What does the kinetic theory state about the relationship between the speed and temperature of gas molecules?
1 answer:
As the temperature increases, the speed of gas molecules increases
The kinetic theory state about the relationship between the speed and temperature of gas molecules as with an increase in temperature, the speed of gas molecules increases.
The energy that an object possesses as a result of its motion is known as kinetic energy.
The average of the kinetic energies of all the particles in a system is known as the average kinetic energy.
The following equation provides the answer:
K =
K= kinetic energy
R= gas constant
T= temperature
- It is clear from above that kinetic energy and system temperature are inversely correlated.
- Therefore, if the temperature is higher, the system's average kinetic energy will also be higher, increasing the speed of the molecules.
<h3>What does kinetic theory state?</h3>

Answer:
Explanation:
Given:
Pressure = 745 mm Hg
Also, P (mm Hg) = P (atm) / 760
Pressure = 745 / 760 = 0.9803 atm
Temperature = 19 °C
The conversion of T( °C) to T(K) is shown below:
T(K) = T( °C) + 273.15
So,
T₁ = (19 + 273.15) K = 292.15 K
Volume = 0.200 L
Using ideal gas equation as:
where,
P is the pressure
V is the volume
n is the number of moles
T is the temperature
R is Gas constant having value = 0.0821 L.atm/K.mol
Applying the equation as:
0.9803 atm × 0.200 L = n × 0.0821 L.atm/K.mol × 292.15 K
⇒n = 0.008174 moles
From the reaction shown below:-
1 mole of react with 2 moles of
0.008174 mole of react with 2*0.008174 moles of
Moles of = 0.016348 moles
Volume = 13.4 mL = 0.0134 L ( 1 mL = 0.001 L)
So,
