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.

#SPJ4
Answer:
TOTAL ENERGY = 0.74 j
Explanation:
Given data:
spring constant is 350 N/m
m = 0.24 kg
b = 0.41 kg/s
A = 0.075 M




after one full cycle, mass will be at extreme point, hence K,E = 0
But total energy remain same
y after one full cycle is\

y = 0.06517 m
y = 6.517 cm
total energy 

Answer:
2
Explanation:
So for solving this problem we need the local heat transfer coefficient at distance x,

We integrate between 0 to x for obtain the value of the coefficient, so
Substituing

The ratio of the average convection heat transfer coefficient over the entire length is 2
Answer:
i)ω=3600 rad/s
ii)V=7059.44 m/s
iii)F=1245.8 N
Explanation:
i)
We know that angular speed given as

We know that for one revolution
θ=2π
Given that time t= 2 hr
So
ω=θ/t
ω=2π/2 = π rad/hr
ω=3600 rad/s
ii)
Average speed V

Where M is the mass of earth.
R is the distance
G is the constant.
Now by putting the values


V=7059.44 m/s
iii)
We know that centripetal fore given as

Here given that m= 200 kg
R= 8000 km
so now by putting the values


F=1245.8 N
Answer: Power
Explanation:
The rate at which work is done or the amount of work done based on a period of time is referred to as power.
Power can also be defined as the amount of energy that is being transferred per unit time. The unit of power is one joule per second or simply called the watt.
