Answer to Question #51912 in Other Chemistry for vi
Expansion joints are used for materials that easily expand and contract depending upon its temperature. How much expansion can take place for a brass pipe 25.8 m long that experiences temperature changes of 75.2°C?
Lineartemperature expansion of brass is 18.7·10-6 1/(K). 1ºC=1 K Thatis why for 25.6 m pipe the expansion will be: 25.8·18.7·10-675.2=0.036 m=3.69 cm
