What is the effect of temperature on dielectric constant of a dielectric?

Usually, dielectric materials have permanent dipoles. As temperature increases, the molecules in the dielectric have more thermal energy and therefore, the amplitude of random motion is greater. This means that the molecules are less closely aligned with each other (even in the presence of an electric field). Hence, the dielectric constant reduces.

Dielectric constant of insulator depends on?
Frequency of alternating field applied & temperature
Which dielectric in this world has highest dielectric constant?
Strontium Titanate has a dielectric constant of 233. TDK in Japan makes Ultra-high Voltage Ceramic Capacitors using this as the dielectric material. Compared to distilled water at 76.7 - 78.2 (lowers as temperature rises). Types of glass can vary between 4 and 10.
Is dielectric strength the same as dielectric constant?
No, these are two unrelated properties of a material.
What are the factor affecting capacitances of capacitance?
The area of the sheets, the distance between them, and the material between them.
Can the dielectric constant of carbon in water be measured?
dielectric constant is a property of a material, this question is asking the property of a two mixed together, in an undeclared ratio. But yes dielectric constants can be measured. The problem you will have is keeping a uniform mix.
Why does dielectric constant decrease with an increase in temperature?
If the temperature increases, the conductivity will increase too which means the dielectric constant is reduced
What is dielectric constant in chemical terms?
dielectric constant
Dielectric constant of insulator depends on?
Frequency of alternating field applied & temperature
What is the sodium hypochlorite dielectric constant?
dielectric constant for sodium Hypochlorite

Dielectric constant of metal is?
The dielectric constant varies, depending on the material.
Why dielectric constant of polyethylene is independent of temperature?
it is a polymer in which their is no induction effect and no dipoles are formed within the molecules as all the bonds are of equal strength and therefore no polymerization occurs in contrast to molecules such as pvc
How water is dielectric constant?
The dielectric constant of water varies with temperature and is approximated by this polynomial equation: E = 87.740 - 0.40008*t + 9.398*(10^-4)*t^2 - 1.410*(10^-6)*t^3
What is the effect of dielectric constant of water on the solubility of the ionic salt?
Water has a very high dielectric constant so when an ionic salt is placed in water it ionizes and water molecules react with ions of solute and make a solution
What is relative permittivity if dielectric constant of water is 80.10?
'Dielectric constant' is an archaic term for relative permittivity. They are one and the same.
Is dielectric strength the same as dielectric constant?
No, these are two unrelated properties of a material.
What is the dielectric constant of Silver?
infinite
