Aquatic animals can breathe underwater because of the presence of dissolved oxygen in water, essential for their survival.
Tiwari Academy Discussion Latest Questions
Diffusion of gases like oxygen and carbon dioxide into water ensures their availability for aquatic organisms’ respiration and photosynthesis, vital for their survival and ecosystem balance.
Oxygen and carbon dioxide, among other gases, are crucial for the survival of aquatic animals and plants as they are involved in respiration and photosynthesis, respectively.
Gases from the atmosphere can diffuse into liquids, such as water, and dissolve within them.
Diffusion is the process by which particles spread out to fill the available space. Both solids and liquids can diffuse into other liquids.
Liquids flow and can change shape, making them fluid rather than rigid like solids.
Liquids have no fixed shape but possess a fixed volume, taking the shape of the container they occupy.
Solids have fixed shapes and volumes, unlike liquids and gases, and they exhibit negligible compressibility, making them distinct in their physical properties.
Solids are considered rigid because they are difficult to deform or change their shape, maintaining their structural integrity.
Solids tend to maintain their shape under outside force, although they may break under excessive force.
