HELPPP PLEASEEE How does a glass of juice become cold when you add ice to it?
aThe ice makes the glass colder so the juice becomes colder.
bThe ice cools the glass of juice because the slow moving particles in the ice cause the particles of the juice to slow down.
cIce is colder than the juice. The cold travel from cold to warm until both items are the same temperature.
dThe juice is warmer than the ice. Heat travels in one direction until both items are the same temperature.

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: 1. prepare 100 footballs. 2. measure each football's air pressure. 3. divide footballs into 10 groups. 4. place the groups in 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. what two terms best describe the variable "air pressure inside the football" in this experiment? independent, qualitative independent, quantitative dependent, qualitative dependent, quantitative
