Marcet Boiler 1. Abstract This experiment was carried out to determine the relationship between the pressure andthe temperature of saturated steam in equilibrium. Besides that this experiment was alsodone to demonstrate the vapor pressure curve. The market Boiler was used for thisexperiment. When the pressure increases‚ the temperature also increases. Therefore‚ therelationship of pressure and temperature is directly proportional. The derived formulaeand the data were used to calculate the slope

Boyle’s law‚ Pascal’s law‚ and Archimedes’ law. Boyle’s Law states that under conditions of constant temperature and quantity‚ there is an inverse relationship between the volume and pressure for an ideal gas. Pascal’s Law states that if pressure is applied to a non-flowing fluid in a container‚ then that pressure is transmitted equally in all directions within the container. Archimedes’ principles is an upward force on an object immersed in a fluid (a liquid or a gas)‚ enabling it to float or

The class measured the pressure in the test tube during the reaction of the substance with‚ 1.5 ml of H2O2‚ 1.5ml of H2O and different amounts of enzyme drops‚ to determine how much oxygen gas is produced during the reaction since the pressure of the test tube will get higher as more oxygen gas is accumulated during the reaction. 2) If more drops of the enzyme are added to the

Relationship Between Pressure‚ Temperature‚ and Volume The relationships between temperature and volume is directly proportional. This means that volume expands as temperature rises. A drop in temperature can also mean a drop in volume. In the 18th century‚ scientists discovered that relationships between pressure‚ volume‚ and temperature were constant across types of gas. These early laws gave rise to the combined gas laws and the ideal gas laws. Charles’s Law Charles’ Law shows a direct relationship

Boyle’s law states that‚ “The difference in pressure caused by changes in lung volume force air into our lungs when we inhale and out when we exhale.” Pg.748 if volume increases‚ outside pressure must decrease. This process involves the diaphragm muscle which increases‚ during forceful inhalations expanding the
