## How the age of mummies , dead bodies and fossils is calculated?

The aging of different organisms is mainly calculated by the special technique called the Radiocarbon dating. In this technique the age of any specimen is calculated on the basis of the present amount of an isotope of a particular element. Isotopes are the atoms of an element that have same atomic number but different atomicContinue reading “How the age of mummies , dead bodies and fossils is calculated?”

## What will be the volume of water when it is heated from 0 degrees Celsius to 10 degrees Celsius?

According to CHARLES LAW “At constant pressure, The volume of a given mass of a gas increases or decreses by 1/273 of its volume at 0 ͦ  degree C for every one degree centigrade rise or fall in temperature”. Vol at 10 = vol at zero + 10 x vol at zero/273
