WebApr 4, 2024 · Also known as the heat of transformation, latent energy is the energy released or absorbed by a thermodynamics system or body. It occurs during a constant-temperature process and it’s usually a first-order phase transition. It is the energy that can be understood as the energy in hidden form. Weba i Define the term ‘specific latent heat of fusion ' of a substance. ii Name the liquid which has the highest specific heat capacity. iii Name two factors on which the heat absorbed or given out by a body depends.b i An equal quantity of heat is supplied to two substances A and B. Substance A shows a greater rise in temperature.
WebBecause 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 … Weblatent heat 1.

WebLatent heat is associated with changes of state, measured at a constant temperature, especially the phase changes of atmospheric water vapor, mostly vaporization, and condensation, whereas sensible heat directly affects the temperature of the atmosphere. WebNov 26, 2024 · Latent Heat of Fusion. In the case of solid to liquid phase change, the change in enthalpy required to change its state is known as the enthalpy of fusion (symbol ∆H fus; unit: J), also known as the (latent) heat of fusion. Latent heat is the amount of heat added to or removed from a substance to produce a phase change.
