The dimensional formula of latent heat is given by, [M 0 L 2 T-2] Where, M = Mass; L = Length; T = Time; Derivation. Latent heat (L) = Heat × [Mass]-1. . . . . . (1) The dimensional formula of mass = [M 1 L 0 T 0] . . . . (2) Also, the dimensions of heat = dimensions of energy = dimensions of work. Since, work = force × displacement ...
Jul 7, 2024 · Dimensional Formula of Latent Heat. The dimensional formula for latent heat is as follows: M0L2T−2 M 0 L 2 T − 2. Where, M represents Mass. L represents Length. T represents Time.
Latent heat (also known as latent energy or heat of transformation) is energy released or absorbed, by a body or a thermodynamic system, during a constant-temperature process—usually a first-order phase transition, like melting or condensation.
5 days ago · Here, we will learn about latent heat, different types of latent heat along with the formula and dimension of latent heat. Latent Heat Equation. The latent heat formula is given by, L = \[\frac{Q}{M}\] Where, L = specific latent heat of a substance. Q = amount of heat. M = mass of the substance. Latent Heat Dimensional Formula. Latent heat ...
Jul 11, 2021 · Latent heat is measured in units of J/kg. Both \(L_f\) and \(L_v\) depend on the substance, particularly on the strength of its molecular forces as noted earlier. \(L_f\) and \(L_v\) are collectively called latent heat coefficients.
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.
The formula for latent heat is given by, L = Q / M. L = 400 / 2. L = 200 k.cal/kg. Latent heat is the energy released or absorbed, by a body or a thermodynamic system, during a constant-temperature process. Learn more about latent heat formula and related solved examples.
The specific latent heat (L) of a material… is a measure of the heat energy ( Q ) per mass ( m ) released or absorbed during a phase change. is defined through the formula Q = mL .
Solve the appropriate equation for the quantity to be determined (the unknown). 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.
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 ).
