Suppose you have a hand grenade. It and you are floating in deep space. The grenade explodes. For which systems is linear momentum conserved?

a.	The grenade shell
b.	The grenade’s explosive contents
c.	The grenade and all it contents

Linear momentum is always conserved. So I believe the answer is C.

I don't know what happens to the explosive contents though... they get comsumed in a exothermic reaction? But still the law of conservation of momentum should hold.
