In alloys consituent metals retain their ______ properties .

Consider the following statements and which among them are correct? A. Compounds are formed by two or more elements in a definite proportion. B. Mixtures do not have any fixed proportion of component in it. C. Alloys are made up of combination of metals only. D. Mixture and alloys retain the property of its constituent elements.

Alloys are prepared by mixing a metal with other metals or nonmetals in certain proportion. The properties of the main metal change when the metal is alloyed. i. How do the properties of iron change when carbon and chromium are mixed with it? ii. How do the properties of copper change when tin is mixed with it?

In honey, the main consituent is

If the resistivity of an alloy is rho' and that of consituent metals is 'rho' then

One of the consituents of German silver is

Physical properties of metals and non-metals|Chemical properties of metals|Metals with non-metals|Occurrence of metals|Corrosion|Summary

Assertion (A): Alloys are commonly used in electrical heating devices like electric iron and heater. Reason (R): Resistivity of an alloy is generally higher than that of its constituent metals but the alloys have low melting points then their constituent metals.
