Answer:

The new volume of the balloon is 8.8 L

Explanation:

Charles's Law consists of the relationship between the volume and the temperature of a certain amount of ideal gas, which is kept at a constant pressure. This law establishes that the volume is directly proportional to the temperature of the gas, that is to say that if the temperature increases, the volume of the gas increases and that on the contrary if the temperature of the gas decreases, the volume decreases.

In other words, Charles's law states that when the amount of gas and pressure are kept constant, the ratio between the volume and the temperature will always have the same value:

\frac{V}{T}=k

Having a certain volume of gas V1 that is at a temperature T1, by varying the volume of gas to a new value V2, then the temperature will change to T2, and it will be fulfilled:

\frac{V1}{T1}=\frac{V2}{T2}

In this case:

  • V1= 8.5 L
  • T1= 294 K
  • V2= ?
  • T2= 305 K

Replacing:

\frac{8.5 L}{294 K}=\frac{V2}{305 K}

Solving:

V2=305 K*\frac{8.5 L}{294 K}

V2=8.8 L

<u><em>The new volume of the balloon is 8.8 L</em></u>

What causes the bright lines seen in the emission spectrum?
Snezhnost [94]
Base in your questions that ask what cause the bright lines seen in the emission spectrum and i think the best answer to that is the H2 gas is used when protons was heated so the electron absorb all the photons and get exited and resulted by given of a light.

A fireman of 80 kg slides down a pole.When he reaches the bottom, 4.2 m below his starting point, his speed is 2.2 m/s . By how
levacccp [35]

Answer:

3099 J

Explanation:

The increase in thermal energy corresponds to the mechanical energy lost in the process.

The mechanical energy is given by the sum of gravitational potential energy and kinetic energy of the fireman:

E=K+U

At the top of the pole, the fireman has no kinetic energy, so all his mechanical energy is just potential energy:

E=U=mgh=(80 kg)(9.8 m/s^2)(4.2 m)=3293 J

When the fireman reaches the bottom, he has no gravitational potential energy, so his mechanical energy is just given by his kinetic energy:

E=K=\frac{1}{2}mv^2=\frac{1}{2}(80 kg)(2.2 m/s)^2=194 J

So, the loss in mechanical energy was

\Delta E=3293 J-194 J=3099 J

and this corresponds to the increase in thermal energy.

How to find the magnitude and direction of a magnetic field? What is the equation?
anzhelika [568]
The magnetic field lines around a long wire which carries an electric current form concentric circles around the wire. The direction of the magnetic field is perpendicular to the wire and is in the direction the fingers of your right hand would curl if you wrapped them around the wire with your thumb in the direction of the current.
hope it helps you
