1. The molecules of a gas are moving about freely. 2. Knowing the volume, the pressure, and the temperature of the gas, we can determine the state of its mass. 3. At the beginning of the century scientists succeeded in breaking the nucleus of the atom by attacking it with tiny particles flying with a great speed. 4. Being taken in proper proportion hydrogen and oxygen combine forming water. 5. The ammeter is a measuring device. 6. The forces acting between atoms within a molecule are very strong. 7. When speaking of water, we must remember that it is composed of tiny particles its molecules. 8. Having been detained by a snow storm, the liner was three days late. 9. I was told of their having been sent to the rescue operation. 10. He had good hopes of being sent to fulfilling this mission, and therefore, before returning home he spent some hours in preparing the plane for flight, trying it again and again.

1. Electroplating was invented in Russia, its inventor being Russian scientist Yacobi. 2. The bridge having been repaired, we were able to cross the river. 3. Electrons moving through a wire, electrical energy is generated. 4. The vapour pressure of a liquid becoming equal to atmospheric pressure, the liquid boils. 5. Water has a higher specific heat than most of other common substances, the specific heat of iron being approximately one-ninth the heat of water. 6. Any moving object is able to do work, the quantity of kinetic energy depending on its mass and velocity. 7. The temperature of a wire being raised, the random motion of the electrons increases. 8. The current flow having been changed, the direction of the magnetic lines of force also changed. 9. The substance being a dielectric, no current can flow through it. 10. Gases are light substances, the lightest of them being hydrogen.
