What is the meniscus rule used for?
The meniscus rule states that you always measure the volume of a water-based solution from the bottom of the meniscus when you are using a graduated cylinder.
Why is it important to be sure that no drops of water cling to the cylinder in the water displacement method?
The drops of water could potentially add to the volume of an object, affecting the position of the meniscus. This will essentially give one inaccurate results when measuring volume.
How can you relate volume to a meniscus?
When measuring the volume of a liquid in a graduated cylinder, you read it at eye-level and at the bottom of the curve of the meniscus. This is true for water and aqueous solutions. Some "non-water" liquids do not form a meniscus in a glass cylinder. Also, water does not form a meniscus in a plastic cylinder.
Why does meniscus of water in glass curves upwards?
Adhesion to the test tube or cohesion of the liquid molecules causes the meniscus to form.
Is the curve at a liquids surface by which you measure the volume of a liquid?
The meniscus is the curve at a liquid's surface by which one measures the volume of the liquid. A meniscus can be concave or convex depending on whether it is attracted to itself or the glass.
When water is in a container the surface of the water is curved this curve is called?
The meniscus - the upward curve of a liquid in a narrow vessel.Read more: When_water_is_ina_container_the_surface_of_the_water_is_curved_this_curve_is_called
What is a synonyms for the science word meniscus?
water surface meniscus or knee cartilage meniscus?
What property would you be measuring if you were looking at a meniscus?
liquid
What property of H2O is associated with a meniscus?
surface tension
What liquid's meniscus curve up?
Water's meniscus curves up. Mercury's meniscus curves down.
What is the curve at a liquid surface?
The meniscus, which is creaded by adhesion of the liquid particles to the surface of the container. Water meniscus domes upwards - the water has greater bonding to its own molecules; Mercury meniscus domes downwards.
What is the lowest point of the water level in a graduated cylinder called?
It's called Ya Mum's Panis
When water is in a container and the water is curved What is the curve called?
This is called the meniscus. The meniscus is caused by the high surface tension of water.
Meniscus?
The top of the water.
What is a substance whose meniscus would curve downward?
Mercury's meniscus curves down. Water's meniscus curves up.
How does adhesion and cohesion results to the formation of a meniscus?
if adhesion>cohesion, concave meniscus from out if ahesion<cohesion, convex if adhesion=cohesion, flat surface
What is the zero correction and meniscus correction in hydrometer analysis?
· Zero Correction (Fz): If the zero reading in the hydrometer (in the control cylinder) is below the water meniscus, it is (+), if above it is (-), if at the meniscus it is zero.· Meniscus Correction (Fm): Difference between upper level of meniscus and water level of control cylinder.
