Answer:
Igneous rock is the type of rock that forms as a result of cooling an crystallization
Explanation:
- Rocks are either sedimentary, igneous or metamorphic based on the chemical composition and the mode of formation.
- Igneous rocks are formed as a result of the cooling and crystallization of magma from volcanic eruptions.
- Igneous rocks are either intrusive, which form deep in the crust or extrusive which form on the surface of the earth.
- Sedimentary rocks are formed as a result of deposition, and cementation of sediments.
- Metamorphic rocks, on the other hand, are formed from the sedimentary and igneous rocks during the rock cycle.
Low electron affinity and large atomic radius
Metallic character decreases across a period (from left to right) and increases down a group.
Electron affinity increases from left to right within a period. This is caused by the decrease in atomic radius. Electron affinity decreases from top to bottom within a group. This is caused by the increase in atomic radius.
Answer:
Ideal gas law
Explanation:
The expression is the ideal gas law when properly written;
PV = nRT
where P is the pressure of the gas
V is the volume of the gas
n is the number of moles of the gas
R is the gas constant
T is the temperature
The ideal gas law is derieved from the three major gas laws;
--- Boyle's law, Charles's law and Avogadro's law
