TGS Calculating Latent Heat JBI

• Energy (J) = mass (kg) x Specific latent heat (J/kg)

• E = m x L

• Specific latent heat of fusion of water :334000 J/kg

• Specific latent heat of vapourisation of water: 2258000 J/kg

Calculate the quantity of heat energy required to:

Convert 2 kg of water at 100 ^oC into steam

• Energy (J) = mass (kg) x Specific latent heat (J/kg)

• E = m x L

• Specific latent heat of fusion of water :334000 J/kg

• Specific latent heat of vapourisation of water: 2258000 J/kg

Calculate the quantity of heat energy required to:

Convert 3kg of ice into water at 0 oC.

Challenge: Calculate the mass of water that can be converted into steam using 100,000J of energy
