Question

What is the ratio of find volume to initial volume if gas is compressed adiabatically till it's temperature is doubled.?

Explain Mendeleev's period law in detail..

Answer 1

=》The ratio will be less than 1/2.

●The word periodic means occurring or repeating at intervals. So the periodic law states that the chemical properties of the elements occur periodically when the elements are arranged in order of increasing atomic mass. For example, if you go down a family(column) of elements, then those elements will have similar chemical properties because the chemical properties are repeating at intervals
Hope this helps!

Answer 2

Answer:

Explanation:

Mendeleev's period law states that the the physical and chemical properties of all elements are a periodic function of their atomic weights.

This theory was later proved wrong by HGJ Moseley, who on doing analysis by X-ray,plotted a graph and showed that atomic number is the primary factor which determines physical and chemical properties of elements
