Laboratory Tools and Functions

A clay triangle is primarily used to support a crucible while it is being heated.
Tongs are used to safely lift hot crucibles from a furnace, preventing burns or accidents.
An iron stand provides stability and support for various laboratory apparatus during experiments.
A ring stand or support ring is designed to hold beakers, flasks, and other glassware securely during experiments.

Properties and Composition of Matter

A graduated cylinder is utilized for accurate measurement of liquid volume, allowing precise experimentations.
Matter is primarily composed of atoms, which are the building blocks of all substances in chemistry.
The gaseous state of matter features particles that are spaced apart and can move rapidly, contributing to gas expansion.
Boiling point is classified as a physical property, indicating the temperature at which a substance transitions from liquid to gas.

Elements and Compounds

An example of a non-metal element is oxygen, which is essential for various chemical processes.
A pure substance is made up of only one kind of particle and has a fixed structure, ensuring uniform properties throughout.
A beaker or graduated cylinder is commonly used for measuring liquid volume accurately in laboratory settings.

Chemical Bonds and Laboratory Functions

Metal elements typically exhibit metallic bonding, characterized by a sea of delocalized electrons allowing conductivity and malleability.
An alcohol lamp is primarily used for heating substances or providing a controlled flame in laboratory settings.
An incubator or Petri dish is specifically designed for culturing bacteria and molds, facilitating biological experiments.

Miscellaneous Laboratory Apparatus

A watch glass serves as a cover for beakers or as a surface for evaporating small amounts of liquid, preventing contamination.
An evaporating dish is best suited for containing liquid samples that require evaporation, promoting efficient separation of solids from liquids.
A cabinet or shelf is intended to contain and store various chemicals, either in liquid or powder form, ensuring safe and organized laboratory environments.
