What two terms best describe the variable "air pressure inside the football" in this experiment? 3 Air pressure is measured in pascals. For a professional American football game, the ball should be inflated to about 90,000 pascals. Scientists studied the effects of air temperature on the pressure inside American footballs by taking these steps: independent, qualitative independent, quantitative dependent, qualitative dependent, quantitative 1. Prepare 100 footballs. 2. Measure each football's air pressure. 3. Divide footballs into 10 groups. 4. Place the groups different lockers cooled to different air temperatures. 5. After 12 hours, remove the footballs from lockers. 6. Measure each football's pressure again. 7. Compare the new pressures to the starting pressures.
