Answer:
When magma cools, crystals form because the solution is super-saturated with respect to some minerals. If the magma cools quickly, the crystals do not have much time to form, so they are very small. If the magma cools slowly, then the crystals have enough time to grow and become large.
Explanation:
the pressure of a 250.0 mL volume of gas under 4.0 atm of pressure is decreased to 1.0 atm at constant tempture what is a new volume
Answer:
1000 mLExplanation:
The new volume can be found by using the formula for Boyle's law which is
[tex]P_1V_1 = P_2V_2[/tex]
Since we're finding the new volume
[tex]V_2 = \frac{P_1V_1}{P_2} \\[/tex]
We have
[tex]V_2 = \frac{250 \times 4}{1} = 1000 \\ [/tex]
We have the final answer as
1000 mLHope this helps you
A 4.00g sample of helium has a volume of 24.4L at a temperature of 25.0 C and a pressure of 1.00 atm. The volume of the helium is reduced to 10.4L, but the temperature and pressure of the gas are kept constant. What is the new quantity of the gas in moles
Answer:
0.852 mol
Explanation:
First we convert 4.00 g of helium (He) into moles, using its molar mass:
4.00 g ÷ 2 g/mol = 2 mol He
To answer this problem we can use Avogadro's law, which states that at constant pressure and temperature:
V₁n₂=V₂n₁
Where:
V₁ = 24. 4 Ln₂ = ?V₂ = 10.4 Ln₁ = 2 molWe input the data:
24.4 L * n₂ = 10.4 L * 2 molAnd solve for n₂:
n₂ = 0.852 molEurope and United States use geothermal power extensively.
True
False
Answer:
True
Explanation:
US. With an installed capacity of 3,639MW in 2018, the US is the leading producer of geothermal energy across the world, producing 16.7 billion kilowatt hours (kWh) of geothermal energy throughout the year. More recently, extensive direct heat utilization projects have been undertaken in many European countries, and electric power developed extensively in Italy and Iceland. Geothermal heat pumps became extensively used in Austria, Switzerland, Germany and Sweden (Antice, Miklos and Sanner, Burkhard, 2007).

Explanation:
it makes the most sense
Write two paragraphs about what would happen if your whole body was put in a low pressure environment ?
Answer:
Reduced air pressure also has a serious effect on the human body. Reduced air pressure means that there is less oxygen available to the body. For lungs to inflate, the air pressure in your lungs has to be less than the air outside the lungs. This is because air moves from high-pressure areas to low-pressure areas.
