Latent Heat of Condensation - Concept. The heat emitted when one mole of a substance condenses is known as the latent heat of condensation. When water vapour condenses to create liquid droplets, latent heat of condensation is released.
May 22, 2019 · Latent heat is the amount of heat added to or removed from a substance to produce a change in phase. During vaporisation, this energy breaks down the intermolecular attractive forces, and also must provide the energy necessary to expand the gas (the pΔV work ). When latent heat is added or removed, no temperature change occurs.
Jul 22, 2017 · The latent heat of condensation of a substance is the heat liberated by a unit mass of the substance's vapor at its boiling point as it condenses into liquid phase. (It is essentially the "opposite" of the latent heat of vaporization ).
Nov 21, 2023 · The latent heat of condensation, which is the amount of heat released when gas particles condense to form liquid droplets at a fixed temperature. Example: water...
In meteorology, latent heat flux is the flux of energy from the Earth's surface to the atmosphere that is associated with evaporation or transpiration of water at the surface and subsequent condensation of water vapor in the troposphere. It is an important component of Earth's surface energy budget.
Because this energy enters or leaves a system during a phase change without causing a temperature change in the system, it is known as latent heat (latent means hidden). The three phases of matter that you frequently encounter are solid, liquid and gas (see Figure 11.8 ).
The molar heat of condensation \(\left( \Delta H_\text{cond} \right)\) is the heat released by one mole of a substance as it is converted from a gas to a liquid. Examples of calculations involving the molar heat of vaporization and condensation are illustrated.
Jul 11, 2021 · The heat \(Q\) required to change the phase of a sample of mass \(m\) is given by \[ Q = mL_f (melting/freezing),\] \[Q = mL_v (vaporization/condensation),\] where the latent heat of fusion, \(L_f\), and latent heat of vaporization, \(L_v\), are material constants that are determined experimentally.
The heat Q required to change the phase of a sample of mass m is given by \(\mathrm{Q=mL_f}\) (melting or freezing) and \(\mathrm{Q=mL_v}\) (evaporating or condensing), where \(\mathrm{L_f}\) and \(\mathrm{L_v}\) are the latent heat of fusion and the latent heat of vaporization, respectively.
If there is a temperature change, the transferred heat depends on the specific heat (see Table 14.1) whereas, for a phase change, the transferred heat depends on the latent heat. See Table 14.2.
