Question

A brass rod is 2m long at a certain temperature. Calculate the linear expansion of the rod for a temperature change of 100K (Take the linear expansivity of brass as 1.8 * 10^-5 K^-1.

Answer 1

Answer:

CHEMISTRY

A solution is defined as a:

A .

Homogeneous mixture of two or more substances

B .

Heterogeneous mixture of two or more substances

C .

Homogeneous mixture of liquid and solid components only

D .

Homogeneous mixture consisting of water as one of the components

A solution is a homogeneous mixture of two or more substances. A solution may exist in any phase. 

A solution consists of a solute and a solvent. 

The solute is the substance that is dissolved in the solvent.

For example, in a saline solution, salt is the solute dissolved in water as the solvent.

Answer 2

change in length = 1.8*10^5 × 100× 2
