Specific latent heat is the amount of energy required to change the state of 1 kilogram (kg) of a material without changing its temperature. As there are two boundaries, solid/liquid and...

2024年12月25日 · Calculate the specific latent heat of the liquid and state whether it is the latent heat of vaporisation or fusion. Step 1: Write the thermal energy required to change state equation. Step 2: Rearrange for latent heat. Step 3: Substitute in the values. m = 530 g = 530 × 10 -3 kg. Q = 0.6 MJ = 0.6 × 10 6 J.

2019年4月28日 · estimating specific heat capacity, using method of mixture. The specific heat capacity of a substance is the energy needed to increase the temperature of 1kg of the substance by 1K. Units are Jkg -1 K -1. When an object is heated, the kinetic energy of the particles increases – making the temperature rise.

Revise what latent heat is and how it relates to the changes in state, energy and mass of different materials as part of National 5 Physics.

Experiments to find SLH: S p e c i f i c l a t e n t h e a t o f f u s i o n : This experiment determines the specific latent heat of fusion for ice as it changes to water: Start by setting up the equipment, place the ice into a funnel above a beaker. Place the electric heater into the ice. Set up two of these arrangements

2024年10月21日 · The SI unit for specific latent heat is J kg -1. The specific latent heat of fusion of a substance is defined as the amount of heat required to change 1 kg of the substance from the solid to the liquid phase without a change in temperature.

2021年2月6日 · Specific heat of vaporization is the heat of vaporization to be added per unit mass of a liquid to be vaporized! Conclusion. The specific heat of vaporization q v describes the relationship between the mass to be vaporized m v and the heat of vaporization to be added for this purpose Q v: \begin{align}

Defining SLH. The energy required to change the phase per unit mass while at a constant temperature; L = E/m. E is energy transferred; m is the mass; When the substance changes from solid to liquid phase, this is the SLH of fusion; When the substance changes from liquid to gas phase, this is the SLH of vaporisation; SLH of fusion

The unit of measurement for specific latent heat is joules per kilogram (J/kg). →Why is it important to use the right unit when calculating specific latent heat? Using the correct unit is important because it ensures that the result accurately reflects the amount of heat energy required to change the state of the substance.
