Which defines the average kinetic energy of a system's particles?
ch4aika [34]
<h2>Answer:Temperature</h2>

Explanation:

Average kinetic energy of a system of particles is given by \frac{f}{2} kT.

where,

f is the number of degrees of freedom of the particles.

k is the boltzmann constant.

T is the temperature.

For general gases,

f=3

For a given degrees of freedom,average kinetic energy is directly proportional to temperature.

So,the average kinetic energy depends on temperature.

A 30.7 mL, 1.66 M KMnO4 solution is mixed with 16.7 mL of 0.704 M KMnO4 solution. Calculate the concentration of the final solut
motikmotik
Ma = 1.66 M

Va = 30.7 mL

Mb = 0.704 M

Vb = 16.7 mL

Using the law <span>of dilution :
</span>
Mf = Ma x Va + Mb x Vb / Va + Vb

Mf = 1.66 x 30.7 +  0.704 x 16.7 / 30.7 + 16.7

Mf = 50.962 + 11.7568 / 47.4

Mf = 62.7188 / 47.4

Mf = 1.323 M

hope this helps!
