write your answer clearly
Light of certain energy shines on a metal and causes
electrons to be emitted. Based on the
research of Albert Einstein, the change that would most likely result in
stopping the emission of electrons from this metal is to coat the metal.
<u>Answer:</u>
The correct answer option is 1.6 atm.
<u>Explanation:</u>
We know that there is a sample gas which has a volume of 2.4 L with a pressure 1.2 atm and we are to find the pressure of the same gas sample if its volume is reduced to 1.8 L at a constant temperature.
We will apply the Boyle's law here which states that the "pressure of a given mass of an ideal gas is inversely proportional to its volume at a constant temperature".
<em>
</em>
Substituting the values in the formula to get:

Therefore, the pressure of the same gas sample will be 1.6 atm if the volume is reduced to 1.8 L at a constant temperature.
