Homework Answers
1.
volume = mass/density
density of ice = 917 kg/m^3
mass = 0.20 kg
Volume = (side)^3
(side)^3 = m/d
side = (0.2/917)^1/3 = 7.27*10^-5 m
side = 7.27*10^-3 cm
2.
gauge pressure = rho*g*h
rho = density of sea water = 1020 kg/m^3
Pg = 1020*9.81*10 = 100062 Pa
Pg = 1.001*10^5 Pa
2.
Pabsolute = Pgauge + Patm
Pab = 1.001*10^5 + 1.01*10^5 = 2.011*10^5 Pa
