order to accommodate this rise in oxygen demand there must be an increase in the subject’s minute ventilation. The rise in minute volume‚ with exercise‚ could be accomplished by increasing the volume of each breath‚ the tidal volume‚ increasing the respiratory rate or by some combination of the two. In the subject’s case it was a combination of the two. Tidal volume is more effective at increasing minute ventilation than respiratory rate‚ however‚ if a subject is unfit they will be required to increase

about boiling water. If you cover the tin and allow the water and air to cool down‚ the air will cool and contract‚ lowering the pressure in the tin. If it lowers enough‚ the partial vacuum will collapse the walls of the can! The boiling point definitely reduces with air pressure. There is a famous demonstration where boiling water or coffee is drunk‚ the trick is it was in a vacuum chamber where it boiled at room temperature. The actual definition of the boiling point of water is the temperature

Properties of Water Introduction: Water’s chemical description is H2O. As the diagram to the left shows‚ that is one atom of oxygen bound to two atoms of hydrogen. The hydrogen atoms are "attached" to one side of the oxygen atom‚ resulting in a water molecule having a positive charge on the side where the hydrogen atoms are and a negative charge on the other side‚ where the oxygen atom is. This uneven distribution of charge is called polarity. Since opposite electrical charges attract‚ water molecules

How water is purified in water treatment plants Pre-treatment 1. Pumping and containment – The majority of water must be pumped from its source or directed into pipes or holding tanks. To avoid adding contaminants to the water‚ this physical infrastructure must be made from appropriate materials and constructed so that accidental contamination does not occur. 2. Screening (see also screen filter) – The first step in purifying surface water is to remove large debris such as sticks‚ leaves

SALT WATER Introduction: Salt water refers to water that contains dissolved salts‚ known as saline water or seawater‚ water from oceans or seas. It is a home to varieties of aquatic animals‚ for example‚ fishes and snails. Some of these animals find it difficult to live in fresh water. If salt water animals go to live in fresh water they can not adapt the environment led to die to them. This essay aims to discuss the importance of salt water and the sub- types namely ocean‚ sea‚ and coral reefs
