Ling built a circuit with three light bulbs. She observed that all three light bulbs glowed. Then she removed one light bulb, and the others stopped glowing. She explained that the

other light bulbs had burned out. How could Ling test her explanation? *

(1 Point)

Replace the battery and observe whether the two lights come back on.

Take another light bulb out of the circuit and observe whether the last one comes on.

Wait another 10 min to see whether the light bulbs suddenly start glowing again.

Put the light bulb that was removed back into the circuit and observe whether the other lights come on.

Put the light bulb that was removed back into the circuit and observe whether the other lights come on.

Explanation:

If all three bulbs initially glowed and she supposes that after removing the first bulb, the others stopped glowing because they burned out, then she must replace the original bulb and see if the other two bulbs will glow.

If all three bulbs don't glow after replacing the first one, then all the bulbs may have probably burned out.

 The volume of the balloon when it is fully cooled by my refrigerator is 0.3 L

Explanation:

To calculate the final volume of the system, we use the equation given by Charles' Law. This law states that volume of the gas is directly proportional to the temperature of the gas at constant pressure.

Mathematically,

where,

are the initial volume and temperature of the gas.

are the final volume and temperature of the gas.

We are given:

Putting values in above equation, we get:

Thus the volume of the balloon when it is fully cooled by my refrigerator is 0.3 L
