Read the following text and answer the following questions on the basis of the same: The term sexually transmitted disease (STD) is applied to the group of diseases that spread by sexual contact. Some infections like hepatitis-B and HIV can spread by sharing injection needles, surgical instruments etc. Except for hepatitis B, HIV infections, genital herpes, most of the STDs are completely curable if detected early and treated properly. Though all persons are vulnerable to these infections, their incidences are high in the age group of 15-24 years. AIDS is caused by HIV. HIV is transmitted through:

The constant motion and high velocities of gas particles lead to some important practical consquences. One such consquences is that gases mix rapidly when they come in contact. Take the stopper off a bottle of perfume, for instance, and the odour will spread rapidly through the room as perfume molecules mix with the molecules in the air. This mixing of different gases by random molecular motion and with frequent collision is called diffusion. A similar process in which gas molecules escape without collision through a tiny hole into a vacuum is called effusion. Both the processes follow Graham's law which is mathematically put as r prop sqrt(1//d) . The average distance travelled by molecules between successive collisions is called mean free path. Answer the following questions on the basis of the above information: X mL H_(2) effuses through a hole in a container in 5 s . The time taken for the effusion of the same volume of the gas specified below under identical conditions is
