###### Question:

Dr. Terror has developed a new alloy called Ultranomium. He is testing a bar that is 1.35 m long and has a mass of 362 g. Using a carbon dioxide infrared laser, he carfully heats the bar from 23.6 °C to 268 °C. Answer the two questions below, using three significant digits. Part A: If the bar absorbs 80300 J of energy during the temperature change, what is the specific heat capacity (c) of the Ultranomium? J/(Kg) Part B: He notices that at this new temperature, the bar's length has increased by 0.0014 m. What is the coefficient of linear expansion (a) for the new alloy?

Using a carbon-dioxide infrared laser, he carfully heats the bar from 23.6 °C to 268 °C. Answer the two questions below, using three significant digits. Part A: If the bar absorbs 80300 J of energy during the temperature change, what is the specific heat capacity (e) of the Ultranomium? C= I J/(Kg) TOOLS Part expansion (a) for the new alloy? x10 temperature, the bar's length has increased by 0.0014 m.
