What else can I help you with?
Will a temperature of a beaker of water increase or decrease when its mixed with salt?
This is the typr of experiment that is performed with a 'Slurry' of ice and water in the beaker, and not just room temperature water. Adding salt to a slurry will cause some of the ice to melt. When ice melts, the temperature of the solution will drop, and potentially below the freezing point of pure water.If the water and salt are at room temperature, the mixing will yield no significant changes in temperature.
What happens to thermal energy in a beaker when it is cooled down?
When a beaker is cooled down, thermal energy is transferred from the beaker to the surroundings. The molecules in the beaker lose kinetic energy, which causes the temperature of the beaker to decrease. This transfer of thermal energy continues until the beaker reaches thermal equilibrium with its surroundings.
What happens to the pH in the beaker as the acid is added?
The pH drops. The stronger the acid the lower the pH.
What happens to mercury in a beaker heats up?
As mercury heats up in a beaker, it will expand due to the increase in temperature. This expansion can cause the level of the mercury in the beaker to rise, potentially overflowing if the volume increases significantly. Additionally, as the temperature continues to rise, the mercury may vaporize and release potentially harmful fumes into the air.
What happens when sodium chloride was added as a solute in the left beaker?
When sodium chloride is added to water, it will dissociate into sodium ions and chloride ions. These ions will increase the concentration of solute particles in the solution, lowering the freezing point and increasing the boiling point of the solvent. This property is known as colligative properties.
When ammonium chloride dissolves in a beaker of water the beaker becomes cold to the touch explain this phenomenon?
When the ammonium chloride dissolves in the water, it is an endothermic reaction. The energy for the reaction comes from the water. Since the water is losing energy, the temperature of the solution decreases, which in turn decreases the temperature of the beaker because of heat transfer.

What is the temperature of the beaker holding the reacting substance decrease is it endothermic or exothermic?
The way I remember it: endo (think in). Heat is flowing in to the reaction from the surroundings. Heat flows from hot to cold, so the measured temperature decreases. The actual beaker will decrease temperature as well, since it is next to something that has decreased in temperature.

The molecules in the beaker lose kinetic energy, which causes the temperature of the beaker to decrease.

A sample of ammonium nitrate is placed in a beaker of water and immediately begins to dissolve What exactly occurs during this process?
The temperature will decrease
Is calcium chloride and potassium chloride crystals in a beaker a pure substance?
Calcium chloride and potassium chloride are pure substances.
How does is the temperature of beaker measure in water?
The temperature of a beaker is typically measured using a thermometer that is placed in the water inside the beaker. The thermometer will provide a reading of the water temperature, which indirectly reflects the temperature of the beaker as well.
What happens to the pH in the beaker as the acid is added?
The pH drops. The stronger the acid the lower the pH.

The temperature of true water is in a beaker is 25 c after adding a piece of magnesium to the water the temperature increase is this an exothermic or an endo thermetic?
exothermic ? because energy released
A reaction is taking place in a beaker and the outside of the beaker goes very cold What kind of reaction is taking place?
The reaction is likely an endothermic reaction. In an endothermic reaction, heat is absorbed from the surroundings, causing a decrease in temperature.
What happens when sodium chloride was added as a solute in the left beaker?
When sodium chloride is added to water, it will dissociate into sodium ions and chloride ions. These ions will increase the concentration of solute particles in the solution, lowering the freezing point and increasing the boiling point of the solvent.
