The atmosphere is made of a variety of gases, roughly in the following proportions:. 78% Nitrogen. 20% Oxygen. 1% Argon. <1% Carbon Dioxide. <1% Water vapor. Air temperature. This is the average speed or kinetic energy of all the particles in a mass of air.. Ahhhh. …. You’ve been soaking in the tub to try and relax after a hard day of standardized testing at school. Getting out of the tub, you notice that your fingertips and toes are like little raisins. Have you just aged 60 years?!?! No way, that’s just osmosis in action! Your fingers have absorbed the bath water, causing the tips to form wrinkly folds. . Objective. : To understand how cells transport materials. SQOD. : . Why does the size of a cell play such an important role in the movement of materials throughout the cell?. The larger the cell, the more time it takes to deliver the necessary materials to the various organelles. Smaller cells move materials much more quickly and efficiently.. What is pressure?. Pressure is the force per unit area that is applied on the surface of an object.. Chapter 12: Forces and Fluids. Calculating pressure. Pressure increases if the force applied increases and decreases if the area of contact increases.. Viscosity is how engineers measure the resistance of fluids when being . deformed:. τ. = . μ. (du/dy. ). The less viscous the fluid, the greater its ease of . movement.. Viscosity is useful for calculating the force needed to move a fluid. For example, in these industries: .  Fluid Statics. Why things float .  . Archimedes’ Principle. . Fluids in Motion .  . Fluid Dynamics. Hydrodynamics. Aerodynamics. 1. Example. : What does 1 liter (about a quart) of water weigh?. Daniel Bernoulli was a Swiss scientist (1700-1782) who analyzed the pressures involved with fluids.. He found that stationary fluids such as air and water exert pressure in all directions.. When a fluid is moving slowly it has a higher pressure or more force; when that same fluid is moving faster it has lower pressure or less force.. The body is nearly two-thirds water, so it is important to consume enough fluid to stay hydrated. If we do not consume enough water, we become dehydrated.. Water. Our bodies lose water all the time, when we go to the toilet, from sweat and also through respiration. We need to replace this water by drinking regularly to prevent dehydration.. lean. - . 70% of Body wt. is water. Fatty animals – Less body Water – As low As 40%. TOTAL BODY WATER.
