Sure, if one object loses heat, another will gain it.
However, it might then be called heat gain.
Heat is energy and cannot be negative, If you are talking about heat flow then if you define outflow to be negative then inflow is positive.
negative heat
Mathematically, yes. Adding "negative heat" just means removing heat. Surely there's been a time in the past when you dropped a lump or two of negative heat into your drink. And sure enough ... once all that negative heat got into it, its temperature went down !
Negative. Heat is lost.
A negative heat capacity would mean that putting heat into something would lower its temperature, so no, it's not possible.
exothermic heat is negativeA different opinion:Heat itself cannot be negative. An exothermic reaction is a chemical reaction wherein a substance gives up heat. Since the substance is giving up energy in the form of heat, the enthalpy change of the substance is negative.
By definition, heat given out by a reaction is always given a negative sign. Combustion gives out heat.

The enthalpy is negative if the process emits heat. Therefore if the DeltaHrxn is negative, the reaction is exothermic.
