TRUE FALSE 4. There is no overall change in the amount of energy in chemical reactions.
TRUE FALSE 5. Energy is absorbed in exothermic reactions.
TRUE FALSE 6. An increase in temperature is a sign of an exothermic reaction.
TRUE FALSE 7. Products have less stored chemical energy than reactants in an endothermic reaction.
TRUE FALSE 8. Catalysts in living things are called enzymes.
TRUE FALSE 9. Endergonic reactions are reactions that release energy.
TRUE FALSE 10. Plants using sunlight to grow is an endergonic reaction.
TRUE FALSE 11. The difference between exergonic and exothermic is that endergonic is only the release of light and exothermic is only the release of heat.

Next a skier is pulled by a tow rope up a frictionless ski slope that makes an angle of 15 with the horizontal. the rope moves parallel to the slope with a constant speed of 0.69 m/s. the force of the rope does 800 3 of work on the skier as the skier moves a distance of 8.4 m up the incline. (a) if the rope moved with a constant speed of 2.2 m/s how much work would the force of the rope do on the skier as the skler moved a distance of 8.4 m up the incline? at what rate is the force of the rope doing work on the skier when the rope moves with a speed of (b) 0.69 m/s and (c) 2.2 m/s?
