Specific Latent Heat Flashcards

All 4 cards in this deck

What is the equation for the thermal energy needed for a change of state, with units?

$Q = m \times L$
energy (J) = mass (kg) × specific latent heat (J/kg)

In specific latent heat, what change of state does 'fusion' refer to?

Melting — solid to liquid (or freezing, liquid to solid).

What is $Q = m \times L$ rearranged to find the specific latent heat $L$?

$L = \dfrac{Q}{m}$

In specific latent heat, what change of state does 'vaporisation' refer to?

Liquid to gas (or gas to liquid when condensing).
