Let's assume a couple things: the ice is colder than 32°F (an acceptable premise) and that adding salt to water lowers its freezing point (a widely-known phenomenon).
A property of melting/freezing, as well as of boiling/condensing, is that no further temperature change can occur until all of the substance has changed phase.* If you assume that the water in the cup is uniformly at 32°F when we begin, it will be 32°F until all the ice is gone, then begin warming to room temperature.
If you add salt to water while the ice is still melting, you lower the freezing point of the water. This is known as fusion curve depression. The ice begins to melt faster because the liquid is no longer at the freezing point. Since our premise says the ice is colder than freezing, the overall temperature of the water will be less than 32°F as soon as salt is added.
* Exceptions - superheated and supercooled substances, which are only possible in strictly controlled conditions
What else can I help you with?
Why does the temperature of tea decreases on adding sugar?
Adding sugar to tea causes the temperature to decrease because energy is required to break down the sugar crystals into individual molecules. This energy is taken from the surrounding tea, resulting in a decrease in temperature.
Is it okay if you boil water before putting it in your betta's bowl?
Its ok as long as you let the water cool to room temperature before adding the water back to the bowl, or adding the betta to the water. Also, it is completely unnesseary to boil before putting in your betta's bowl.
Does salt make water cool down faster?
No, adding salt to water does not make it cool down faster. In fact, adding salt to water lowers its freezing point, which means it will take longer to freeze but will not cool down faster.
Does seltzer in water make the temperature rise?
No, adding seltzer to water does not raise the temperature. Seltzer is simply carbonated water, which means it contains carbon dioxide gas dissolved under pressure. When the pressure is released, the gas comes out of solution as tiny bubbles, but this does not result in a temperature increase.
Why does water emit heat?
Water emits heat when it undergoes a process such as boiling or cooling down due to a transfer of energy. This energy causes the water molecules to move faster or slower, leading to a change in temperature and the release of heat.

What happens when you freeze boiling water?
When you freeze boiling water, it rapidly cools down and turns into ice. The extreme temperature change causes the water molecules to slow down and solidify, forming ice crystals.
What are you removing when you lower the temperature of water?
When you lower the temperature of water, you are removing thermal energy from the water. This causes the water molecules to slow down and come closer together, eventually leading to a phase change from liquid to solid if the temperature is lowered below the freezing point.
What happens if you add or remove energy to a glass of water?
Adding energy to a glass of water typically increases the temperature, causing the water molecules to move faster. Removing energy from the water would cause it to cool down, slowing down the movement of water molecules.
What different temperature water affects how fast the bag inflates?
The higher the temperature of the water, the faster the bag will inflate. This is because the reaction between the baking soda and vinegar that causes the bag to inflate is faster at higher temperatures. Conversely, lower temperature water will slow down the reaction and the inflation process.
Why does adding salt to water lower the temperature?
When the salt dissolves, energy is required to break the bonds between the ions in it. Since there is nowhere else to get the energy from, the water loses some of its heat to do this, and the solution then cools down.
What causes hot water tank to tick?
A hot water tank will tick when the temperature of the water is reached and it is starting to cool down. The ticking is because the metal of the tank is warm on the inside and a little cooler on the outside.
Does seltzer in water make the temperature rise?
No, adding seltzer to water does not raise the temperature. Seltzer is simply carbonated water, which means it contains carbon dioxide gas dissolved under pressure. When the pressure is released, the gas comes out of solution as tiny bubbles, but this does not result in a temperature increase.
Is there a change in temperature when ammonium chloride is added to water and being stirred?
Yes, there is a change in temperature when ammonium chloride is added to water and stirred. Ammonium chloride dissolves in water endothermically, meaning it absorbs heat from its surroundings to break down into its ionic components. This absorption of heat causes a decrease in temperature of the solution.
Why does water emit heat?
Water emits heat when it undergoes a process such as boiling or cooling down due to a transfer of energy. This energy causes the water molecules to move faster or slower, leading to a change in temperature and the release of heat.
