Explanation:

1)

a) Wavelength of red light = 700 nm

1 nanometer = 10^{-9} meter

Wavelength of red light in meter will be:

=700 nm=700\times 10^{-9} m=7.00\times 10^{-7} m

b) Wavelength of red light = 7.00\times 10^{-7} m

1 meter  = 39.3701 inches

Wavelength of red light in inches will be:

7.00\times 10^{-7} m=7.00\times 10^{-7}\times 39.3701 inches

=2.7559\times 10^{-5} inches

2)

Value of distance given = 90.123 km

1 km = 3280.84 feet

90.123 km=90.123 \times 3280.84 feet=295,679.1433 feet

1 foot = 0.1515152 chain

295,679.1433 feet=295,679.1433\times 0.1515152 chain

=44,799.88453 feet\approx 4.48\times 10^4 chains

Value of distance in chains:

90.123 km=4.48\times 10^4 chains

What gas law applies to aerosol cans being stored in a cool place?
svetlana [45]
Don't really know if this is what your asking but P1/T1= P2/T2 should show how the pressure varies with temperature (V is left out because it's constant since the gas is trapped in an aerosol can). As the temperature rises the pressure rises and if it gets too high then the can explodes, which is why it should be stored in a cool place. There's also PV=nRT might be kind of hard to find moles (n) though.
