Amonatomic ideal gas that is initially at a pressure of 1.50 * 105 pa and has a volume of 0.08 m3 is compressed adiabatically to a volume of 0.0400 m3 . (a) what is the final pressure? (b) how much work is done by the gas? (c) what is the ratio of the final temperature of the gas to its initial temperature? is the gas heated or cooled by this compression

Question 7 [2 marks] in the circuit below, the electromotive force generated by the battery is e = 6.0 v, and the resistances are r1 = r4 = 1.0 q, r2 = r3 =2.0 q. r. the power delivered by the battery to the circuit is closest to a. 6 w в. 12 w с. 15 w d. 18 w e. 20 w final exam autumn 2014 page 5 of 9 68037 physical modelling faculty of science [2 mark] question 8 with reference to question 7, the current through resistor r2 is closest to a. 1 a в. 2 а c. 3 a d. 4 a e. 6 a
