Answer 1

Answer:

lo..friend

here is the answer of ur question..

liquid don't have a definite shape but have a fixed volume ..it need a container to store them..and fills the container they maintain the same volume till the temperature changes also they can be compressed..this is because the inter-molecular space more than solid but less than gas..the inter-molecular force of attraction in liquids is weaker than solids..

gas neither have a fixed volume nor a fixed shape..they are easy to compress due to max. inter-molecular space...  they expand to fill their containers,  

hope u got the answer

1. The 4 layers of the rain-forest. There are four different layers of the rain-forest, each marked with different characteristics. They include the emergent layer, the upper canopy, the under-story (lower canopy), and the forest floor.
2. Forest play a crucial role in providing fresh air to breathe. During day time, plants and trees absorb carbon dioxide and release oxygen. Forests are vital because they stabilize the climate and provides a home to thousands of life forms. Trees help to recycle the earth nutrients by shedding leaves and small branches.
3. A biotic community, also known as a biota or 'biocoenosis', is the group of organisms that live together and interact with each other within an environment or habitat. Together, the biotic community and the physical landscape or abiotic factors make up an ecosystem.
