To calculate the depression of the melting point of ice, we can use the Clausius-Clapeyron equation:
ΔT = (ΔH / TΔV) * P
Where:
ΔT = depression of melting point (in K)
ΔH = enthalpy of fusion of ice (in cal/g)
T = melting point of ice (in K)
ΔV = change in volume from ice to water (in cm³/g)
P = change in pressure (in atm)
Given:
ΔH = 80 cal/g
T = 0°C = 273.15 K
ΔV = specific volume of ice and water at 0°C (which is approximately 1 cm³/g at atmospheric pressure)
P = 1 atm
Substituting the given values into the formula, we have:
ΔT = (80 cal/g / (273.15 K * 1 cm³/g)) * 1 atm
Converting the units to the desired form:
ΔT = (80 cal/g / (273.15 K * 1 cm³/g)) * (1 atm * 1 cal / 4.184 J)
Simplifying the equation:
ΔT = 0.920 K
Therefore, the depression of the melting point of ice produced by a 1 atm increase in pressure is approximately 0.920 K.
