What is the change in temperature on the Kelvin scale and on the Fahrenheit scale? 10 Thermal Expansion s What is thermal expansion? s Linear Expansion s Area expansion s Volume expansion 11 Applications of Thermal Expansion – Bimetallic Strip s Thermostats s Use a bimetallic strip s Two metals expand differently s Since they have different coefficients of expansion 12 Thermal Expansion – Example 1. A steel railroad track has a length of 30.00 m when the temperature is 0°C. What is its length on a hot day when the temperature is 40°C? 13 Thermal Expansion – Example 1. A hole of crosssectional area 100.00 cm 2 is cut in a piece of steel at 20°C. What is the area of the hole if the steel is heated from 20°C to 100°C? 14 Unusual Behavior of Water...
