Question

Need answer to this question on Thermal expansion so that i can compare my solutions to yours;
a) A street, 6 m wide, is made of concrete plates which are 6.00 m wide, 12.0 m long and 25.0 cm thick, and which are, at 20.0 °C, connected by 1.00 cm wide jo intings filled with tar. Calculate the tar volume oozing out of one jointing at a hot summer day at 35.0 °C.
Use: Alpha con = 14.0 •10-6 K-1, ßtar = 6.00 •10-5 K-1
