Why does the temperature stay the same when two states of matter are present?

• Because the energy is used to speed up the particles

• Because the energy is used to change the particle's attraction

• Because the energy is used to multiply the particles

During a lab investigation, students followed this procedure: 1. Measure the mass and length of a piece of chalk. 2. Place the piece of chalk in a small beaker. 3. Cover the chalk with vinegar. 4. Record observations. Students observed bubbles immediately forming around the chalk. After the bubbles stopped forming, the students noticed that the chalk was smaller. Some students tried to recover the missing chalk from the vinegar, but no chalk particles were visible. What kind of change did the chalk undergo AND what evidence could be used to support the answer? Think about the question carefully. Then record your answer and evidence in the box provided.

• Unknown Substance 1

• Unknown Substance 2

• Unknown Substance 3

• None of them
