A metal is thought to be copper or gold. When 18 g of the metal absorbs 705 cal, its temperature rises by 35oC. The specific heat can be determined in cal/goC. What is the amount of cal that the metal absorbs?

Melting and boiling are endothermic processes. this means that these processes absorb energy from their surroundings in order to occur. use this information and the data you collected in the phase change gizmo to describe what happens to the temperature of water when you boil it, then explain why this result occurs.
