Final answer:
The volume of a table tennis ball can be determined using water displacement in a graduated cylinder with the formula Vb = Vf - Vi. Record the initial and final volumes of water and calculate the difference to find the ball's volume.
Step-by-step explanation:
To find the volume of a table tennis ball (Vb), you can use a simple method involving water displacement in a graduated cylinder. You must take the initial volume of water (Vi) in the graduated cylinder and then note the final volume of water (Vf) after placing the ball in the cylinder. The difference between these volumes gives the volume of the ball according to the formula Vb = Vf - Vi. The steps are as follows:
- Fill a graduated cylinder with water and record the initial volume of water (Vi).
- Submerge the table tennis ball completely in the water without letting any air bubbles escape.
- Record the new volume of water (Vf).
- Calculate the volume of the ball (Vb) by subtracting the initial volume (Vi) from the final volume (Vf).
As an example, if the initial volume of water is 19.9 ml and after submerging the table tennis ball the final volume is 29.2 ml, then the volume of the ball would be 29.2 ml - 19.9 ml = 9.3 cm³.
