Sure, if one object loses heat, another will gain it.
However, it might then be called heat gain.

When heat flows into a system its value is what when heat flows out of a system its value is negative?
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.
What is downward heat flow?
negative heat
Can the amount of heat needed to change temperature be negative?
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 !
Is the change in enthalpy positive or negative for an exothermic reaction?
Negative. Heat is lost.
Can q be negative when using the specific heat formula?
A negative heat capacity would mean that putting heat into something would lower its temperature, so no, it's not possible.
Is exothermic negative or positive heat?
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.
Why is the standard enthalpy change for combustion always negative?
By definition, heat given out by a reaction is always given a negative sign. Combustion gives out heat.
When flows into a system its value is positive. When heat flows out of a system its value is negative.?
heat
When flows into a system its value is positive When heat flows out of a system its value is negative?
heat
How do you know if an enthalpy is negative or positive?
The enthalpy is negative if the process emits heat. Therefore if the DeltaHrxn is negative, the reaction is exothermic.
When heat flows into a system its value is positive. When heat flows of a system its value is negative.?
when heat flows Out of a system
What reaction are characteristic of negative heat flow?
Exothermic
