Does cubical Expansivity depends on original volume? The ratio of ∆V/V is same in each case for a solid so, the coefficient of cubical expansion is same for all volume of a solid and

does not depend on the volume

. The unit of this expansivity is per kelvin (K

– 1

).

Does the coefficient of cubical expansion depends on original length?

Substance α (ppm) Silica (fused) 0° to 100°C 0.50

How does the cubical expansion of solids depend on the original length of the solid?

Explanation: Linear Expansion of solids: When a metal rod is heated, its length increases (it expands).

The increase in length depends on the original length of the rod, the rise in temperature, and the nature of the material of the rod

.

What is linear Expansivity does it depends on original length?

What are the factors that affect the cubical expansion of a liquid?

Water expands when frozen into ice. Its volume is increased thus lowering its density from 1.00 gram per milliliter to 0.92 gram per milliliter.

Temperature is the factor affecting the cubical expansion of water.

Does the value of coefficient of superficial expansion of solid depends upon its original area?

Relation Between α and β:

Let l, b and A be the length, breadth, and area of the plate at temperature t °C. Consider superficial expansion of the plate area. Thus

the coefficient of superficial expansion is twice the coefficient of linear expansion

.

What is the coefficient of cubical expansion?

The coefficient of cubical expansion is defined as

the ratio of increase in the volume of a solid per degree in the rise of temperature to its initial volume

.

On what factors does the cubical expansion of solids depend?

Thermal expansion of solids depends, on the following factors : (i)

nature of the material, (ii) initial dimension of the solid, (iii) rise in temperature of the solid

.

What is cubical expansion of solid?

Coefficient of cubical expansion; It is defined as

the increase in volume per unit volume per degree in temperature

.

What is the difference between superficial expansion and cubical expansion?

If there is an increase in the volume of a solid body due to heating, it is called cubical expansion. If there is an increase in the area of a solid object due to heating, then the expansion is called superficial expansion.

What does linear expansion depend?

Linear expansion of a substance depends upon

the original length, change in temperature and nature of the material

.

What is meant by coefficient of linear and cubical expansion?

Coefficient of cubical expansion is

the fraction of volume increased when a body is heated

. Its the property of the material. γ=(ΔV/V)/ΔT. Unit of γ is OC−1.

What is meant by coefficient of linear expansion and coefficient of cubical expansion derive relationship between them?

Consider the cubical expansion of the solid.

V=Vo(1+γt) From (1) and (2), γ=3α

Hence, the relation between the coefficient of linear and cubical expansion is derived.

Which of the following factors does thermal expansion doesn’t depend?

statement (1): The linear expansion does not depend on

the nature of the material, initial length, and rise in temperature

.

On what factors the linear expansion of a metal rod depends?

As the temperature of a material increases, it begins to expand. For instance, a metal rod or beam will increase its length by an amount ∆L. The value of ∆L depends on

the original length (Lo) at the original temperature (To), the temperature to which it is heated (T) and the coefficient of linear expansion (α)

.

What are the factors on which increase in area of a metal plate on heating depends upon?

THREE FACTORS ARE:

(i)

Original area of plate A0. (ii) Rise in temperature t. (iii) Nature of material of plate

.

Can the cubical Expansivity be derived from this value?

Can the cubical expansivity be derived from this value? Ans:

The coefficient of linear expansion of given solid can be determined by using pullinger’s apparatus

. It consists of a rod of about 50cm in length whose coefficient of linear expansion is to be determined.

How does superficial expansion of solids depends on the nature of the metal?

How is cubical expansion calculated?

How does the coefficient of cubical expansion of a substance vary with temperature?

it is yes. Explanation:Does cubical expansivity depend upon initial volume of solid? … Because we know cubical expansivity is equal to

rise in increase in volume per unit initial volume per unit rise in temperature

, where ratio of increase in volume and initial volume is constant.

Which liquid has the highest coefficient of cubical expansion?

Answer:

Air

has highest cubical expansion then solid and liquid.

What is cubical expansion of liquid?

Liquid has only volume. When heated, its volume increases.

Increase in volume

is called cubical expansion.

What are the three factors of linear expansion?

Does coefficient of linear expansion depends on temperature?

The coefficient of linear expansion is

independent of temperature difference

, length of material, and shape of the material. So option 4 is correct.

Is area expansion and superficial expansion same?

Area or superficial Expansion:

Superficial expansion is defined as the increase in surface area of the solid on heating

. If you consider at 0

0

C area of a solid is A

0

then its area at t

0

c is given by: A

0

(l+βt). Unit of β is

0

C

– 1

or K

– 1

. Where β is known as the coefficient of superficial expansion.

What will be the ratio of coefficient of volume expansion of two cubical containers?

Answer. Answer: The ratio of coefficient of apparent expansions of the same liquid in two different vessels is

1:2

.

How are three coefficients of expansion related to each other?

What is coefficient of linear Expansivity?

Coefficient of Linear Expansion is

the rate of change of unit length per unit degree change in temperature

. The coefficient of linear expansion can be mathematically written as: α L = d L d T.

What is the relation between the linear and the volumetric coefficients of thermal expansion?

How is the coefficient of volume expansion β related to the coefficient of linear expansion α?

What are the three factors on which this change in length depends?

Change in length is related to

original length, the type of material and the amount of temperature change

.

On what factors does the rise of temperature of any portion of the rod depends in variable state?

What is the difference between real and apparent expansion?

If the liquid is heated directly without using any container then the expansion that you observe is termed as a real expansion of the liquid. The expansion of the liquid apparently observed without considering the expansion of the container is called the apparent expansion of the liquid.

On what factors does the coefficient of thermal expansion depend?

The amount by which it expands depends on three factors:

its original length, the temperature change, and the thermal (heat) properties of the metal itself

.

Does the coefficient of linear thermal expansion change if we change the length of the rod?

question. Answer :

No, Coefficient of linear expansion does not depend on length

.
