What is the specific heat value for water?
The specific heat value for water is 4.18 J/goC.
Write the expression and value for the specific heat of water?
The expression for specific heat is Q = mc(delta T) where Q is the heat added, c is the specific heat, m is the mass, and delta T is the change in temperature in degrees C. Specific heat is the amount of heat per unit of mass needed to raise the temperature by 1 degree C. The specific heat of water is 1 cal/gram degree C = 4.186 joule/gram degree C. Water has a higher specific heat than most common substances.
Which has the highest specific heat value -land or water?
WATER
How would the measured value of specific heat be affected if some boiling water were carried over with the sample?
If boiling water were carried over with the sample, it would increase the measured value of the specific heat. The excess heat energy from the boiling water would contribute to raising the overall temperature of the sample, leading to a higher specific heat value being calculated.
Why does ice water cool faster than refrigerator water?
it doesnt, water has the same specific heat no matter what temperature it is at...about 4.18. Specific heat is a characteristic value of materials to resist changes in temperature (heat flow). Please rephrase the question if this is not the answer you are after
Is it possible for the specific heat of a substance to have a negative value?
No, it is not possible for the specific heat of a substance to have a negative value.
Most specific heat capacities are found by combining a substance with another with a known specific heat usually water. But How do chemists know the specific heat capacity of water in the first place?
The specific heat capacity of water was initially determined through experiments involving measuring the temperature change when a known amount of water absorbs a certain amount of heat. The relationship between the heat absorbed, temperature change, and mass of water was used to calculate the specific heat capacity of water. This value has been confirmed and refined over time through numerous experiments and calculations.
Does water heat up just as quickly as land heats up?
No, water heats up more slowly than land because water has a higher specific heat capacity. This means that it requires more energy to raise the temperature of water compared to land. Additionally, water can also distribute heat more evenly due to its higher heat capacity, which can affect the rate at which it heats up compared to land.
Why does specific heat has the same numerical value in metric and british systems?
Specific heat is dimensionless, and dimensionless units have the same value in any system. Specific heat is the ratio between two densities - that of the substance considered, and that of water. The ratio of two quantities of the same dimension will naturally be a dimensionless number.
What has higher specific heat water or lead?
Water has much higher specific heat than lead. All metals have fairly low specific heat values.
Water has a relatively low specific heat?
The specific heat of water is high. An example of an object with low specific heat would be a metal pan. Since specific heat is the energy needed to raise 1g of something 1 degree Celsius, water would have a high specific heat.
Why the experimental value of specific heat capacity is higher than the standars value?
Experimental errors would cause the experimental value of specific heat capacity to be higher than the standard value.
