Endothermic & Exothermic Reactions Video Lessons

Concept: Endothermic Reactions

# Problem: More heat is derived from cooling one gram of steam at 100°C to water at 50°C than from cooling one gram of liquid water at 100°C to 50°C because a) the steam is hotter than the water. b) the steam occupies a greater volume than the water.  c) the density of water is greater than that of steam.  d) the heat of condensation is evolved.
