Answer:
Heat transfer for a internally reversible process.
Explanation:
Internally reversible means that there is entropy generation ' with in ' the system.
Heat transfer of a process is considered to be reversible if it occurs because of any minute temperature difference between the surrounding and the system .
Let us consider an example ,
Transferring of the heat across the difference in temperature of 0.0001 °C appears as more reversible than for the difference in temperature of 100 °C .
Hence ,
By heating or cooling a system for a number of infinitesimally small steps , we can approximate a reversible process.
so the answer is f because your a faliure so get out of here you fatty
Answer and Explanation:
The answer is attached below
Answer:
This can be achieved through the use of a built-in fiber-optic network of cables that deliver light and heat energy to the point of breakage.
Explanation:
Self-healing polymers are materials designed to aid the internal healing of materials like plastics, and metals. Shape-memory materials used in the making of plastic frames for glasses and sunglasses allow these materials to snap back into shape when they crack.
This is possible because heat is needed to help a deformed material regain its shape. Built-in fiber-optic network of cables serve the purpose of delivering heat to the deformed or cracked area, thus helping them to regain their shape.
