AQA Physics P6.5 GCSE Student practical Class . ..."; Date ........."; The specific latent heat of vaporisation of water is higher than the specific latent heat of vaporisation of ethanol. What does that suggest about the strength of the intermolecular forces in liquid water compared with liquid ethanol? (1 mark) A 5 g ice cube at 0 .C is placed into 20 g of water at 30 .C and left until it has all melted. a Show that the new temperature of the water is approximately 10 .C, using: latent heat of fusion of ice cube = heat energy lost by water. (8 marks) b The calculation in a does not take into account the energy used to warm up the water from the melted ice cube to the final temperature of the water. Suggest why this does not significantly affect the answer.
