Answer: The Sun and the planets formed together, 4.6 billion years ago, from a cloud of gas and dust called the solar nebula. A shock wave from a nearby supernova explosion probably initiated the collapse of the solar nebula. The Sun formed in the center, and the planets formed in a thin disk orbiting around it.
Explanation: how were the planets in the solar system formed?
Sample Response:
Producing plastics benefits the economy by employing workers and helps the economy of every state by spending billions of dollars on shipping plastic products.
Hope this helped! :3
Yes it's a test taken in high school
If the pressure, volume, and temperature are 202650 Pa, 0.004 cubic meters, and 400.15 K. Then the number of the mole is 0.24 mol.
<h3>What is thermodynamics?</h3>
It is a branch of science that deals with heat and work transfer.
We know that the Ideal gas equation is given as
PV = nRT
Where
P = Pressure (Pa)
V = Volume (in m³)
n = Number of moles (mol)
R = universal gas constant (8.314 J⋅K⁻¹⋅mol⁻¹)
T = temperature (in K)
We have
P = 2 atm = 202.65 × 10³ Pa
V = 4 liters = 0.004 m³
T = 127 °C = 400.15 K
Then we have
Then the number of the mole will be
