A Silly Question!!!!

VITEEE 2015 Help › Thermal physics questions › A Silly Question!!!!

A meter scale made of stell is calibrated at 20Â°C to give correct reading. Find the distance between 50 cm mark and 51 cm mark if the scale us used at 10Â°C. Coefficient of linear expansion of stell is 1.1 X 10 ^-5 /Â°C.
Ans. 1.00011 cm
just explain me that why the distance bet. them is increasing???
