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 else can I help you with?
How can you found out the amount of solid dissolved in pond water?
To find the amount of solid dissolved in pond water, you can conduct a process called gravimetric analysis. This involves evaporating a known volume of pond water to dryness and then measuring the remaining solid residue. The difference in weight will give you the amount of solids dissolved in the pond water.
How many moles of NH4NO3(s) must be dissolved in water so that 73.0 kJ of heat is absorbed from the water?
To determine how many moles of NH4NO3(s) must be dissolved to absorb 73.0 kJ of heat, you need to know the heat of solution (enthalpy change) for NH4NO3. The dissolution of NH4NO3 is typically endothermic, with a heat of solution of about +25.7 kJ/mol. By dividing the total heat absorbed (73.0 kJ) by the heat of solution (25.7 kJ/mol), you find that approximately 2.85 moles of NH4NO3 must be dissolved to absorb that amount of heat.
Dose the amount of water in a jug affect its boiling point?
No but it will take longer for all the water to heat up, if it where less it would be faster for it to get to 100 degrees C.
How does the shape of the container affect the freezing rate of water?
The amount of water in a container will affect how fast it heats up. If there is a small amount of water in a container the water will biol/heat faster. However, if there is a big amount of water it will take longer for the heat to reach all parts of the water resulting in a longer time for the water to boil/heat
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.
Does the amount of water affect its temp?
No, the amount of water does not affect its temperature. The temperature of water is determined by the amount of heat energy it contains, regardless of the quantity of water present.
What does not affect the amount of heat a body can store?
The type of material does not affect the amount of heat a body can store. The factors that affect the amount of heat a body can store include its mass, specific heat capacity, and temperature difference.
Does the mass of water affect temperature rise?
Yes due to something called 'specific heat capacity', this is basically that the more water there is, the hotter it can get.
What substance does not evolve heat when dissolved in water Na2SO4 NaOH CaO NaCl?
Na2SO4 and NaCl
Does heat effect when dissolving salt?
Yes, heat can speed up the process of dissolving salt in water because it increases the kinetic energy of the salt particles, causing them to move faster and break apart more easily. However, once the salt is fully dissolved, the temperature does not affect the amount that can be dissolved in a solution.

Does the amount of water affect when the water boils?
yes. the more water the longer it would take for the heating element to heat the water. the less water, the less time it would take to heat.
Which one among the following substances evolves heat when dissolved in water?
Table salt (sodium chloride) typically releases heat when dissolved in water.
Can sodium chloride conduct in heat?
Sodium chloride (table salt) can conduct electricity in its molten state or when dissolved in water, but not in its solid form. Heat does not directly affect its ability to conduct electricity.

Does amount of water affect how fast it freezes?
Yes, the amount of water can affect how fast it freezes. A larger volume of water will take longer to freeze compared to a smaller volume because there is more heat energy that needs to be removed to lower the temperature of the water to the freezing point.
