glass cylinder
To determine which graduated cylinder is suitable for use, you need to consider the volume of the chemical that needs to be measured and heated.
1. Determine the volume: Find out the volume of the chemical you need to measure. This can be done by referring to any experimental instructions or by estimating the expected volume range.
2. Choose an appropriate capacity: Graduated cylinders come in various sizes, typically ranging from 10 mL to 1000 mL or more. Based on the estimated volume, choose a cylinder with a capacity slightly higher than the expected volume. It is important to leave some extra space to prevent spillage when heating or transferring the chemical.
3. Consider the precision: If you require precise volume measurements, opt for a graduated cylinder with smaller gradations (marked lines) on the scale. For general use, a cylinder with larger gradations can be sufficient.
4. Check for heat resistance: Ensure that the chosen graduated cylinder is heat-resistant. Most graduated cylinders made of borosilicate glass or certain plastics such as polypropylene are suitable for heating. Avoid using cylinders made of regular glass or materials that may break or melt when exposed to heat.
By considering the volume, precision, and heat resistance, you can select a suitable graduated cylinder for measuring and heating the chemical in Susan's experiment. Remember to always follow any specific guidelines provided by the experiment instructions or safety protocols.
