Question: Which of the following conversions is correct?...

Which of the following conversions is correct?

A

1 atm=1.01×104 Pa1 \mathrm {~atm} = 1.01 \times 10 ^ { 4 } \mathrm {~Pa}

B

1 mm of Hg=133 Pa\mathrm { Hg } = 133 \mathrm {~Pa}

C

D

1 torr =102 Pa= 10 ^ { 2 } \mathrm {~Pa}

Answer

1 mm of Hg=133 Pa\mathrm { Hg } = 133 \mathrm {~Pa}

Explanation

Solution

1 atm=1.01×105 Pa1 \mathrm {~atm} = 1.01 \times 10 ^ { 5 } \mathrm {~Pa}

1 mm of Hg=133 Pa\mathrm { Hg } = 133 \mathrm {~Pa}

1bar=105 Pa1 \mathrm { bar } = 10 ^ { 5 } \mathrm {~Pa}

1 torr =133 Pa= 133 \mathrm {~Pa}
