Converting Pressure Units

The video tutorial explains how to convert 620 mm of mercury to atmospheres using a conversion factor. It begins by introducing the conversion factor of 1 atmosphere being equal to 760 mm of mercury. The tutorial then demonstrates the calculation process, emphasizing the importance of canceling out units to ensure accuracy. The final result of the conversion is 0.816 atmospheres.

What is the initial problem presented in the video?

• Converting atmospheres to millimeters of mercury

• Converting 620 mm of mercury to atmospheres

• Finding the volume of a gas

• Calculating the pressure in pascals

What is the conversion factor between millimeters of mercury and atmospheres?

• 1 atmosphere = 1013 mm of mercury

• 1 atmosphere = 760 mm of mercury

• 1 atmosphere = 1000 mm of mercury

• 1 atmosphere = 620 mm of mercury

Why do we place 760 mm of mercury in the denominator during the conversion?

• To convert atmospheres to pascals

• To cancel out the millimeters of mercury

• To simplify the calculation

• To increase the value of atmospheres

What is the purpose of multiplying by the conversion factor?

• To convert atmospheres to millimeters of mercury

• To cancel out the units of millimeters of mercury

• To increase the pressure value

• To find the volume of a gas

What is the final result of converting 620 mm of mercury to atmospheres?

• 0.816 atmospheres

• 1.000 atmospheres

• 0.760 atmospheres

• 1.620 atmospheres

How do you know the conversion was done correctly?

• The units of atmospheres are left

• The units of millimeters of mercury are left

• The value is greater than 1

• The value is exactly 1
