Answer:
Vegetation plays an important role in the water cycle by preventing soil erosion and increasing groundwater levels. Green plants also release water vapor in the air as a by-product of photosynthesis, thus involving groundwater in the water cycle.
Explanation:
The density of magnesium will be 1.74 g/cm³ if 23.5 g of magnesium occupies 13.5 cm³
<h3>What is Density ?</h3>
Density is the measurement of how tightly a material is packed together.
It is defined as the mass per unit volume.
Given ;
- Mass = 23.5 g
- Volume = 13.5 cm³
Formula to calculate density ;
Density = mass / volume
=23.5 / 13.5 = 1.74 g/cm³
Hence, the density of magnesium will be 1.74 g/cm³ if 23.5 g of magnesium occupies 13.5 cm³.

Answer:
The molar specific heat capacity of a gas at constant volume Cv is the amount of heat required to raise the temperature of 1 mol of the gas by 1◦C at the constant volume. Its value for monatomic ideal gas is 3R/2 and the value for diatomic ideal gas is 5R/2.
