When using a measuring cylinder What precautions should you take?
State two precautions that should be taken when using the measuring cylinder.
- The measuring cylinder should be placed on a flat surface when reading the volume.
- The volume of the liquid should be read from the base of the meniscus.
What are 2 rules that must be followed when reading the volume from a graduated cylinder?
To correctly read a graduated cylinder, the surface at the center of the meniscus must be read, not the top of the ring of liquid clinging to the wall of the graduated cylinder. For most liquids, this “center” will be the lowest point of the meniscus.
What precautions should be followed while using LPG cylinder?
When Cooking with LPG
- Keep the doors and windows of your kitchen open for proper ventilation.
- Do not place flammable or plastic items near the flame.
- Never leave your cooking unattended.
- Wear clothes that do not catch fire easily.
- Close the regulator knob to OFF position when cylinder is not in use.
What precaution should be taken before making up the volume?
Answer Expert Verified. The line of sight must be perpendicular to measuring scale to avoid parallax error. Formation of bubbles inside the cylinder should be completely avoided. Any bubbles within leads to wrong measurements.
What precautions should be taken while measuring liquids with graduated cylinder?
State two precautions that should be taken when using the measuring cylinder. The measuring cylinder should be placed on a flat surface when reading the volume. The volume of the liquid should be read from the base of the meniscus.
How do you read volume in a graduated cylinder?
Determine the volume contained in a graduated cylinder by reading the bottom of the meniscus at eye level. Read the volume using all certain digits and one uncertain digit. Certain digits are determined from the calibration marks on the cylinder.
When measuring distance you should use a?
To measure distances in a field (for example the length and width of a field), a chain or a measuring tape is used. Two men are required, the back man, holding the zero point of the chain (or the tape), and the front man, holding the other end of the chain.
How can cylinder blasting be prevented?
How to prevent Gas Cylinder Explosion
- Keep the gas knob out of reach for children when not using.
- Make sure that the kitchen or cooking area is well ventilated for a good flow of air in case of a gas leak.
- Educate people around you on gas cylinder safety measures and how to use and handle gas cylinders.
What precautions should be taken while measuring the volume of liquid having concave meniscus?
Answer: The line of sight must be perpendicular to measuring scale to avoid parallax error. Formation of bubbles inside the cylinder should be completely avoided.
