What is climate ? |
The average weather conditions that occur in a region over a long period of time. |
|
|
Common chemical properties |
Ability to burn (heat ,light) Flash point( temp needed to ignite flame) Behaviour in air ( degrading, react, or tarnish) Reaction with water ( tendency to corrode or dissolve) Reaction with acids ( corrosion, sometimes bubble formation) Reaction to heat ( tendency to melt or decompose) Reaction to red and blue litmus ( red- acid;blue -base; no colour change - neutral |
