Supersaturated solutions hold more of the solute at higher temperatures than they would at room temperature. Hence, the correct answer would be that the water would need to be heated to a higher temperature, which would give molecules and ions more kinetic energy, increasing solubility.
Generally, solubility increases with increase in temperature. At higher temperature, the kinetic energy of molecules in solution increase. Consequently, more of the molecules/ions of solutes collide more with each other and dissolve. At lower temperature, the molecules of the solutes crystalize out in solution.

Direction of motion. If the object exists in a plane with no outside forces acting upon it, or equal forces acting upon it, it will just sit there; however, an imbalance of force, such as an increase or decrease of force in an applied vector, will cause the object to change direction.
A. Chemical reaction. When the wood burns, new substances form (like ash) and they cannot be changed.
B. Exothermic. When combustion (burning) takes place it is an exothermic reaction. Energy is being released to its surroundings.

Answer:
- salt dissolved in water
- air in the lower levels of the Earth’s atmosphere
- leather made from cow hides
- metal after if has been molded
Explanation:
Matter is defined as material of substance which has mass and occupy physical space. Matter is some thing which contains atoms.So, from the given options the examples of matter are:
- Salt dissolved in water: salt is made up sodium and chloride where as water is made of hydrogen and oxygen
- air in the lower levels of the Earth’s atmosphere: air mixture of gases and gases are made atoms of different elements.
- leather made from cow hides: processed product from the animal skin which is also made of organic matter that is carbon , hydrogen , oxygen and nitrogen.
- metal after if has been molded; they too are made up of atoms.
1- global patterns of wind
2- warm air rises causing most warm air to go to the equator
