Physical changes can be endothermic or exothermic. An endothermic change absorbs heat from the environment while an exothermic change releases heat to the environment. Using salt to melt ice is a physical change. The diagram shows how using salt to melt ice can be used to make ice-cream. Salt is added to the ice cubes and the tin is rolled around for two minutes. This solidifies the condensed milk and sugar mixture.

Jade measured the temperature inside the tin before and after salt was added to the ice cubes. After the salt is added to the ice cubes, how does the temperature inside the tin change and is melting ice with salt is an endothermic or exothermic change?
