A sample of a gas has a volume if 852mL at 288K. What temperature did s necessary for the gas to have a volume of 945mL?
asambeis [7]

Answer:

The answer to your question is T2 = 319.4°K  

Explanation:

Data

Volume 1 = V1 = 852 ml

Temperature 1 = T1 = 288°K

Volume 2 = V2 = 945 ml

Temperature 2 = T2 = ?

Process

To solve this problem, use Charles' law.

            V1/T1 = V2/T2

-Solve for T2

            T2 = V2T1/V1

-Substitution

            T2 = (945 x 288) / 852

-Simplification

            T2 = 272160 / 852

-Result

            T2 = 319.4°K

How does atomic radius change from top to bottom in a group in the periodic table?
suter [353]
The atomic radius increases as you would go down a particular group on the periodic table of elements. This is because along with a greater number of protons, there would also be electrons as well, and thus the need of electron shells surrounding the atom would also be required, to compensate for the more electrons, as according to the bohr model, each shell contains 8 electrons in its electron shell. Thus the distance from the nucleus to the outermost shell increases, the atomic radius.
