What happens to the temperature when salt is added to water?

If we have icy water in a beaker, the temperature of the system is around 0 degrees Celsius. If we add some NaCl to this water, what happens to the temperature? Explain your answer using intermolecular forces.

My answer:

The NaCl disrupts the hydrogen bonds between water. The slightly positive hydrogen is attracted to the chlorine anions. The slightly negative oxygen is attracted to sodium cations. This will cause the ice to melt.

But the question asks what happens to the temperature. I researched that the freezing point is lowered. But I can't find anything on what happens to the temp.

Any help would be greatly appreciated.
