What is the ratio (in the form of a decimal) of the root-mean-square speed of 238UF6 to that of 235UF6 at constant temperature?
NNADVOKAT [17]

Answer:

ratio=0.996m/s

Explanation:

RMS=\sqrt{\frac{3RT}{M} }; M= molecular weight of compound;

RMS speed is inversly proportional to the molecular weight hence compound having less molecular weight will have more rms speed value.

V1 for 238 UF_{6}; M1=238+114=352g/mole

V1 for 235 UF_{6}; M1=238+114=352g/mole

V1=\sqrt{\frac{3RT}{352} };

V2=\sqrt{\frac{3RT}{349} };

\frac{V1}{V2}=ratio of 238UF_{6} F6 to 235UF_{6}=\sqrt{\frac{349}{352} };

\frac{V1}{V2} =0.9957m/s;

\frac{V1}{V2} =0.996m/s;

Which of the following statements correctly explains the motion of atoms and molecules within the different states of matter? *
sineoko [7]

Answer:

The correct answer is : The particles within all three states of matter are constantly moving.

Explanation:

The particles in the solid, liquid and gaseous states are in motion. In the latter is where they present greater movement and high kinetic energy, then follow the liquid state and finally the solid where the movement is more restricted (in this case, the particles vibrate).
