The laboratory is full of chemicals and other hazardous substances. So, it is very important to keep all the safety precautions before entering in the laboratory to avoid any mis-happening.

Here are some precautions, which one should take before entering lab:

Before entering the laboratory one must wear all the safety equipment including gloves, goggles, apron, and others.
Make sure you are not wearing any inflammable thing and you are fully covered, as in some laboratory, harmful radiation are also present.
Make sure your hair are tied in properly and the shoes are covered.

In an experiment, a researcher measures the mass of an object and gets the following results: 6.08 g, 6.07 g, 6.13 g, 6.09 g. Th

Considering the definition of accuracy adn precision, the results are accurate and precise.

<h3>Definition of accuracy and precision</h3>

Accuracy is the degree of closeness of the value of the measurements with respect to the real value of the magnitude. The closer a measurement is to the true value, the more accurate it is.

On the other hand, precision is defined as the proximity between the measured values in repeated measurements, under specified conditions; that is, there is more precision the closer the values of different measurements ar

In summary, accuracy is how close a measurement is to the true value, while precision is how close the values of several measurements are to a point.

Accuracy and precision are independent of each other. The results in the values of a measurement can be precise and not exact (and vice versa).

In an experiment, a researcher measures the mass of an object and gets the following results: 6.08 g, 6.07 g, 6.13 g, 6.09 g.

So, the measurement is quite precise, since the results of each individual measurement are quite similar.

Also, the actual mass of the object is known to be 6.10 g, so the measurement can be considered accurate.

In summary, the results are accurate and precise.
