Unformatted text preview: X is or is not an extensive property. Give a reason that X is or is not an intensive property. 5. Calculate the work done when 50 g of iron reacts with hydrochloric acid to produce hydrogen gas in (a) a closed vessel of ﬁxed volume, and (b) an open beaker at 25 ◦ C. 6. When a ball of mass m is dropped through a height diﬀerence Δ h , its potential energy changes by an amount mg Δ h , where g is the acceleration of gravity, equal to 9.81 m/s 2 . Suppose all this energy gets dissipated into the internal energy of the ball once it has stopped bouncing. If the speciﬁc heat of the material in the ball is 0.850 J/gK, calculate the height from which the ball must be dropped to increase the temperature of the ball by 1.00 ◦ C. 7. Discuss the proposition that, to a certain degree of approximation, a living organism is a steadystate system....
