Interpretation: From the given figure, what happens to the energy of Ball A should be determined.
Concept Introduction: Energy is the ability to do work or produce heat. The law of conservation of energy says that the energy cannot be created or destroyed, but it can be converted from one type to another. It is also called the first law of

Answer to Problem 1ALQ
The energy of the ball A in its original position is distributed to ball B as a result of work and to the surface of the hill through heat.
Explanation of Solution
It is given that on reaching the ground, the ball A stopped moving. Considering the law of conservation of energy, the energy must be conserved. The final position gets raised due to transfer of part of energy from ball A to ball B.
The remaining energy of the ball A gets distributed to the surface of the hill in the form of heat as when it moves down the hill, some amount of the kinetic energy gets transferred to the surface of the hill. Thus, the initial energy of ball A gets transferred to the ball B in the form of work and to the hill’s surface in the form of heat.
Therefore, the energy of the ball A in its original position is distributed to ball B as a result of work and to the surface of the hill through heat.

An unknown sample of Cu2+ gave an absorbance of 0.262 in an atomic absorption analysis. Then 1.00 mL of solution containing 100.0 ppm (= µg/mL) Cu2+ was mixed with 95.0 mL of unknown, and the mixture was diluted to 100.0 mL in a volumetric flask. The absorbance of the new solution was 0.500. Calculate the concentration of copper ion in the sample.arrow_forward

The sample weighs 2.50 g initially and is heated in a controlled atmosphere. As the temperature increases, the water of hydration is released in two stages: (a) The first mass loss of 0.72 g occurs at 150°C, corresponding to the loss of a certain number of water molecules. (b) The second mass loss of 0.90 g occurs at 250°C, corresponding to the loss of the remaining water molecules.
