2025年1月10日 · Thermodynamics Thermal Energy Transfer Specific Heat Capacity & Latent Heat. Water of mass 0.48 kg is increased in temperature by 0.7 K. The specific heat capacity of water is 4200 J kg -1 K -1. Calculate the amount of energy transferred to the water. Answer: Step 1: Write down the known quantities. Step 2: Write down the relevant equation.

2024年12月10日 · Learn about the specific latent heat equation in physics for your GCSE exam. This revision note includes definitions, graphs and calculations.

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...

Calculate the mass of water produced. 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.

Specific latent heat has different names for different changes of state. Specific latent heat of fusion – the specific latent heat for a change from a solid to a liquid. Specific latent heat of vaporisation – the specific latent heat for a change from a liquid to a vapour (gas).

Specific latent heat is the term used to describe the amount of energy required to change the state of a substance, there is no temperature change during a change of state. Which requires the most energy to change the state of a small amount of water or a large amount of water?

The specific latent heat of a substance is the energy needed per unit mass to change its phase. The specific heat capacity of a substance is defined as the energy needed to change the temperature of 1\ kg 1 kg of mass of a substance by 1\ K 1 K . It is symbolised by the letter c c and has units J\ kg^ {-1}\ K^ {-1} J kg−1 K −1.

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
