Wat is considered a compound of hydrogen and oxygen and not a mixture because hydrogen and oxygen have gone through a chemical process to form the compound h2O. A mixture can generally be easily separated whereas a compound must undergo another chemical process to separate its elements. Therefore to separate oxygen and hydrogen from water a chemical process is necessary.
Answer:
Aquifer
Explanation:
Instead of snowcapped mountains that store water in advance of warmer temperatures, most of our drinking water comes from underground "mountains" of porous materials called aquifers which are replenished by rain. The Biscayne Aquifer is South Florida's lower east coast's primary source of fresh water.
Hi! I’m pretty sure the answer is B.
Answer:
Option (D)
Explanation:
In a nuclear power plant, the reactor core is comprised of various fuel assemblies. The nuclear fission takes place inside the core of the reactor, as a result of which the heat is produced immensely. This heat energy allows the water to boil and produces stream, which forces the blades of the turbines to rotate. This continuous rotation of the turbine blades ultimately generates electricity
It is one of the efficient methods as it is cheap, creates no pollution but it produces radioactive waste which is difficult to dispose of.
Thus, the excess heat in a nuclear power plant is used to rotate the turbines and produce electricity.
Hence, the correct answer is option (D).
Answer:
<em>There would be an increase in temperature and corresponding increase in the volume of the balloon</em>
Explanation:
Charles law is been here
Charles law states that the volume of a given mass of gas is directly proportional to the temperature in Kelvin, provided that the pressure on the gas is kept constant. Mathematically Charles law can be represented thus;
V∝ T
Where V is the volume of the gas and;
T is the temperature.
Relating Charles Law to the question
- The child moved outside from the room, constant atmospheric pressure is maintained.
- The temperature of the room is lower than the temperature outside.
From Charles law postulation, there would be an increase in volume because of the increased temperature, since our pressure is same.
