 Emission spectrum is the spectrum of frequencies of electromagnetic radiation which are emitted due to an atom or molecule making a transition from a high energy state to a lower energy state.

So, the appearance of lines in an emission spectrum is caused by :

Light is released as an electron moves to a lower energy state.

A great white shark has resided at a depth where the pressure is 16 atm. If the initial volume of its swim bladder is 4 L, what
padilas [110]

Answer:

The new volume of the gas is 32L

Explanation:

P1 = 16atm

V1 = 4L

P2 = atm

V2 = ?

According to Boyle's law, the volume of a given mass of gas is inversely proportional to its volume provided the temperature remains constant.

P1 * V1 = P2 * V2

V2 = (P1 * V1) / P2

V2 = (16 * 4) / 2

V2 = 64 / 2

V2 = 32L

The new volume of the gas is 32L
