A volcano is created when hot molten rock, ash and gases escape from an opening in the Earth's surface. The molten rock and ash solidify as they cool, forming the distinctive volcano shape shown here. As a volcano erupts, it spills lava that flows downslope. Hot ash and gases are thrown into the air.
If a solution is saturated, that means it already posses the maximum number of solutes thus have been dissolved in it, and thus the concentration cannot be increased.
True! The answer is true because I did this today and got that answer and it was right!
Answer: The correct answer is option B.
Explanation:
Average kinetic energy of the gas molecule is given by relation:
= Avogadro Number
T = Temperature of the gas in Kelvins.
R = Universal gas constant
With increase in temperature the kinetic energy of the gas molecule increases and vice-versa.
So, according to the question the explanation for a drop in temperature of the gas is decrease in average kinetic energy of the gas molecules.
Hence, the correct answer is option B.
To round 409,614 to the nearest thousand you have to eliminate the units, the tens and the hundreds, and then round the number in the place of the thousands according to the number eliminated from the place of the hundreds: if the eliminated number is smaller than 5, the number in the thousands is increased in one unit; if the eliminated number is 5 or greater, then the number of the thousands must be increased in one unit. Given that the number in the hundreds is 6, you have to increase 409 to 410 ant the resultant number is 410,000. <span>Answer: 410,000.</span>
