Water decomposes to O<sub>2</sub> and H<sub>2</sub> under suitable conditions as represented by the equation below: 2H<sub>2</sub>O 2H<sub>2</sub> + O<sub>2</sub> (a) If 2500 cm<sup>3</sup> of H<sub>2</sub> is produced, what volume of O<sub>2</sub> is liberated at the same time and under the same conditions of temperature and pressure? (b) The 2500 cm<sup>3</sup> of H<sub>2</sub> is subjected to times increase in pressure (temp. remaining constant). What volume will H<sub>2</sub> now occupy? (c) Taking the value of H<sub>2</sub> calculated in 5(b), what changes must be made in Kelvin (absolute) temperature to return the volume to 2500 cm<sup>3</sup> pressure remaining constant.
