Question

Conventionally, volumes of all glassware are expressed at (20) •C. The expansion coefficient glass is 0.0025% per •C. if a flask is found by calibration to contain 100.09 ml at 20 •C, what is the volume of this flask at 29 •C?

Ps: •C is the unit of temperature
Ps: •C is the unit of temperature

Explanation / Answer

Change in Temperature from 29C = (29-20) = 9C

Expansion coefficient of glass = 0.0025%/C * 9C = 0.0225%

Volume of flask at 29C = Volume of Flask at 100 C * (1+0.0225/100)

=> 100.09 * (1 + 0.0225/100)

=> 100.11252

Hence the final answer will be 100.11 mL
