Answer:
The ratio that a material expands in accordance with changes in temperature is called the coefficient of thermal expansion. Because Fine Ceramics possess low coefficients of thermal expansion, their distortion values, with respect to changes in temperature, are low. The coefficients of thermal expansion depend on the bond strength between the atoms that make up the materials.

Explanation:
A NMOS is a n-channel MOSFET or Metal Oxide
Semiconductor Field Effect Transistor. This type
of transistor might be an enhancement or
depletion type nMOS transistor designed using
layers of Metal-oxide, Silicon-oxide and Silicon
fabricated on a substrate.
Answer:
6222.22 sec
Explanation:
Given data the power input to the refrigerator is 450 W
The COP of refrigerator is 1.5
Temperature 

mass of watermelon =10 kg
specific heat =4.2 KJ/kg°C
The amount of heat removed from 5 watermelon

We know that 

W=0.675 KW
so time required to cool the watermelon is
From the statement it is determined that the maximum limit is 100 and the lower limit is 0. At the same time there is an average of 85 that is closer to the upper limit than the lower limit, therefore the distribution will tend to occur to the left .
This will mean that people will begin to surround the average of 85 and that those who are 60, will be more than those who are below 50, and these 50 will be more than those who are by 40 and so on.
