Includes a table of latent heat values for water, oxygen, and silver, plus two worked examples to practise substituting values into Q = m × L and rearranging to find unknown quantities. Learning outcomes cover choosing the correct latent heat type, converting units to standard form, and solving algebraic equations. Followed by practice questions and an answers section.","P6.5  \nStudent calculation sheet  \nName   Class   Date    \n Latent heat  \nSpecification references:  \n􀁸 P3 .2.3 Changes of heat and specific latent heat  \n􀁸 M1a, M3b, M3c, M3d, M4a  \nAims  \nIn this worksheet, you will work through two worked examples designed to allow you to improve your maths skills.
