To analyze the expected results of repeating the alpha particle scattering experiment using a thin sheet of solid hydrogen instead of gold foil, we can follow these steps:
### Step 1: Understand the Original Experiment
The original alpha particle scattering experiment, conducted by Ernest Rutherford, involved firing alpha particles at a thin gold foil. The results showed that while most alpha particles passed through the foil, a small fraction were deflected at large angles, indicating the presence of a small, dense nucleus within the atom.
### Step 2: Consider the Properties of Solid Hydrogen
Solid hydrogen consists of hydrogen atoms, which have a single proton in their nucleus and are much lighter than gold atoms. The atomic mass of hydrogen is approximately 1 u (atomic mass unit), while that of gold is about 197 u. This significant difference in mass will affect the scattering interactions.

Raghav is a student of class X who was trying to convert the groundnut oil into solid fat (vanaspati ghee). He took the oil inan appropriate flask having an arrangement for passing hydrogen gas into it. Raghav pased the hydrogen gas into oil and heated them together for a considerable time. On cooling the apparatus, Raghav found that even after heating them together for a considerable time. On cooling the apparatus, Raghav found that even after heating together oil and hydrogen for a considerable time, no solid fat was formed. Raghav shard this problem with his sister Divya who is studyging in class XI. She advised him ot add a certain finely divided substance while heating oil wih hydrogen gas. When Raghav repeated the experiment by adding this substance to oil and hydrogen mixture, then the liquid oil was converted into a solid fat.Divya advised Raghav not to consume the fat prepared by him in the laboratory. (a) What was he finely divided substance which Raghav was asked to add for converting oil into fat? What is its function? (b) What type of substance is (i) an oil, and (ii) a fat? (c) What is the special name of conversion of oils into fats used in Industry? (d) What are the two types of chemical reactions exemplified by the conversion of oils into fats? (e) Why did Divya ask Raghav not to consume the fat prepared by him in the laboratory? (f) What values are exhibited by Divya in this episode?
Answer the following questions, which help you understand the difference between Thomson’s model and Rutherford’s model better. (a) Is the average angle of deflection of -particles by a thin gold foil predicted by Thomson’s model much less, about the same, or much greater than that predicted by Rutherford’s model? (b) Is the probability of backward scattering (i.e., scattering of alpha -particles at angles greater than 90° ) predicted by Thomson’s model much less, about the same, or much greater than that predicted by Rutherford’s model? (c) Keeping other factors fixed, it is found experimentally that for small thickness t, the number of alpha -particles scattered at moderate angles is proportional to t. What clue does this linear dependence on t provide? (d) In which model is it completely wrong to ignore multiple scattering for the calculation of average angle of scattering of alpha -particles by a thin foil?
In this sectin each item consists of six sentences of a passage. The first and sixth sentences are given in the beginning as S1 and S6. The middle four sentences in each have been jumbled up and labelled as P, Q, R and S. You are required to find the proper sequence of the four sentences and mark your response accordingly on the Answer Sheet. S1 : On increasing the temperature of solids, the kinetic energy of the particles increases. S6 : The temperature at which a solid melts to become a liquid at the atmospheric pressure is called its melting point. P : A stage is reached when the solid melts and is converted to a liquid. Q : Due to the increase in kinetic energy, the particles start vibrating with greater speed. R : The particles leave their fixed positions and start moving more freely. S : The energy supplied by heat overcomes the forces of attraction between the particles. The correct sequence should be
