Answer:
a generator that allows them to convert kinetic energy into potential energy
Explanation:
Rescue workers can accomplish this by using a generator that allows them to convert kinetic energy into potential energy. Such as a crank generator, with these, they spin a crank with their hands and the generator takes that kinetic energy that is building up through the work that the rescuer is exerting and converts it to potential electric energy that can properly be used to provide energy to the batteries for their equipment. This is what is generally used for situations such as what rescuers go through when there is no electricity around.
Answer:
16.8 L
Explanation:
From the question given above, the following data were obtained:
Number of mole of He = 0.750 mole
Volume of He =?
Recall:
1 mole of any gas occupy 22.4 L at STP. This also implies that 1 mole of He occupies 22.4 L at STP.
Finally, we shall determine the volume occupied by 0.750 mole of He. This can be obtained as follow:
1 mole of He occupied 22.4 L at STP.
Therefore, 0.750 mole of He will occupy = 0.750 × 22.4 = 16.8 L at STP.
Thus, 0.750 mole of He is equivalent to 16.8 L
Answer:
333.33 KPa
Explanation:
P1V1=P2V2
p2=P1v1/v2
p2= (2.50 L* 100 kPa)/0.75 L
P2=333.33 kPa
Symbol: Hg
Made of hydrargyrum
Atomic number: 80
Atomic weight: 200.59
Poor conductor if heat and an ok conductor for electricity. Primarily used for many industrial applications and its salts have been employed therapeutically as purgatives, antisyphilitics, disinfectants, and astringents.
