Answer:

The conductor runs a circular path from the power source, through the resistor, and back to the power source. The power source moves the existing electrons in the conductor around the circuit. This is called a current. Electrons move through a wire from the negative end to the positive end.

A 12-liter tank contains helium gas pressurized to 160 \rm atm.How many 3-liter balloons could the 12-L helium tank fill? Keep i

Vikentia [17]

Answer:

636 balloons

Explanation:

If we assume that helium gas follows an ideal gas behaviour, we can use the ideal gas law to solve this problem as follows:

We consider two different states, the initial given by the conditions of the problem statement and the final, when the tank reaches atmospheric pressure and it's no longer able to fill balloons: $P_{1}=160 atm\\V_{1}=12 L\\P_{2}=1 atm\\V_{2}= ?$
To find out what would be this volume 2, we use the Boyle's Law: $P_{1}V_{1}=P_{2}V_{2}\\V_{2}=\frac{P_{1}V_{1}}{P_{2}} \\V_{2}=\frac{160 atm \times 12L}{1 atm}\\V_{2}=1920 L$
Now we find the available volume to fill the balloons by substracting both, volume 2 and volume 1: $V_{b}=V_{2}-V_{1}=1920L-12L=1908 L$
Finally, we determine the quantity of ballons by dividing that available volume between the volume of each ballon: $B=\frac{1908L}{3L} =636 balloons$
