A science teacher mixes calcium chloride and vinegar in a test tube. He passes the test tube around for his students to feel. The students notice that the test tube is hot. The science teacher asks the students to decide if the mixing of the two chemicals involved a physical or chemical change. He also asks the students to justify their answer. Which student gave the correct response?

• Student 1: The change was physical because a temperature change occurred.

• Student 2. The change was chemical because a temperature change occurred.

• Student 3: The change was physical because the two chemicals mixed.

• Student 4: The change was chemical because the two chemicals mixed.

You notice as you run up a flight of stairs to your next class that your heart is pounding and your breathing is deeper and more rapid than when you started. After a short time setting in class, your respiration rate and heart rate seem to return to normal. You know that during exercise, your heart rate, respiration, blood pressure, and ability to hold your breath (maximum breath-holding time) change. You gather the data shown in the table below. As you exercise, why does respiration rate increase?

• Your systolic blood pressure is increasing

• Your diastolic blood pressure is decreasing.

• You are sweating and need more water vapor.

• More oxygen is needed to utilize the body's stored energy.
