<span>During freezing heat will be released. Normally we wont think like that ,but the reality is during freezing the heat get released. the liquid water will have more energy than the frozen water .so during this transition the energy of the water get released as the latent heat. Basically when we need to reduce the temperature ie. freezing a substance, the heat already absorbed in the substance should be released out of the substance.</span>
Answer:
ΔT = 0.61°C
Explanation:
That's the formula for the colligative property of freezing point depression:
ΔT = m . Kf . i
AlCl₃ is a ionic salt that be dissociated:
AlCl₃ → Al³⁺ + 3Cl⁻ i = 4
In solution, we can have 4 moles of ions, 1 mol of Al³⁺ plus 3 moles of chloride. (We assume 100 %ionization)
Let's replace data: ΔT = 0.082 m . 1.86 °C/m . 4
ΔT = 0.61°C
The reason wet clothes spread out dry faster than when left in a pile is because there is more surface area therefore the rate of evaporation increases and this decreases the time it takes for the water molecules to diffuse into the air.
