Answer:
5.995 psi
Explanation:
30 psi = 2.04 atm
75 mL = 0.075 L
15 mL = 0.015 L
0.075 L/ 2.04 atm = 0.015 L/x
0.075x = 0.0306
x = 0.408
0.408 atm = 5.995 psi
First, we will convert the mass of the gallon to grams:
a gallon of water has a mass of 3.79 * 1000 = 3790 grams of water
number of moles can be calculated using the following rule:
number of moles = mass / molar mass
Therefore,
number of moles = 3790 / 18.02 = 210.32 moles
As concentrated energy is used to do WORK, it becomes spread out.
The universe is made up of constant supply of energy. Energy is use to do work; the usefulness of energy is been degraded as it is been used to carry out work. For instance, the energy in petrol is used to run motor vehicles, the process result in the conversion of the chemical energy in the petrol to heat energy. The heat energy that is produced can not be easily gathered and used again, thus, the usefulness of that heat energy has been degraded.
Answer:
Water's unique density, high specific heat, cohesion, adhesion, and solvent abilities allow it to support life.
