It is observed that 55.50 mL of water at 20°C completely fills a container to the brim. When the container and the water are heated to 60°C, 0.35 g of water is lost. (a) What is the coefficient of volume expansion of the container? (b) What is the most likely material of the container? Density of water at 60°C is 0.98324 g/mL.

Volume of water that spilled out 
= (0.35) * (0.98324) mL 
= 0.3441 mL 

Thus, the original volume 
55.50 mL increased to 
55.8441 mL 

V(t) = Vo [1 + γ(60.0 - 18.7)] 
=> coefficient of volume expansion, 
γ = (Vt - Vo) / [Vo * 41.3] 
= (0.3441) / [(55.50) (41.3) 

 = 1.5012 x10^-4
