How does the amount of dissolved salt in water affect how much heat it ca hold?
The amount of dissolved salt in water affects its heat capacity - the ability to hold heat. Generally, higher salt content in water lowers its specific heat capacity, meaning it can hold less heat compared to pure water. This is due to the presence of salt ions interfering with the water molecules' ability to store heat energy.
What happens if you heat up as dissolved gas?
Heating up a dissolved gas increases its kinetic energy, causing it to escape from the liquid solution as bubbles. This process is known as outgassing and is commonly seen when boiling water, where dissolved gases like oxygen and nitrogen are released into the air.
When a substance is dissolved in water the temperature of the water increases this process is known as?
This process is known as an exothermic reaction. When a substance dissolves in water, energy is released in the form of heat, causing the temperature of the water to increase.
How much heat in kj is released when 1.65 mol NaOHs is dissolved in water the molar heat of solution of NaOH is -445.1kj?
To calculate the heat released when dissolving 1.65 mol of NaOH, multiply the number of moles by the molar heat of solution. The calculation is: (1.65 , \text{mol} \times (-445.1 , \text{kJ/mol}) = -734.415 , \text{kJ}). Therefore, approximately 734.42 kJ of heat is released.
How do you remove dissolved solids from water?
You can remove dissolved solids from water using methods such as reverse osmosis, distillation, or ion exchange. These processes help separate the dissolved solids from the water, leaving you with purer, cleaner water.
What substance does not evolve heat when dissolved in water Na2SO4 NaOH CaO NaCl?
Na2SO4 and NaCl
Which one among the following substances evolves heat when dissolved in water?
Table salt (sodium chloride) typically releases heat when dissolved in water.
What is the best way to get a solid back oncr its dissolved in water?
Heat it.

How do you find out if there are any dissolved materials in water?
Generally, you heat up the water until all of the water has evaporated (changed into gas). When this happens, it leaves behind any dissolved substance.
What is an instrument used to dissolve heat?
Heat is not a physical substance which can be dissolved.
When 1.0 mol (58.44 g) of sodium chloride is dissolved in 100.0 g of water in a coffee-cup calorimeter, the temperature of the water drops from 20.0°C to 14.1°C What is the heat of solution for sodi?
The heat of solution for sodium chloride can be calculated using the formula q = mcΔT, where q is the heat absorbed or released, m is the mass of the solution, c is the specific heat capacity of water, and ΔT is the temperature change. First, calculate the heat absorbed by the water. Then subtract the heat absorbed by the water from the heat released by the dissolution of NaCl to find the heat of solution for sodium chloride.

How can sugar be dissolved in water quicker?
you can heat it up, the water, or grind the sugar into smaller particles! try both! =)
