The meniscus of a thermometer is the curve seen at the surface of a liquid in the thermometer tube. It is caused by surface tension and capillary action, and the measurement of temperature is taken at the lowest point of the meniscus. Reading the temperature correctly involves ensuring that the eye is at the same level as the meniscus.

What is a curved surface on a liquid called?
A meniscus, but whether it has a positive curve or a negative one depends on whether it wets the glass.
What is the scientific name for the curved water surface above the rim of a glass?
The curve you see on top of a liquid in a cylinder is called the meniscus and is due to the difference between the attractive force between the liquid molecules themselves and between the liquid molecules and the wall of the cylinder, as well as capillary action. When the molecules of the liquid have a greater attraction to the cylinder wall than to themselves, the meniscus is concave and the surface of the liquid curved downwards. Water drawn up a narrow glass cylinder has a concave meniscus. When the molecules of the liquid have a greater attraction to themselves than to the cylinder wall, the meniscus is convex and curves upwards. Mercury in a glass thermometer or barometer has a convex meniscus.
How is a meniscus used in measuring?
As the diameter of the container decreases, the meniscus becomes more pronounced. The meniscus may be convex (curving upward) or concave (curving downward). Most of the time you will find that the meniscus is concave. The most notable exception is the meniscus that forms from mercury. When taking measurement readings it is important that the reading is done properly. The following rules must be adhered to: I. Read the meniscus at eye level. Do not read the meniscus from above or below eye level. Significant measurement errors may occur II. Read the bottom of a concave meniscus and the top of a convex meniscus.
What is a saline meniscus test?
A saline meniscus test is a diagnostic procedure used to assess the integrity of the meniscus in the knee joint. It involves injecting saline solution into the knee joint to create a meniscus-like bulge. By evaluating the stability and response of this saline meniscus, healthcare providers can gather information about the condition of the knee's meniscus.
When measuring you do the measurement from the bottom of the meniscus?
You should always measure at the lowest part of the meniscus. The meniscus is a slight curvature at the top of a liquid in a container.
What is it called when in the middle of the thermometer it curves when you measure water?
This is called the meniscus. It occurs because of surface tension between the liquid and the walls of the thermometer. When measuring water, you should read the temperature at the bottom of the meniscus for an accurate measurement.
To get an accurate measurement on a thermometer what do you do?
- Read the temperature over the meniscus (for mercury thermometers)- Avoid the parallaxe error- Respect the depth of immersion thermometer- Don't use thermometers with defects (ex. air bubbles)- Wait a reasonable time the setting of indication for the thermometer

What is the lowest point of the water level in a graduated cylinder called?
It's called Ya Mum's Panis
What liquid's meniscus curve up?
Water's meniscus curves up. Mercury's meniscus curves down.
What part of the meniscus do you measure from?
You measure from the bottom curve of the meniscus.
What is the curved surface of a liquid called?

Why do they add red dye to colorless alcohol in thermometer?
The red dye is added to make it easier to read the temperature scale on the thermometer. The dye provides a contrast against the clear liquid, making it more visible and accurate to read the temperature markings.
Did you measure at the top of the meniscus or the bottom?
You measure at the bottom of the meniscus.
