If something is dissolved in water and the the water’s temperature decreases is it an endothermic reaction or exothermic? thanks!
Chemistry midterm? Heh…I could refer you to some people. 😛
Haven’t taken chemistry for a LOOOOONG time, but if I remember correctly, endothermic reactions absorb heat, and exothermic release. So I think endothermic.
endothermic. the water cooled because the heat was transferred to the solvent. (assuming the water is not a reactant.)
endothermic reaction
endo
Dare I say anything but endothermic at this point?
when the two were formed into a mixture heat was let off therefore exothermic.
in order to separate the two you need to add heats to break the bonds hence endothermic
I think (not sure, breaking my own rule here)
that the terms exothermic and endothermic reactions refer only to chemical changes, not to physical changes such as disolving in water.
but since the system has lost heat, which must have been converted to some sort of potential, this is an endothermic change, if this is an appropriate term.
