dog!
this is because the first energy comes from plants bc they can make their own food— therefore, energy :)
Answer:
Because the Earth's gravity acts on the atmosphere and holds it down, just as it does all other objects. The weight of the atmosphere is estimated to be about 5.75 quadrillion (5,750,000,000,000,000) tons. Air pressure is the "push" of the atmosphere on the Earth's surface.
We are going to apply the equation of state for ideal gasses: P*V = n*R*T where P is pressure, V is volum, n is mols of gas, T is temperature and R is a constant value of 0.082 (atm*l)/(mol*K)
We know the temperature is 45 ÂşC so in Kelvins will be = 45 + 273.16 = 318.16 K
Then in the equation:
V = n*R*T/P = 1.5 * 0.082 * 318.16 / 2.5 = 15.65 l
So volum of gas is: 15.65 liters

Explanation:
Among the most recent systems for the exploitation of geothermal energy, the most promising are the third generation ones, also called EGS (Enhanced Geothermal Systems). Their technology allows to dramatically improve energetic efficiency of both geothermal wells and dry rocks.

Answer:
Polarity in chemistry referred to physical properties of compounds related to solubility, melting and boiling properties.
Polarity of black pepper can be seen when black pepper is sprinkled on water. The balck pepper float on water and get displaced if touched.
It means black pepper is non-polar and have no difference in electronegativity between bonded atoms. Black pepper is so light in weight and non-polar, the surface tension of water keep it floating in the water.
