Question

1. Convert 450J into Btu, eV, erg, cal and ft-lbs.4507Tin ochI need help

Answer 1

ANSWER:

0.427 BTU

2.8*10^21 eV

4.5*10^10 erg

107.55 cal

331.9 ft-lbs

STEP-BY-STEP EXPLANATION:

We have 450 J, to convert it to other units you must know the conversion factor in each case, like this:

J into BTU

$450J\cdot\frac{1\text{ BTU}}{1055.6J}=0.427\text{ BTU}$

J into eV

$450J\cdot\frac{1\text{ eV}}{1.6022\cdot10^{-19}J}=2.8\cdot10^{21\text{ }}eV$

J into erg

$450J\cdot\frac{1\text{ erg}}{1\cdot10^{-7}J}=4.5\cdot10^{10}\text{erg}$

J into cal

$450J\cdot\frac{1\text{ cal}}{4.184J}=107.55\text{ cal}$

J into ft-lbs

$450J\cdot\frac{1\text{ ft-lbs}}{1.356J}=331.9\text{ ft-lbs}$
