- A hot water bath was made by adding about 250-mL of distilled water to a 400-mL beaker. The beaker was placed on a hot plate and heated until the water was about 70oC. 9.982 g KNO3 was added to a 25-mL graduated cylinder. About 8 mL of distilled water was added to the graduated cylinder and it was placed in the hot water bath. The mixture was stirred continuously with a temperature probe and heated until all the KNO3 dissolved. The solution was clear and colorless and the volume of this solution was 12.5 mL. (This initial solution is called Solution 1.) The graduated cylinder was removed from the hot water bath and, while continuing to stir, Solution 1 was allowed to cool. White crystals of KNO3 were first observed at 64.1oC.

He started by pushing an empty grocery cart with 0 kg of mass. As the shopping trip progressed, the cart increased in mass from 0 kg to 10 kg. Which argument below supports Raymond's claim that it was more difficult to push the 10 kg cart as opposed to the empty cart. O As the cart decreased in mass, Raymond had to use more force to push the cart. O As the cart increased in mass, Raymond had to use more force to push the cart. O As Raymond continued to push the cart during the duration of the trip, he became tired which made it more difficult to push the cart. O As Raymond continued to push the cart during the duration of the trip, friction began to build up on the wheels causing the cart to be more difficult to push.
