When a liquid is heated in copper vessel its coefficient of apparent expansion is 6×10−6∕‌°C. When the same liquid is heated in a steel vessel its coefficient of apparent expansion is 24×10−6∕‌°C. If coefficient of linear expansion for copper is 18×10−6∕‌°C, the coefficient of linear expansion for steel is

20×10−6∕‌°C
24×10−6∕‌°C
36×10−6∕‌°C
