From the equation ∆p.e = (mgh) final - (mgh) initial
Answer:
photosynthesis is the process by which plant prepares food using carbondioxide and water in the presence of sunlight
<u>Answer:</u>
<em>Sand in a beach is warmer than the water of the sea.
</em>
<u>Explanation:</u>
<em>Water absorbs less heat from the sun</em> when compared with sand. Sand is darker and also is less reflective. Because of its darker nature, absorption of heat from the sun will be more. Due to its less reflective nature the sand wouldn’t be able to<em> reflect off the sunlight.
</em>
But water is highly reflective and can reflect off a <em>major portion of the sunlight falling on the sea</em>. The sea is also deep and thus the heat spreads through a large volume unlike in the <em>case of sand.</em> Water also has the nature of constant movement unlike sand which is stable.
<em>This factor also heats up sand more than water.
</em>
