A balloon has a volume of 2.29 liters at a pressure of 100.0 kPa. If the pressure of the balloon is decreased to 83.5 kPa, what
Tanzania [10]

Answer: 2.74 litres

Explanation:

Given that,

Original pressure of balloon (P1) = 100.0 kPa

Original volume of balloon (V1) = 2.29 litres

New pressure of balloon (P2) = 83.5 kPa

New volume of balloon (V2) = ?

Since pressure and volume are given while temperature is held constant, apply the formula for Boyle's law

P1V1 = P2V2

100 kPa x 2.29 L = 83.5 kPa x V2

229 kPa•L = 83.5 kPa•V2

Divide both sides by 83.5 kPa

229 kPa•L/83.5 kPa = 83.5 kPa•V2/ 83.5 kPa

2.74 L = V2

Thus, the new volume of the balloon is 2.74 litres

When a sample of atoms is heated and releases light of certain wavelengths, it is called what?
rjkz [21]

The answer is emission spectrum. It is the range of frequencies of electromagnetic radiation produced because of an atom or molecule generating a transition from a high energy state to a lower energy state. The photon energy of the produced photon is equivalent to the energy change between the two states. There are many conceivable electron changes for each atom, and each change has a precise energy difference.
