What is an erlenmeyer flask and its function?
Erlenmeyer flasks: suitable for heating solutions enjoy reading and answering your assignment..... Heheheeheh may god bless you always...................
When can an Erlenmeyer flask be used instead of a beaker?
I my experience the Erlenmeyer flask is better for certain things than others.... what I mean is that is has labeled measurements on the side and the increments are based on the size of the flask but the volumetric flask is better is you want to dilute a solution at a certain volume to find....molarity they both have good qualities it just depends on what you want to use it for.
Does the shape of a beaker and an erlenmeyer flask affect accuracy in measurements?
They are not very good for measuring very small volumes. For reasonable amounts, because the beaker is of uniform cross section, the absolute measurement error is constant whereas the cross-sectional area of the Erlenmeyer flask decreases so that the absolute error decreases with increased volume. Finally, whichever container you use, great care must be taken to read the meniscus properly.
How do you use an erlenmeyer flask?
Erhlenmeyer flasks are particularly good for mixing and making solutions. They have a broad, flat base for sitting on tables without spilling easily, and the narrow necks makes it difficult for the contents to splash out. To mix solutions in an Erhlenmeyer flask, hold it by its neck and move it in a circular pattern. The liquid will"swish" around and mix quickly.
Is melting wax a solid liquid or gas?
that's a good question. It is a amorphous solid because it expands or gradually loses shape.
What is an element that is a shiny black solid and gives off a purple vapor when heated?
Iodine ------------------------------------------- The element you describe sounds like iodine, a good test to make sure that it is iodine is to see if the substance sublimes. This means a solid sample of iodine will turn straight from a solid into a gas with no liquid stage.
How do clean a beaker?
Acid washing it should do. I assume you are in a lab...in which case a 1:1 Hydrochloric Acid solution can be poured into the flask. DON'T FORGET TO PUT GOGGLES AND GLOVES ON. Put the lid on. Shake the flask and turn it to ensure all surfaces of the glass inside are being washed with the acid. Then, give it a good triple rinse with de-ionized water. If you are just at home, pour in some white vinegar and let it sit for a while. That should break up anything that's inside.
Must a flask be a good conductor of heat?
No, a flask does not necessarily have to be a good conductor of heat. In fact, many flasks are designed with insulating materials to help maintain the temperature of the liquid inside, whether hot or cold. So, a flask can be effective at keeping beverages hot or cold without being a good conductor of heat.
Should you use a flask which is a good conductor of heat or poor conductor to keep the tea inside the flask warm?
You should use a flask that is a good insulator or poor conductor of heat to keep the tea warm. This will prevent heat from escaping the flask and help maintain the temperature of the tea for a longer period of time.
What is shiny black solid but gives off a purple vapor when heated.?
You think to iodine.
Is a thermos flask also good for keeping water cold for several hours?
Yes. The thermos flask can reduce the amount of heat travelling from the surroundings to the cold water
What is the main cause of heat loss in a normal thermos flask?
The main heat loss in a good thermos flask, is due to heat conducted through the material. (Glass or Stainless Steel). There should be little heat lost through the vacuum of the flask.
