It is because the density increases as you add salt and with all other substances the higher the density the lower the specific heat. For example water has a density of 1000 Kg m -3 and a specific heat of 4186 J/Kg. On the other hand copper has a density of 8960 Kg m -3 and a specific heat of 385 J/Kg.

Which have lowest specific heat capacity?
Among common substances, gases typically have the lowest specific heat capacities. For example, helium has one of the lowest specific heat capacities of all elements.
In which temperature water has maximum specific heat capacity?
Water has the highest specific heat capacity at 25 degrees Celsius. This means that it can absorb or release a significant amount of heat before its temperature changes, making it an effective heat buffer.
What is the heat capacity of 165g of liquid water?
The specific heat capacity of liquid water is 4.184 J/g°C. To find the heat capacity, you multiply the mass of the water (165g) by the specific heat capacity. So, the heat capacity of 165g of liquid water is 688.56 J/°C.
Which item the towel the sand or the water - has the highest specific-heat capacity?
Water has the highest specific heat capacity among the three items. This means it can absorb or release a lot of heat energy without undergoing a large change in temperature. Sand and towels have lower specific heat capacities compared to water.
What is the specific heat capacity of water and alcohol?
The specific heat capacity of water is approximately 4.18 J/g°C, while the specific heat capacity of alcohol (ethanol) is around 2.44 J/g°C. This means it takes 4.18 Joules of energy to raise the temperature of 1 gram of water by 1 degree Celsius, and 2.44 Joules for 1 gram of alcohol.
What is the specific heat capacity of cake?
The specific heat capacity of cake would vary depending on the ingredients used. Generally, foods with a higher water content have a specific heat capacity around 4.18 J/g°C, which is similar to the specific heat capacity of water. However, cakes can have additional ingredients like fats and sugars that can affect their specific heat capacity.
Which have lowest specific heat capacity?
Among common substances, gases typically have the lowest specific heat capacities. For example, helium has one of the lowest specific heat capacities of all elements.
What is the specific capacity of water?
At 20°C the specific heat capacity of water is 4.183 J/g °C or 4.183 J/gK.
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.
What has the largest specific heat capacity brick iron water or glass?
Water.
In which temperature water has maximum specific heat capacity?
Water has the highest specific heat capacity at 25 degrees Celsius. This means that it can absorb or release a significant amount of heat before its temperature changes, making it an effective heat buffer.
Does the mass of water affect temperature rise?
No, the mass of water does not affect the temperature rise when applying a fixed amount of heat. The temperature rise depends on the amount of heat energy transferred to the water, not the mass.
Water requires more energy than an equal mass of iron for its temperature to increase by a given amount because water has a greater?
Specific heat capacity. This means water can absorb more heat energy before its temperature increases compared to iron, which has a lower specific heat capacity.
How is specific heat of a substance different from the heat capacity?
Imagine 1 kg of water. This has a heat capacity. Now if you have 1000kg of water the heat capacity is obviously greater. The Specific Heat Capacity is a material constant. It specifies a set quantity. For water it is 4.184 kiloJoules per kilogram per Kelvin.
Why should you stir the water at the end of the experiment specific heat capacity?
Stirring the water at the end of the experiment helps ensure that the temperature throughout the water is uniform, which is important for accurate measurements of specific heat capacity. It helps to distribute the heat evenly and eliminate any temperature gradients that may affect the results.
What is the heat capacity of 165g of liquid water?
The specific heat capacity of liquid water is 4.184 J/g°C. To find the heat capacity, you multiply the mass of the water (165g) by the specific heat capacity. So, the heat capacity of 165g of liquid water is 688.56 J/°C.
is the specific heat of coconut water and water the same?
No, the specific heat of coconut water is typically lower than that of regular water. Coconut water has a specific heat capacity of around 3.91 J/g°C, while water has a specific heat capacity of around 4.18 J/g°C.
