What is a sensitivity balance in science?

Museo Galileo - In depth - Sensitivity of a balance. Sensitivity of a balance. A balance is said to be sensitive when it can register small differences in weight. The balance beam is most sensitive when its center of gravity lies slightly below its rotation axis.

How do you find the sensitivity of a balance?

Count the number of graph squares that cause the smallest detectable motion. Multiply that number of squares times the calculated mass of a single square to determine the balance's sensitivity.

What is the most sensitive lab balance?

Typically used in quantitative chemical analysis, analytical balances are extremely sensitive and are able to measure four decimal places to the right of the decimal point and capable of measure samples up to 320g. An analytical balance is so sensitive air currents can affect the measurement.

What is a balance called in science?

A scale or balance is a device to measure weight or mass. These are also known as mass scales, weight scales, mass balances, and weight balances.

What is a sensitivity weight?

Summary. A sensitivity weight is selected to calibrate the balance over the range to be used in the measurement procedure. Minimizing the difference in mass values between X and S is critical when choosing an appropriate sensitivity weight.

What is meant by sensitivity in physics?

Sensitivity describes the smallest absolute amount of change that can be detected by a measurement, often expressed in terms of millivolts, microhms, or tenths of a degree. ... The actual sensitivity is as much a function of the measurement device as it is the environment in which the measurement is being made.

What is sensitivity of an instrument?

Sensitivity may be defined as the rate of displacement of the indicating device of an instrument, with respect to the measured quantity. In other words, sensitivity of an instrument is the ratio of the scale spacing to the scale division value. ... It is also called as amplification factor or gearing ratio.

Why is it important to use a sensitive balance for a very small mass?

An analytical balance is so sensitive that it can detect the mass of a single grain of a chemical substance. Thus, if a method of direct weighing is used, the substance ought to be added to the tared container which will hold it, NEVER directly to the pan or even to weighing paper placed on the pan.

Which balance is used in laboratories?

Some examples of laboratory balances include the triple beam balance, analytical balance (a.k.a. precision balance or chemical balance), micro and semi-micro balances.

Which balance is used in laboratory?

Laboratory balances are normally used to measure the weight or mass of an object to a very high degree of accuracy. A few common balances used in labs today are precision balances, compact balances, and analytical balances with readability of 0.001 g, 0.01g, and 0.0001 g respectively.

What are examples of balance?

An example of balance is being able to walk on a tight rope. An example of balance is when a person divides his time evenly between work, family, and personal pleasure. An example of balance is a person who doesn't get upset very often and doesn't let the little things bother them.

What is balance in biology?

Balance: A biological system that enables us to know where our bodies are in the environment and to maintain a desired position. Normal balance depends on information from the inner ear, other senses (such as sight and touch) and muscle movement.

What are the four kinds of balances?

The four types of balance that can be used in art, design, and photography—symmetrical, asymmetrical, radial, and crystallographic.

What is analytical balance?

Analytical balances are highly sensitive lab instruments designed to accurately measure mass. Their readability has a range between 0.1mg - 0.01mg. Analytical balances have a draft shield or weighing chamber to prevent the very small samples from being affected by air currents.

What is accuracy in weighing balance?

The accuracy of a scale is a measure of the degree of closeness of the average value of an object's displayed weight to the object's actual weight. If, on average, a scale indicates that a 200 lb reference weight weighs 200.20 lb, then the scale is accurate to within 0.20 lb in 200 lb, or 0.1%.

What does a balance do in chemistry?

CHEMISTRY GLOSSARY

Balance is an instrument to measure the mass (or weight) of a body. Balance beam type scales are the oldest type and measure weight using a fulcrum or pivot and a lever with the unknown weight placed on one end of the lever, and a counterweight applied to the other end.
