When the temperature of water increases from room temperature to 90C the process of heating the water is ...

adiabatic

exothermic

isothermic

endothermic

all of the above

endothermic

Explanation:

Endothermic processes occur when a system increases in temperature which is usually caused by a heat transfer from its surroundings.

endothermic

Explanation:

Endothermic means that the substance involved in the transformation, in this case water, absorbs heat energy from its surroundings, as a consequence its temperature increases, in this case water temperature increases from room temperature to 90°C.
