the diagram shows the heating curve of paraffin wax, which is a solid at room temperature. the solid paraffin was pack of mass 1.5kg is first heated up until it partially melts. it is then inserted at the bottom of the sleeping bag with the baby lying on top of it and wrapped around by the sleeping bag. the pack is able to keep the baby warm at about the body temperature of 37°C for a few hours. The specific heat capacity of paraffin wax is 2500J/(kgK) while the specific latent heat of fusion of paraffin wax is 2.2x 10^5 J/kg. explain why it is dangerous to use the paraffin wax pack if it has fully melted

Which phenomenon occurs during the following changes?a). Wax melts in the sun. b). Formation of clouds

explain how the partially melted paraffin wax is able to keep the temperature around 37°C when it is placed under the baby
