Answer:
2a. 3mL.
2b. 10mL.
3. 38°C.
Explanation:
2a. We read the volume under the meniscus i.e under the curve.
The volume of the solution is 3mL.
2b. The volume of the pipette 10mL and the solution is at the calibration mark. Therefore, the volume of the solution is 10mL.
3. From the diagram given, we can see that 1 line represents 1 unit.
Now a careful look at the picture shows that the temperature is 38°C.
