How many calories are required to melt a 10 g ice cube which is at 0 c? 10, 80, 800, or 540?

Imagine that a 10 g cube at -15oC is taken from the freezer and the amount of heat required to warm the ice cube up to 0oC and melt it. So i's say 80.

Ithink the answer is b hope this

Pretty sure this would be b. the rest are trick questions. the bystanders  won't go near you if u have cpr cuffs that could hurt them. the dog will back off because the sound will scare him. and the vomits just a stupid trick. if there is that much slober and vomit on the guy hes either choking on it, or just take off his shirt.
