Question

6. Convert :
a. Exactly 1.5 atm to pascals
b. 89 kPa to newton per square metre
(Nm)
c. 101.325 kPa to bar
d. -100° C to kelvin
e. 0.124 torr to standard atmosphere​

Answer 1

Answer:

a. Exactly 1.5 atm to pascals

1 atmosphere (atm) = 101325 Pascal (Pa)

∴ 1.5 atm = 1.5 * 101325 Pa = 151987.5 Pa

b. 89 kPa to N/m²

1 Kilopascal(kPa) = 1000 Newton per square meter(N/m²)  

∴ 89 kPa = 89 * 1000 N/m² = 89000 N/m²

c. 101.325 kPa to bar

1 bar = 100 kPa so, 1 kPa = 1/100 bar = 0.01 bar

∴ 101.325 kPa = 101.325 * 0.01 = 1.01325 bar

d. - 100℃ to Kelvin

1 ℃ = 273.15 K  

∴ -100℃ = -100 + 273.15 K = 173.15 K

e. 0.124 torr to standard atmosphere

760 torr = 1 standard atmosphere (atm)

∴ 0.124 torr = 0.124 / 760 torr = 0.000163 torr
