1. Atomic nuclei can interact with neutrons, electrons, and gamma radiation. 2. As we should infer from the vigour with which its constituents combine, water is a very stable substance. 3. The current can flow through a wire only when the circuit is closed. 4. The magnitude of electrical current may vary from a minute amount to a very large quantity. 5. In the ammeter the current which is to be measured flows between terminals A and B. 6. Speaking about the structure of the atom one should remember that the proton is smaller but heavier than the electron. 7. Only very little current should flow through the voltmeter to operate it, and its mechanism must be very delicate and fine. 8. To tear away from the liquid the molecule which leaves it should have a large amount of kinetic energy. 9. Elastic limit is the point beyond which one should not attempt deforming the body if it is to return to its original condition. 10. The convocation of international scientific conferences, which are to be attended by scientists from different countries and belonging to different schools, can undoubtedly promote the development of science. 11. The investment in an atomic reactor must be high, but the running cost is so low that something like a large tanker can be run as cheaply on atomic energy as on conventional fuel. 12. Working with picric acid one must remember of its explosive nature. 13. Our scientists had to solve the problem of controlling chain reactions. 14. The nature of the raw material must be taken into consideration in the selection of a method of its analysis. 16. A voltmeter may be connected between any two points whose voltage difference is to be measured. 17. You ought to know the properties of the ingredients. 18. There must be a greater number of turns of wire on the field magnets to produce a magnetic field of adequate strength. 19. If “water gas” is to be used as a source of pure hydrogen, carbon monoxide must be removed. 20. One must remember that any reaction is theoretically reversible. 21. It we are to convert a gas into a liquid, we must increase the attraction of the molecules for one another. 22. The unit of heat should not be confused with the degree of temperature. 23. This explosive may be either a liquid or a solid.
