When two rods of the same length and material are heated to different temperature the rod is heated to a higher temperature more than the other rod?

When two rods of the same length and material are heated to different temperature the rod is heated to a higher temperature more than the other rod?

Which rod will expand more? Solution: Two rods with the same length and material are heated to different temperatures. Rod with higher temperature i.e 10°C will expand more.

Does the linear Expansivity depend on length?

Expansion of Solids The increase in length of any side of a solid will depend on the original length l0, the rise in temperature t, and the coefficient of linear expansion α. The value of the coefficient of expansion varies from substance to substance.

Does the linear expansivity of metal depend on initial length?

statement (1): The linear expansion does not depend on the nature of the material, initial length, and rise in temperature.

Why a longer rod expands more than a shorter rod on being heated to the same temperature?

A longer rod expands more than a shorter rod on being heated to the same temperature because the intermolecular distance increases by same amount in both of them. Therefore, greater expansion is seen in longer rod.

Which rod expands less when heated to the same temperature?

the iron rod will expand less.

What change is found in the length of a rod when it is heated?

linear expansion
The increase in length of iron rod on heating is called linear expansion.

When rod is heated its linear expansion depends on?

(b): The linear expansion depends upon the initial length of the rod only.

Why change in length depends on original length of material and change in temperature?

The length of an object is one of the more obvious things that depends on temperature. When something is heated or cooled, its length changes by an amount proportional to the original length and the change in temperature: The coefficient of linear expansion depends only on the material an object is made from.

What is the initial length?

Initial length, abbreviated as li, is the length before linear thermal expansion.

What is the relation between linear superficial and cubical Expansivity?

When a substance in the form of a rod or a wire is heated, its length increases. Such expansion is called linear expansion. The expansion in area of an object with rise in temperature is called superficial expansion. The expansion in volume of an object with rise in temperature is called cubical expansion.

Does alcohol expand more than water?

water expands more than alcohol.

Which of the following expands the most for the same rise in temperature?

For a given rise in temperature, gases expand much more and faster than liquids. This is due to the fact that gases have more interatomic or intermolecular space than liquids. Among the given, helium is a gas while the rest are liquids: Helium expands more than the rest.

What happens when two copper rods of the same length are given?

Two copper rods of same length, but of different diameters of cross section are given same amount of heat. Assuming no heat losses. The mass of thin rod is less than thick rod, so the rise in the temperature will be higher for thin rod. ΔL = LαΔT . So the rise will be more for higher ΔT. Thin rod will expand more.

What is the specific heat of aluminum in JG?

Comparing Specific Heats of Metals. Two different metals, aluminum and lead, of equal mass are heated to the same temperature in a boiling water bath. The specific heat capacities of each metal is displayed to students: Al 0.903 J/g°C Pb 0.160 J/g°C.

Why does thin rod expand more than thick rod?

The mass of thin rod is less than thick rod, so the rise in the temperature will be higher for thin rod. ΔL = LαΔT . So the rise will be more for higher ΔT. Thin rod will expand more. Was this answer helpful?

What is the specific heat capacity of aluminum and lead?

Two different metals, aluminum and lead, of equal mass are heated to the same temperature in a boiling water bath. The specific heat capacities of each metal is displayed to students: Al 0.903 J/g°C Pb 0.160 J/g°C. The metals are added to two insulated cups or calorimeters, each containing the same amount of water initially at room temperature.
