Dalton's Law of Partial Pressures. The total pressure of a mixture of gases is equal to the sum of the partial pressures of the component gases. PressureTotal = PressureGas 1 + PressureGas 2 + PressureGas 3 + ...

Dalton's law of partial pressures

Dalton's law of partial pressures states that the total pressure of a mixture of gases is the sum of the partial pressures of its components: P Total = P gas 1 + P gas 2 + P gas 3 .

so,

PressureTotal = PressureGas 1 + PressureGas 2 + PressureGas 3 + ... PressureGas n

An alternative of this equation can be used to determine the partial pressure of an individual gas in the mixture.

If the total pressure is known and the moles of each component gas are known, the partial pressure can be computed using the formula:

Px = PTotal ( nx / nTotal )

where:

Px = partial pressure of gas x PTotal = total pressure of all gases nx = number of moles of gas x nTotal = number of moles of all gases

Answer 2

Answer:

Liquid water has one of the highest specific heats among common substances, about 4182 J/(K kg) at 20 °C; but that of ice just below 0 °C is only 2093 J/(K kg).
