Answer:
A
Explanation:
The solubility of a substance is directly proportional to the temperature. It means that solubility will increase with the increases in temperature. At higher temperature, the kinetic energy increased that allow the solvent molecules to break the solute particles more effectively.
Substance A has a higher solubility because the weight of substance A measured at the end of the experiment is less than the weight of substance B.
Hence, the correct answer is A.
Answer:
The sun
Explanation:
The sun is the source of energy that provides the boost for electrons during photosynthesis
Answer: Friction.
Explanation: Even though the driver has taken the foot off thr gas pedal, the acceleration of the car decreases and the friction continues.
The car slows down because the opposite force of friction continues to act and the acceleration in forward direction is continuous decreasing. Hence, the car slows down.
Answer is c photosynthesis
Nuclear energy comes from splitting of Barium atom to form Krypton atom
