How much ammonia (NH3) could be melted by the addition of 1 kJ of heat, if the temperature of the liquid is at the melting point? (^ H fus= 5.66 kJ/mol)

it should be all of them because it asks if you included all of those in your answer

explanation:

if the temperature drops and becomes cool

then the atmosphere can be freezing as the water vapor in the air is at maximum (100%) and can be severely cold

also can be snowing lightly as the moisture in the air will start to solidify

and btw this is not chemistry but
