You would add water to the mixture to dissolve the salt. When the salt is dissolved, you have your sand alone.
Answer: 
Explanation:
Given
Mass of water in the sample is 
Temperature changes from 
to 
Change in temperature is 
We know, specific heat of water is 
Heat absorbed is given by
Thus, water absorbs of heat from hot plate.
You are made of mostly 6 elements: Oxygen, Carbon, Hydrogen, Nitrogen, Calcium, and Phosphorus. Some of these elements combine to form compounds in your body.

- In the reduction process of photosynthesis, electrons are transported from water to carbon dioxide.
- According to photon theory here the photons behave as light energy particle.
- By capturing sun energy (photons), chlorophyll aids in this process.An electron in the chlorophyll molecule gets excited from a lower to a higher energy state when chlorophyll receives energy from sunlight.
- Excessive sunshine is the main cause of leaves turning a darker green color. Lack of sunlight causes a plant's leaves to create more chlorophyll, which is what gives the plant its green hue.
- The color of the leaf is darker green than typical because of the increase in chlorophyll concentration per unit area.
<h3>What is photon theory?</h3>
The photon theory of light states that photons have simultaneous particle and wave behavior. pass through empty space at a constant speed, or "the speed of light". possess rest energy and zero mass.
