Latent Heat of Vaporization: An Example Lesson Summary Frequently Asked Questions What causes latent heat? Latent heat is the amount of heat absorbed or released divided by the mass of a substance that is changing phase. Latent heat is caused by overcoming the intermolecular forces that hold the...
Heat is an important component of phase changes. Latent heat is known as the heat required to convert a solid into a liquid or vapour phase. According to its phase, it has different names like the heat of condensation, theheatof vaporization, etc. Sometimes it is the amount of heat energy...
Hydrogen bonding allows animals to cool themselves using perspiration because such a large amount of heat is needed to break hydrogen bonds between water molecules. Hydrogen bonding keeps water in its liquid state over a wider temperature range than for any other comparable-sized molecule. ...
Tb is that the boiling temperature of the pure solvent [in K] M is that the molar mass of the solvent ΔHv is that the heat of vaporization per mole of the solvent. If the warmth of vaporization and therefore the vapor pressure of a liquid at a particular temperature is known then wi...
When a body’s constituent atoms and molecules vibrate, leading to an increase in the body’s internal energy (Thermal energy), a temperature gradient is established. Thus, thermal energy is often classified into various types on the basis of how this internal energy, in the form of heat, ...
Latent heat, energy absorbed or released by a substance during a change in its physical state (phase) that occurs without changing its temperature. The latent heat is normally expressed as the amount of heat (in units of joules or calories) per mole or u
