1) 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?
2) 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)?

On the Rankine temperature scale, which is sometimes used in engineering applications, the freezing point of water is at 491.67 °R and the boiling point of water is at 671.67 °R.
(i) Determine a relationship (a mathematical equation) between the Rankine and Fahrenheit temperature scales. (ii) A healthy person has an oral temperature of 98.6F. Calculate what this reading would be on the Rankine temperature scale.

Concrete sidewalks are always laid in sections, with gaps between each section. The drawing shows three identical 2.4-m sections. The outer two are against immovable walls. Two identical gaps between the three sections are provided so that thermal expansion will not create thermal stress that could lead to cracks. Calculate the minimum gap width necessary so that an increase in temperature of 32 C° will not cause cracking of the concrete sections.
