Question

Convert:

 i. 3.5 atm to mm Hg 

ii. 1520 torr to atm 

iii. 5 m³ to dm³  

iv. 580 °c to Kelvin

Answer 1

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
