1. the heat of fusion for the ice-water phase transition is 335 kj/kg at 0°c and 1 bar. the density of water is 1000 kg/m3 at these conditions, and that of ice is 915 kg/m3. develop an expression for the change of the melting temperature of ice with pressure. use this to compute the freezing point of water in denver, co where the mean atmospheric pressure is 84.6 kpa

percent abundance for cu-63 can be shown as:

63 x + 65 (1-x) = 62.9296

65 - 62.9296 = 2 x

x = 1.035

thus, percent abundance for cu-63 is 1.035

percent abundance for cu-65 can be shown as:

63 x + 65 (1-x) = 64.9278

65 - 64.9278 = 2 x

x = 0.0361

thus, percent abundance for cu-63 is 0.0361

the mass spectrum of cu-63 showing the intense peak as, this isotope is found in nature more abundantly around 92.38 % in comparison to cu-65 which is found 62.58 % naturally

the objects have the same charge.

i think tornado but not 100%
