(a) What is the mass of a deep breath of air having a volume of 2.00 $\mathrm{L}$ ? (b) Discuss the effect taking such a breath has on your body's volume and density.

(a) $m_{A}=2.58 \times 10^{-3} \mathrm{kg}$(b) Volume increases and density decreases.

Suppose you have a coffee mug with a circular cross section and vertical sides (uniform radius). What is its inside radius if it holds 375 g of coffee when filled to a depth of 7.50 cm? Assume coffee has the same density as water.

What depth of mercury creates a pressure of 1.00 atm?

In physics, a fluid is a substance that continually deforms (flows) under an applied shear stress. Fluids are a subset of the phases of matter and include liquids, gases, plasmas and, to some extent, plastic solids.

A fluid is a substance that continually deforms (flows) under an applied shear stress. Fluids are a subset of the phases of matter and include liquids, gases and plasmas. Fluids display properties such as flow, pressure, and tension, which can be described with a fluid model. For example, liquids form a surface which exerts a force on other objects in contact with it, and is the basis for the forces of capillarity and cohesion. Fluids are a continuum (or "continuous" in some sense) which means that they cannot be strictly separated into separate pieces. However, there are theoretical limits to the divisibility of fluids. Fluids are in contrast to solids, which are able to sustain a shear stress with no tendency to continue deforming.

West. What the massive a deep breath of air having a volume of to leaders is no. First, we give her get leaders into Centimeters Cube. So two leaders is 2000 milliliters and one middle leader is one cubic centimeters. So we got 2000 cubic centimeters. Is there volume? You can look up the density of air, which is 1.21 kilograms per cubic meter, or 1.21 toe intended minus third grams per cubic centimeter. The mass is simply the gun to the times, the volume. Doing plugging that calculator, we get 2.42 grams and were asked what effect will be on our bodies? Volume and density well will obviously increase our volume and decrease air density because the density of air is much less than the average density of her body.
