AHMAD, ASHNA 5 of 35 1 4. 6. 7 A student has two rubber balls of different masses to perform an experiment. Which experiment can the student do to objects? O Roll the rubber balls on thick carpet, and observe if either ball produces a spark. O Move a magnet near each rubber ball, and observe if either ball is attracted to the magnet. O Place the rubber balls ona rough surface, apply a small push, and record the time for each ball to move 30 cm. O Drop the rubber balls at the same time from 5 m, and record the time for each ball to hit the ground. P Type here to search 5.

MODIFIED TRUE OR FALSE.: A if both statements are true B if the 1 statement is false and the 2nd statement is true C if the 1st statement is true and the 2d statement is false D if both statements are false 1. Thermodynamics is a branch of physical chemistry that deals with thermal changes. Thermochemistry determines the quantities of energy emitted or absorbed. 2. Changes that seem to happen by themselves in one direction are spontaneous reactions. The meiting of ice is an exothermic reaction. 3. A portion that is singled out in a study where energy can be transferred back and forth is called the surroundings. A thermochemical system where neither energy can be exchanged with its surroundings is called a closed system. 4. Compounds formed from their elements in exothermic reaction have negative AH, lonic compounds…
