Concept explainers
(a)
Interpretation: The questions based on the results of J.J. Thomson’s cathode ray experiment are to be answered.
Concept introduction: Cathode rays are considered to be made up of negatively charged particles. These negatively charged particles were termed as “corpuscles” by J.J. Thomson.
To determine: The name by which corpuscles are known now-a-days.
(b)
To determine: The reason as to why the beam deflected when passed between electrically charged plates.
(c)
To determine: The explanation corresponding to the change in the position of the spot on the phosphorescent screen if the polarity of plates was switched.
(d)
To determine: The effect of reduction in voltage on the position of spot on the phosphorescent screen.

- Please correct answer and don't used hand raitingarrow_forwardThe vibrational contribution isa) temperature independent for internal energy and heat capacityb) temperature dependent for internal energy and heat capacityc) temperature independent for heat capacityd) temperature independent for internal energyarrow_forwardQuantum mechanics. Explain the basis of approximating the summation to an integral in translational motion.arrow_forward
- Quantum mechanics. In translational motion, the summation is replaced by an integral when evaluating the partition function. This is correct becausea) the spacing of the translational energy levels is very small compared to the product kTb) the spacing of the translational energy levels is comparable to the product kTc) the spacing of the translational energy levels is very large compared to the product kTarrow_forwardDon't used Ai solutionarrow_forwardPlease correct answer and don't used hand raiting don't used Ai solutionarrow_forward

- The table includes macrostates characterized by 4 energy levels (&) that are equally spaced but with different degrees of occupation. a) Calculate the energy of all the macrostates (in joules). See if they all have the same energy and number of particles. b) Calculate the macrostate that is most likely to exist. For this macrostate, show that the population of the levels is consistent with the Boltzmann distribution. macrostate 1 macrostate 2 macrostate 3 ε/k (K) Populations Populations Populations 300 5 3 4 200 7 9 8 100 15 17 16 0 33 31 32 DATO: k = 1,38×10-23 J K-1arrow_forwardDon't used Ai solutionarrow_forwardIn an experiment, the viscosity of water was measured at different temperatures and the table was constructed from the data obtained. a) Calculate the activation energy of viscous flow (kJ/mol). b) Calculate the viscosity at 30°C.
