Answer is "B - 700,000".
Kinetic energy of a single particle (atom or molecule) is directly proportional to its
temperature according to the following equation.
KE = (3kT)/2
Where KE is the
kinetic energy of a single atom/molecule (J), k is the Boltzmann
constant (1.381 × 10⁻²³ J/K) and T is the temperature (K)
When temperature increases, then the kinetic
energy increases.
If kinetic
energy of atoms increases, then there will be more motions which create many
collisions.
Answer: The correct answer is Option B.
Explanation:
Collision is defines as the interaction of two bodies in motion. It depends on the kinetic energy of the particles. Number of collisions increases as kinetic energy of the particles increases.
Kinetic energy is the measure of temperature of the system. It is given by the equation:
[tex]E=\frac{3}{2}kT[/tex]
where,
E = kinetic energy of the particles
k = Boltzmann constant
T = temperature
We are given:
Number of collisions at 273 K = 250,000
We need to find the number of collisions at 350 K. As, the number of collisions increases as we increase the temperature. So, from the given options, the collisions at 350 K will be 700,000.
Hence, the correct answer is Option B.
