Recrystallization is when new mineral grains form as a result of metarmorphic heat that are larger than the original mineral grains.
Recrystallization is a metamorphic process that occurs under situations of intense temperature and pressure where grains, atoms or molecules of a rock or mineral are packed closer together, creating a new crystal structure.
Explanation:
Lime is an oxide of calcium(CaO). As a metallic oxide, it produces a basic solution when it reacts with water.
- The main reason why lime is added to lakes is to reduce acidity in the lake water.
Bottom muds in lakes are usually acidic and makes the water hypertonic. When lime is added, it reduces the pH of the water and causes acidity to reduce.
- Lime also helps to reduce the hardness of lake water to a good level.
- Lime also helps to release nutrients useful for photosynthesis of plants in the lake.

GravitationL force is equal to the mass of the object multiplied by the acceleration due to gravity. Assuming that this object is on earth, the acceleration due to gravity is 9.8 m/s^2. Therefore, 10 kg multiplied by 9.8 m/s^2 is equal to 98 N for the gravitational force.
Therefore, the gravitational force acting on an object that has a mass of 10.0 kg (assuming this object is on earth) is 98 N.
