A vessel of glass of constant volume contains 340g of mercury at 0^(@)C. When a few spherical iron balls are dropped into the vessel, 85g of mercury flow out. When the system is heated to 100^(@)C, 4.8g more of mercury flows out. Calculate the coefficeint of linear expansion of iron. (gamma_("mercury"=180xx10^(-6)K^(-1))

1.	A vessel of glass of constant volume contains 340g of mercury at 0^(@)C. When a few spherical iron balls are dropped into the vessel, 85g of mercury flow out. When the system is heated to 100^(@)C, 4.8g more of mercury flows out. Calculate the coefficeint of linear expansion of iron. (gamma_("mercury"=180xx10^(-6)K^(-1))
Answer» ANSWER :`11.8xx10^(-6)K^(-1)`
