Why does an egg sink in fresh water but float in salt water??

If an object is less dense than the water around it, it will float. Because salt water is denser than freshwater, some things float more easily in the ocean—or extremely salty bodies of the water, such as the Dead Sea. You can make your own dense water by adding salt to tap water.

The concentration of carbon monoxide (CO), a common air pollutant, is found in a room to be 5.7 x 10^-3 mg/cm^3. How many grams
damaskus [11]

The amount, in mg, of CO present in the room will be 191,520 mg.

<h3>Stoichiometric problem</h3>

The concentration of the gas in the room is 5.7 x 10^{-3} mg/cm3.

The dimension of the room is 3.5 m x 3.0 m x 3.2 m. This is equivalent to 350 cm x 300 cm x 320 cm.

We can obtain the volume of the room as:

                  350 x 300 x 320 = 33,600,000 cm3

The concentration is in mg/cm3, meaning that it is mass/volume.

Thus:

 mass = concentration x volume = 5.7 x 10^{-3} mg/cm3 x 33,600,000 cm3

                         = 191,520 mg

The mass of CO in the room is 191,520 mg

What pressure, in atmospheres, is exerted on the body of a diver if he is 38 ft below the surface of the water when atmospheric
Talja [164]

The pressure of diver = atmospheric pressure + water pressure

atmospheric pressure = 750 mmHg (as given) = 750 / 760 atm = 0.987 atm

Water pressure is

P = hρg

where

h = height of water = 38 ft

1 ft = 0.3048

38 ft = 11.58 m

ρ = density  = 1000 Kg / m³

g = gravitational constant  = 9.81 m/s2

P = 11.58 X 1000 X 9.81 = 113599.8 Kg / m s^2 Or N /m^2

1 N / m^2 = 1 pa = 9.869 X 10^-6 atm

P = 113599.8 Pa = 1.12 atm

Total pressure = 1.12 + 0.987 atm = 2.107 atm = 2.1 atm (two significant figures)
