Aring made from brass has an inner radius of 2.5 cm and an outer radius of 3.5 cm, giving the ring a thickness of 1. cm. the thermal expansion coefficient of brass is 0.19/°c. if the temperature of the ring is increased from 20.0°c to 90.0°c, by how much does the thickness of the ring change? cm

0.00133 cm

Explanation:

Given

change in temperature

Thermal Expansion coefficient of brass
