Describe the devices used to measure the volumes of liquids in the laboratory.
Answers
Volumetric Cylinders-These are used to measure the volume of liquids which is contained in those cylinders only. They are calliberated for volume included in them. Usullay liquid has accurate volume when it reches IN marked on the scale.Volume can also be compared with the density of liquid.Volume is measured in mL.
Answer:
The devices used are to measure the volumes of liquids in the laboratory are measuring cylinders, flasks and measuring beakers
Explanation:
Measuring flask: A measuring flask is a glass jar with a long narrow neck. It is used to measure out a definite quantity of liquid. The capacity is marked in millilitres. A ring marked on the neck indicates the level to which the liquid should be filled. Flasks of different capacities are used for measuring out different volumes.
Measuring cylinders: A measuring cylinder is a tall cylindrical jar made of glass or plastic. It has volumes marked on the outside in millilitres. There is a spout at the top for pouring out liquids easily. Different volumes of liquid can be measured using a measuring cylinder. Measuring cylinders of different capacities are available.
Measuring beakers: They are broader and shorter than measuring cylinders and graduated only in 25ml or 50ml. They are used when a precise measurement is not needed.
