What are the difference between single pan balance and double pan balance?
The weight is measured by means of one or more bars (levers) with sliding weights that are marked with the exact weight that balances the contents in the pan. So the principle is a simple lever with weights on on one side of the fulcrum that balance the weight of the unknown object in the pan.
What are the advantages of analytical balance?
An analytical balance is typically defined as a balance with a display resolution of 0.1mg. Usually it will have a draft shield around it. Although it can be used to describe any precision balance.
Why are hot objects never placed on a balance pan?
Because it Will burn through the balance pan
What is a pan balance made out of?
A pan balance is made out of two pans, two chains depending on how long youwant them, a piece of metal depending on how long you want it to be and twopieces of wood to make the stand for the scale.
Is it acceptable to determine the mass of a chemical sample by placing it directly on the pan of the balance?
Yes it is, as long as the balance is accurate.
Why is the iron weighed accurately on an analytical balance while the copper sulfate is weighed on a top-pan balance?
Because
What are the advantages and disadvantages of having a pan?
You can hit someone with it
What are the advantages and disadvantages of balance scale?
A top-pan balance has the advantage of being very simple to use. The user simply places the object to be weighed on the top pan and reads the corresponding weight from the scale. A top-pan balance also has the advantage of being very accurate, as long as it is properly calibrated. A top-pan balance also has several disadvantages. First, it can only be used to weigh objects that can be placed on the top pan. Second, the top pan is often very small, which limits the size of the objects that can be weighed. Finally, top-pan balances are often less sensitive than other types of balances, which means that they are not well suited for weighing very small objects.
What is analytical and top pan balance?
Analytical balances are those which weigh with a precision of 0.0001g (0.1mg) or better. Typically these balances have the platform enclosed within a large draft shield to help stabilize the readout. Top pan balances, or toploader balances are used to describe balances with one weighing pan on the top of the device.

How do you zero the balance on a pan balance?
remove all objects from the pan balance
Does a pan balance measure mass or weight?
does a pan balance measure weight
Uses of analytic balance?
An analytical balance is used to measure mass to a very high degree of precision and accuracy. The weighing pan(s) of a high precision (.01 mg or better) analytical balance are inside a transparent enclosure with doors so that dust does not collect and so any air currents in the room do not affect the balance's operation. The use of a vented balance safety enclosure, which has uniquely designed acrylic airfoils, allows a smooth turbulence-free airflow that prevents balance fluctuation and the weighing of mass down to 1 μg without fluctuations or loss of product. Also, the sample must be at room temperature to prevent natural convection from forming air currents inside the enclosure, affecting the weighing. Analytical precision is achieved by maintaining a constant load on the balance beam, by subtracting mass on the same side of the beam to which the sample is added. The final balance is achieved by using a small spring force rather than subtracting fixed weights.
How do you balance an object on a triple beam balance?
Find the pan of the triple-beam balance and place the object in the center of the pan.

What are the advantages and disadvantages of personal area network?
Advantage is PAN users can move without much concern of their mobile devices I/O redundancies. Disadvantage is the PAN has limited transmission range about 10 meters.
Different parts of analytical balance?
*weighing pan *adjustable feet *wind screen *level indicator *on/ off switch *LCD Display *zero switch *mode switch *function switch *subpan *send switch
