What is the use of burner in laboratory apparatus?
The lab burner (sometimes referred to, and often erroneously so, as the Bunsen burner) is an indispensible tool for doing general chemistry lab work. It can be used to heat samples with high or low heat, for sterilization, to bend glass tubing or rods, or for other purposes.
What is the function beaker?
Beakers are useful as a reaction container or to hold liquid or solid samples. They are also used to catch liquids from titrations and filtrates from filtering operations.
What is the function of the test tube?
Test tubes are widely used by chemists to hold, mix, or heat small quantities of solid or liquid chemicals, especially for qualitative experiments and assays. Their round bottom and straight sides minimize mass loss when pouring, make them easier to clean, and allow convenient monitoring of the contents.
How much energy is in a flame?
Deep red fire is about 600-800° Celsius (1112-1800° Fahrenheit), orange-yellow is around 1100° Celsius (2012° Fahrenheit), and a white flame is hotter still, ranging from 1300-1500 Celsius (2400-2700° Fahrenheit). A blue flame is the hottest one of all, ranging from 1400-1650° Celsius (2600-3000° Fahrenheit).
