HT 2 - Temperature Scales and Thermal Expansion - Assignment This assignment covers section HT 5. 1. A 0.350 m gold bar at 20.0'C heats up to 500.0'C. What is the change in length of the gold bar? 3 1 2. What temperature in degrees Celsius is 435 K? 3. A 1.000 m aluminum bar at 30.00'C cools to a temperature of -50.00-C. What is the final length of the bar? 3 4. A large container is holding 2.50 L of mercury. What is the change in volume of the mercury if it experiences a temperature change of 78.0*C (assuming the temperature of the container remains constant)? 3 5. A container of water at 30.0'C experiences a volumetric change of 5.00 x 10-3 L. If the original volume of water was 425 mL, what temperature change did it go through? 36. A contractor installing a window in a new building must be aware of the thermal expansion it will undergo to make sure it doesn't crack in its lifetime. The dimensions of the rectangular window are 4.65000 m by 12.1950 m. If the temperature during installation is 12.5000 'C and it drops to -22.0000*C overnight, what is the change in area of the window? 7
