what is true about the solution process involved in an instant cold pack?\nthe process is endothermic and has a negative enthalpy of solution.\nthe process is exothermic and has a negative enthalpy of solution.\nthe process is endothermic and has a positive enthalpy of solution.\nthe process is exothermic and has a positive enthalpy of solution.
Answer
Brief Explanations:
An instant cold - pack works by a process that absorbs heat from the surroundings. An endothermic process absorbs heat and has a positive enthalpy of solution (since heat is being taken in, $\Delta H_{solution}>0$). Exothermic processes release heat and have a negative enthalpy of solution.
Answer:
The process is endothermic and has a positive enthalpy of solution.
