Arrange the following units in the decreasing order of their value

A

1 cal `gt` 1 erg `gt` 1 eV `gt` 1 Joule

B

1 cal `gt` 1 Joule `gt` 1 erg `gt` 1 eV

C

1 cal `gt` 1 eV `gt` 1 erg `gt` 1 Joule

D

1 Joule `gt` 1 eV `gt` 1 erg `gt` 1 cal

Text Solution

Verified by Experts

The correct Answer is:
B
1 cal gt 1 joulegt1 erg gt 1 eV
1 eV=1.602`xx10^(-19)J`
1 erg`=10^(-7)J`
1 cal=4.184 J
