Use the same ionic compound from Investigation 2.A for Investigation 2.B. Read through the protocol below and determine the amounts of water you will use for each trial before starting your investigation.

Protocol Investigation 2.B – Vary the amount of water

• You will need to use the same ionic compound used in the first part of Investigation 2.
• You will need to vary the amount of water, staying within the 2-10 mL range.
• You will need to keep the amount of ionic compound constant, at 1 gram.
• You will need to record the initial temperature of each individually as well as the greatest difference in temperature from the starting temperature of the water/ionic compound mixture.
• Complete three trials.
