A hydrogen atom has a diameter of about 10 nm. Express this diameter in micrometers, meters, and millimeters.
MariettaO [177]

1) 1 nm = 0.001 µm; one nanometer is equal to 0.001 (10⁻³) micrometer.

d(H) = 10 nm; diameter of hydrogen atom.

d(H) = 10 nm · 0.001 µm/nm.

d(H) = 0.01 µm = 10⁻² µm.

2) 1 nm = 10⁻⁹ m ; one meter is equal to 0.0000000001 (10⁻⁹) meter.

d(H) = 10 nm.

d(H) = 10 nm · 10⁻⁹ m/nm.

d(H) = 0.00000001 m = 10⁻⁸ m.

3) 1 nm = 10⁻⁶ mm ; one nanometer is equal to 0.000001 (10⁻⁶) millimeter.

d(H) = 10 nm · 10⁻⁶ mm/nm.

d(H) = 0.00001 mm = 10⁻⁵ mm.

When the relative humidity is 90%, we say the air is: supercooled superheated saturated humid
enyata [817]

Explanation:

The amount of moisture present in air at a given temperature is known as humidity.

Whereas relative humidity is the amount of percentage of moisture it contains when compared to the maximum moisture it can contain at a given temperature.

Also % Relative humidity (RH) = \frac{P}{P_{vap}}

where,            P = the partial pressure of water vapour

              P_{vap} = the equilibrium vapor pressure at a particular temperature.

Accrding to the Clausius-Clapeyron equation, P_{vap} decreases with decrease in temperature.

Hence, it means that at super-cooled conditions the %RH would be 100%.

On the other hand, the temperature will be very high at super-heated conditions.

Hence, P_{vap} will be high hence %RH will be low.

It is also known that at saturated condition, P = P_{vap}

Therefore, %RH is 100.

Thus, we can conclude that when the relative humidity is 90%, we say the air is humid.
