Answer:
Turbines.
Explanation:
Hello,
In this case, we define steam as high-energy vapor water, which has the capacity to be cooled to release energy to a system. For instance, turbines, use overheated steam to produce energy, by feeding the steam to the turbine's rotor blades in order to make the rotate and generate work. As a consequence of the rotation, the steam loses energy, for which it goes out from the turbine at low both temperature a pressure, even do, in some cases it could go out liquid so a condensation may occur.

If the humidity of the room is low, the water that contacts the air directly could evaporate and takes some energy from the bulk thus decreasing its temperature steadily. This allows the water to have a lower temperature.
If the container has heat insulation, the rate of temperature drops will decrease too. Water specific heat is higher than the air, so it will need much more energy to increase water temperature.
In order to answer this question, the dimensions of the brick in centimeters need to the converted to dimensions in meters. In order to convert centimeters to meters you need to divide by 100. Doing this yields brick dimensions of 0.15 m x 0.06 m x 0.12 m. Multiplying the length, width and height together yields the volume of 0.00108 cubic meters.
Answer: the cell will absorb more water which can lead to haemolysis (rising and bursting of the cell)
Explanation:
Answer:
pH=11.
Explanation:
Hello!
In this case, since the data is not given, it is possible to use a similar problem like:
"An analytical chemist is titrating 185.0 mL of a 0.7500 M solution of ethylamine(C2HNH2) with a 0.4800 M solution of HNO3.ThepK,of ethylamine is 3.19. Calculate the pH of the base solution after the chemist has added 114.4 mL of the HNO3 solution to it"
Thus, for the reaction:
Tt is possible to compute the remaining moles of ethylamine via the following subtraction:
Thus, the concentration of ethylamine in solution is:
Now, we can also infer that some salt is formed, and has the following concentration:
Therefore, we can use the Henderson-Hasselbach equation to compute the resulting pOH first:
Finally, the pH turns out to be:
NOTE: keep in mind that if you have different values, you can just change them and follow the very same process here.
Best regards!
