Ceramics must be heated in order to harden the clay and make it durable. The tool used to heat the clay is called a Kiln.
<h3>What happens when ceramic is heated?</h3>
Cristobalite is a silica polymorph that is used in ceramics. Quartz particles in porcelain can change into cristobalite during burning. This has effects on the fired matrix's thermal expansion. When there is a high level of vitrification or a shape is unstable during the firing of ceramic ware, warping occurs.
Ceramic items are porous, brittle, and rigid. They are thus employed in the production of glass, ceramics, cement, and bricks. Additionally, ceramics are employed extensively in gas turbine engines. Artificial bones and dental implants are both made of bio-ceramics.
Any of the several tough, fragile, heat- and corrosion-resistant materials created by sculpting and then heating an inorganic, nonmetallic material like clay to a high temperature are known as ceramics.
In order to solidify the clay and make ceramics durable, heat must be applied. A kiln is the name of the device used to heat clay.

A problem that will be handled by a procedure is described by an input-output specification.
<h3>What is input and output specification?</h3>
- An input-output specification outlines the issue that a procedure will try to solve. The input part and the output part are its two components.
- The input component outlines the kind of data object that should be provided for each actual argument as well as any presumptions that the process might make.
- A technical specification known as an output specification defines the project scope primarily through performance-based requirements.
- It is used to assess technical compliance and serves as the technical cornerstone of both the procurement and delivery phases.
- Known as classical specifications, they outline the precise services to be provided, sometimes in great detail, along with the standard you must meet and the approach you must take to meet the standard.

Answer:
(iv) second law of thermodynamics
Explanation:
The Clausius inequality expresses the second law of thermodynamics it applies to the real engine cycle.It is defined as the cycle integral of change in entropy of a reversible system is zero. It is nothing but mathematical form of second law of thermodynamics . It also states that for irreversible process the cyclic integral of change in entropy is less than zero
