How is a light bulb related to radiation?

Chemistry
1 answer:
ElenaW [278]3 years ago
5 0

Answer:

As light is emitted from the filament, the energy in the metal is replaced as lightbulbs absorb background radiation. This prevents the filament from burning out quickly but the radiation cannot be used as power so electricity is still required for the lightbulb to work.

Need help !!!!! Stuck
Leya [2.2K]
<h2>Hello!</h2>

The answer is:

The new pressure will be equal to 6 atm.

P_{2}=6atm

<h2>Why?</h2>

Since we know that the temperature is constant, we can use the Boyle's Law to solve the problem.

The Boyle's Law establishes that when the temperature is kept constant, the pressure and the volume will be proportional.

So, we have the equation:

P_{1}V_{1}=P_{2}V_{2}

We are given,

P_{1}=2atm\\V_{1}=150mL\\V_{2}=50mL

Substituting and isolating P_{2} from the Boyle's Law, we have:

P_{1}V_{1}=P_{2}V_{2}\\\\P_{2}=\frac{P_{1}V_{1}}{V_{2}}\\\\P_{2}=\frac{2atm*150mL}{50mL}=6atm

Hence, the new pressure will be equal to 6 atm.

P_{2}=6atm

Have a nice day!
