1. A sanidine crystal (KAlSi,0s) has a mass of 27.734 g, how much heat is released to the surroundings if the crystal is cooled
at constant pressure from 800 to 298 K? Hint: use the Cp equation and coefficients in the table from Holland and Powell (1998) to retrieve an equation for enthalpy changes.

Answer:
fine sand
Explanation:
- Permeability id a scientific index of the soil to have air and water pass through the soil pore and spaces. As clay soils have a fine texture, with loamy soils moderately textured and sandy soils coarsely textured thus permeability changes from slow to rapid.
- As sandy soil is highly permeable i.e 5.0 cm per hour and clay soils having the least i.e 0.05 permeability. Loamy soil is composed of sand, silt, and a smaller amount of clay.
- From an agricultural perspective, the soil permeability depends upon the percentage of the see-page and the chemical makeup of the soil. Thus crops can grow more easily this type of soil as the particle size is minute and fine.
