperature must the washer be heated to just fit over a rod that is 4.010 cm in diameter? (Coefficient of linear expansion of steel, alpha, = 11*10**-6 per C deg) (Ans: 247 deg C ) T032: Q#12) A certain metal rod has a length of 10.00 m at 100.00 degree-C and a length of 10.04 m at 773 K.
