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.

What is the pH value of sea water?
The pH of sea water is typically around 8.1, making it slightly alkaline. However, this value can vary depending on the location and specific conditions of the water.
Specific gravity of liquid hydrocarbon is compared to what?
The specific gravity of liquid hydrocarbons is typically compared to the specific gravity of water, which has a value of 1. If the specific gravity of a liquid hydrocarbon is less than 1, it will float on water, and if it is greater than 1, it will sink in water.
Specific gravity of kerosene?
The specific gravity of kerosene typically ranges from 0.78 to 0.82, depending on the type and temperature of the kerosene. This value indicates that kerosene is less dense than water, as water has a specific gravity of 1.
The specific gravity of a product can be found on the material safety data sheet. How do you know if a product will sink in water?
If the specific gravity of a product is greater than 1, it will sink in water. Specific gravity is a ratio comparing the product's density to the density of water, so a value greater than 1 means the product is denser than water and will sink.
Write the expression for Ka for the dissociation of HBr?
Ka = [H+].[Br-] / [HBr] However the value of this expression is very high, because HBr is a STRONG acid, meaning that much more than 99.9% of the HBr molecules in water are protolized (ionized), making [H+] and [Br-] equal to the original (added) HBr amount, and the [HBr]-value nearly zero.
What is the expression and value for specific heat of water?
Specific heat of water is 1 calory per gram .
What is the expression for specific gravity when kerosene is used instead of distilled water?
Specific gravity is the ratio of density of material to the density of water, so when we use Kerosin instead of water then the value will be multiplied by the specific gravity of kerosin to get the actual specific gravity.
What is the specific heat value for water?
The specific heat value for water is 4.18 J/goC.
Which has the highest specific heat value -land or water?
WATER
When the specific gravity equal to density?
Specific gravity and density will have the same value when the two substances under investigation have identical densities. Density is an expression of the amount of mass per unit of volume that a substance exhibits. Specific gravity is a comparison of the density of a substance to the density of water.
Write a verbal phrase as an expression?
It means an expression that has a verb in it so basically almost all expressions. here's one : "Dipping your big toe in water" dipping is the verb and the whole thing is a phrase and an expression.
What is the pH value of sea water?
The pH of sea water is typically around 8.1, making it slightly alkaline. However, this value can vary depending on the location and specific conditions of the 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.
Specific gravity of liquid hydrocarbon is compared to what?
The specific gravity of liquid hydrocarbons is typically compared to the specific gravity of water, which has a value of 1. If the specific gravity of a liquid hydrocarbon is less than 1, it will float on water, and if it is greater than 1, it will sink in water.
What relationship exist between solubility and ksp value?
The solubility of a compound is related to its Ksp value through the equilibrium expression for the dissolution of the compound in water. The Ksp value represents the equilibrium constant for the dissolution reaction, and a higher Ksp value indicates a higher solubility of the compound in water. Essentially, the Ksp value quantitatively describes the extent to which the compound will dissolve in water.
Specific gravity of Polypropylene?
The specific gravity of polypropylene typically ranges from 0.89 to 0.91. This value means that polypropylene is slightly lighter than water, as the specific gravity of water is 1.
What specific gravity will not float in water?
An object with a specific gravity greater than 1 will not float in water. Since water has a specific gravity of 1, any material with a specific gravity exceeding this value will sink. For example, metals like lead and gold have specific gravities significantly higher than 1, causing them to sink when placed in water.
