Read the following paragraph and answer the questions given below:
Most spiders live on land , but this spider is different. It spends most of its time under
water. How does it breathe? It breathes by making a tent full of air bubbles under water.
First spins a web in the shape of a bell. Then it fixes it to plants under the water and
traps a tiny bubble of air with its hairy back legs. It drags the bubble to its web. It does this
many times until its home is full of air. Then it sits nice and snug in its wed and feeds on
tiny fish and other water animals.
Questions:
i) What is the shape of the webspun by the spiders?
ii) Where does the spider leave and how does it breathe?
iii) How does it trap a tiny bubble of air?
iv) How does it fill its house with air

Answer:
Adiabatic process : An adiabatic process is one that occurs without transfer of heat or matter between a thermodynamic system and its surroundings. In an adiabatic process, energy is transferred only as work.The adiabatic process provides a rigorous conceptual basis for the theory used to expound the first law of thermodynamics, and as such it is a key concept in thermodynamics.
Some chemical and physical processes occur so rapidly that they may be conveniently described by the "adiabatic approximation", meaning that there is not enough time for the transfer of energy as heat to take place to or from the system.okk
