Question 2 of 11 - /1 E On a linear X temperature scale, water freezes at -119.0"X and boils at 341.0%. On a linear Y temperature scale, water freezes at -64.00"Y and boils at -22.00"Y. A temperature of 50.00"Y corresponds to what temperature on the X scale? Number i UnitsQuestion 4 of 11 - /1 IE A vertical glass tube of length L - 1.4m is half filled with a liquid at 21.7 'C. How much will the height of the liquid column change when the tube is heated to 36.5 "C? Take Class - 1.40* 10 5/K and Bsquid - 4.32x 10.5/K. Number i Units mQuestion 3 of 11 -/1 At 18"C, a rod is exactly 23.37 cm long on a steel ruler. Both the rod and the ruler are placed in an oven at 230'C, where the rod now measures 23.59 cm on the same ruler. What is the coefficient of thermal expansion for the material of which the rod is made? The linear expansion coefficient of steel is 11 x 10"6 1/C. Number i UnitsTwo constant-volume gas thermometers are assembled, one with nitrogen and the other with hydrogen. Both contain enough gas so that pa - 80.0 kPa. (a) What is the difference between the pressures in the two thermometers if both bulbs are in boiling water? (Hint: See the figure.) (b) Which gas is at higher pressure, nitrogen or hydrogen? 373.50 2 373.40 373.125 K N: 375.30 Temperature 373.20 H 375.10 He 40 60 80 100 120 (L.Pa) Indications of the constant-volume gas thermometer for a boiling point of water depending on pressure at the triple point of water for various gases (a) Number 109.277 Units kPa (b) nitrogen vQuestion 5 of 11 -/1 Samples A and B are at different initial temperatures when they are placed in a thermally insulated container and allowed to come to thermal equilibrium. Figure (a) gives their temperatures T versus time t. Sample A has a mass of 5.21 kg: sample B has a mass of 1.34 kg. Figure (b) is a general plot for the material of sample B. It shows the temperature change AT that the material undergoes when energy is transferred to it as heat Q. The change AT is plotted versus the energy Q per unit mass of the material, and the scale of the vertical axis is set by AT, - 4.40 *C. What is the specific heat of sample A? 100 AT 60 AT(C ) 20 4 10 (min) Q/m (1J/kg) (a) (8) Number Units
