A steel railroad track with Young's modulus = 2 x 101" Pa and a coefficient of thermal expansion = 11 x 106/°C. It is fixed and nailed down so it cannot expand when the temperature is 0°C. What stress will result if the temperature increases to 65 °C? Answer should be in Mega Pascal.

Suppose you have a closed rigid container of air at 20 Celsius on the surface of the Earth. We increase the temperature of the container to 77, leaving it closed, and read a pressure gauge attached to the container. Initially the reading was 101 KPa (kilopascals, or 1000 N/m2). What is the new reading? Give your answer in KPa.
