Convert: i. 3.5 atm to mm Hg ii. 1520 torr to atm iii. 5 m3 to dm3

1.	Convert: i. 3.5 atm to mm Hg ii. 1520 torr to atm iii. 5 m3 to dm3 iv. 580 °c to Kelvin
Answer» I. 3.5 atm to mm Hg: 1 atm = 760 mm Hg ∴ 3.5 atm = 3.5 × 760 = 2660 mm Hg ii. 1520 torr to aim: 1 atm = 760 torr ∴ 1 torr = \(\frac{1}{760}\) atrn ∴ 1520 torr = \(\frac{1520}{760}\) = atm iii. 5 m³ to dm³ : 1 m³ = 10 dm³ ∴ 5m³ = 5 × dm³ = 5000 dm³ iv. 580 °C to Kelvin: T(K) = t °C + 273.15 ∴ T(K)= (580 °C) + 273.15 = 853.15 K

Convert: i. 3.5 atm to mm Hg ii. 1520 torr to atm iii. 5 m3 to dm3 iv. 580 °c to Kelvin

Answer»

I. 3.5 atm to mm Hg:

1 atm = 760 mm Hg

∴ 3.5 atm = 3.5 × 760

= 2660 mm Hg

ii. 1520 torr to aim:

1 atm = 760 torr

∴ 1 torr = \(\frac{1}{760}\) atrn

∴ 1520 torr = \(\frac{1520}{760}\) = atm

iii. 5 m³ to dm³ :

1 m³ = 10 dm³

∴ 5m³ = 5 × dm³ = 5000 dm³

iv. 580 °C to Kelvin:

T(K) = t °C + 273.15

∴ T(K)= (580 °C) + 273.15 = 853.15 K
