The rapid, irregular motions of these particles caused by collisions with air molecules can be observed with a microscope. Assume a particular type of smoke particle has a mass of 3.00 x10^-16 kg and is in a room with a temperature of 300 K. a) if instead you were considering a hydrogen gas molecule (m= 3.34x10^-26 kg) at 300 K, would the average translational kinetic energy be larger than, smaller than or equal to that of the smoke particle? b) would the rms speed of the hydrogen atom be larger than, smaller than, or equal to that of the smoke particle?Use the kinetic molecular theory to explain what happens at the particle level in the situation below.A woman places several moth balls in a ziplock bag and seals the bag.

- a)Set the temperature to 350 Kelvins (350 K) and select atomic hydrogen (A = 1) for gas type. What is the likeliest particle speed (in m/s) to be found in a sample of atomic hydrogen at 350 K? Double-check that you have set the temperature to 350 K. Have you selected atomic hydrogen (A = 1) from the drop-down menu? Are you reading the speed value from the center of the graph? m/s (b) Now double the particle mass, by selecting molecular hydrogen (A = 2) while leaving the temperature unchanged. What is the new value of vmax (in m/s)? Double-check that you have set the temperature to 350 K. Have you selected molecular hydrogen (A = 2) from the drop-down menu? Are you reading the speed value from the center of the graph? m/s (d) The kinetic energy of an atom or molecule is proportional to the particle's mass and to the square of its speed KE = 1/2 mv2. Suppose that m = 1 amu for atomic hydrogen (H) and m = 2 amu for molecular hydrogen (H2). Using the vmax value you…Let's say you blew three baloons to the same size and left one baloon at room temperature, and kept one baloon in an ice bath, and one baloon above a hot water container. You left the laboratory for 30 minutes and when you came back, you saw that the size of the baloon in the ice bath was smaller than before and size of the baloon above hot water container was larger than the original size. As chemistry student, how do you explain the reason for this observation.The density of the distribution of the speed of motion of a molecule along the positive X axis has the form p(s) = 4*squreroot(a3/pi)*s2exp(-as2) (The constant a is determined by the temperature of the gas and the mass of the particle observed; a = m/ (2kT), wherek is the Boltzmann constant)• Find the mean distance traversed by the molecule in a unit of time.• Find the mean value of the kinetic energy of the molecule.
