Explanation:</h3>
- Based on Boyle's law when temperature is held constant then the volume of a fixed mass of a gas, V is inversely proportional to Pressure, P.
- That is; Pα 1/V
- Mathematically, P= k/V where k is a constant
- Therefore, when the volume of a gas and the pressure are altered,
- P1V1=P2V2 = k, where P1 and P2 are the initial and final pressure respectively while V1 and V2 are the initial and final pressure respectively.
In this case;
Initial Pressure, P1 = 150 atm
Initial volume, V1 = 60.0 L
Final pressure, P2 = 0.925 atm
we are required to calculate the final volume
But, P1V1 =P2V2
Rearranging the formula, V2 = P1V1 ÷ P2
Thus;
V2 =(150 atm × 60.0 L) ÷ 0.925 atm
= 9,729.73 L
The new volume will be 9,729.73 L
Cathode-ray tubes are often found in oscilloscopes and computer monitors. In the figure below an electron with an initial speed of 5.70 106 m/s is projected along the axis midway between the deflection plates of a cathode-ray tube.
