Question
Volume of H_2O in 150 mL beaker Volume of H_2O in 25 mL Erlenmeyer flask Volume of H_2O in 100 mL graduated cylinder Volume of H_2 O in 10 mL graduated cylinder What change did you notice occurring in your reading of the volume of water as it was transferred from one piece of glassware to the next? What could cause a change in the volume reading of the sample between each piece of equipment if it was assumed that all water did transfer? If you needed to measure 10 Ml of a liquid which of the pieces used would you predict to given the greatest degree of accuracy and why?Explanation / Answer
There are four glasswares-
150mL beaker - 10.5 mL
25mL flask - 11 mL
100mL graduated cylinder - 9.9 mL
10ml graduated cylinder - 9.8 mL
1- There are 4 glasswares in which first one has highest volume, and second one is low. if we do properly there will be a differennce can be occurs because the large glass ware have more surface area where some water will remains in the beaker. It causes very tiny difference in measurement and vice versa.
2- Here is same explanation because here one larger glassware volume exchange its water with smaller glassware and vice versa. For a small volume would have better reading in smaller glassware. when 1st glassware exchange its water with 2nd glassware it would give more accuracy. when 3rd transfer with 4 it would also give more accuracy. The measurement parameter given in the glassware depend on the volume of the glasswares.
3- We would prefer 10 mL graduated cylinder because it gives more accuracy compare to other three glasswares. This 10mL graduated cylinder have measurement parameter for only 10ml while the other have highest.
