SCORPION-xisa [38]

Answer:

<u>A) Wood burning </u>

system : Wood.

surroundings : atmosphere

Enthalpy : Exothermic

<u>B) Water Freezing system </u>

System : Refrigerator

surroundings :  water in the refrigerator

enthalpy change : Endothermic

<u>C) Sweat evaporating </u>

System :  Human being

surroundings : Air nearby

Enthalpy change : exothermic

<u>D) Chemical Hand-warmer </u>

system : Hand warmer pack

Surroundings : human palms

Enthalpy Change : Exothermic

Explanation:

<u>A) Wood burning </u>

system : Wood

surroundings : atmosphere

Enthalpy : Exothermic

This system give away energy to its surroundings hence its enthalpy change is exothermic

<u>B) Water Freezing system </u>

System : Refrigerator

surroundings :  water in the refrigerator

enthalpy change : Endothermic

The system absorbs heat from what is put inside(surroundings ) of it hence this is na endothermic system

<u>C) Sweat evaporating </u>

System :  Human being

surroundings : Air nearby

Enthalpy change : exothermic

This is an exothermic reaction ( enthalpy change ) because the system gives out heat to the surrounding

<u>D) Chemical Hand-warmer </u>

system : Hand warmer pack

Surroundings : human palms

Enthalpy Change : Exothermic

There is movement of heat from the system to the surrounding hence it is an exothermic reaction
