Ice and Snow
1 cu. ft. of ice at 320
F weighs 57.50 lbs.
1 pound of ice at 320 F
has a volume of 0.0174 cu. ft. or 30.067 cu. inches.
Relative volume of ice to water at
320 F is 1.0855, the expansion in passing into the solid state being
8.55 percent. Specific gravity of ice
=0.922, water at 620 F being 1.
At high pressures, the melting
point of ice is lower than 320 F, being at the rate of 0.0133 F for
each additional atmosphere or pressure.
Specific heat of ice is 0.504,
that of water being 1.
1 cu. ft. of fresh snow, depending on humidity of atmosphere, weighs 5 to 12 pounds.
1 cu. ft. of snow moistened and
compacted by rain weighs 15 to 50 pounds.
