| Heat is added to a sample of liquid water, starting at 80.°C, until the entire sample is a gas at 120.°C. This process, occurring at standard pressure, is represented by the balanced equation below. H2O(ℓ) + heat ==>H2O(g) 57 In the box in your answer booklet, using the key, draw a particle diagram to represent at least five molecules of the product of this physical change at 120.°C.
