The specific heat of water is the amount of heat needed to raise its temperature for a certain amount. One of the water's most significant properties is that it takes a lot of heat to get hot. Precisely, water has to absorb 4.184 joules of heat for the temperature of one gram of water to increase 1 degree celsius (∘C). For comparison sake, it only takes 0.385 joules of heat to raise 1 gram of copper 1∘C.
The specific heat of water is 1 calorie/gram ∘C = 4.186 joule/gram ∘C which is higher than any other common substance. As a result, water plays a very important role in temperature regulation.
FAQs
Explain the specific heat capacity of water.? ›
What is the specific heat of water? Water's specific heat capacity is 4184 joules per kilogram per kelvin. In other words, it takes 4184 joules of heat to increase a single kilogram of liquid water's temperature by 1 degree kelvin. This allows water to absorb heat slowly, and also reemit it slowly.
What is the specific heat capacity of water explained? ›The specific heat capacity of water is 4,200 Joules per kilogram per degree Celsius (J/kg°C). This means that it takes 4,200 J to raise the temperature of 1 kg of water by 1°C. Lead will warm up and cool down fastest because it doesn't take much energy to change its temperature.
What is the specific heat capacity of water answer? ›The specific heat of water is 1 calorie/gram ∘C = 4.186 joule/gram ∘C which is higher than any other common substance.
What is the specific heat of water answers? ›Short Answer
(a) The specific heat of liquid water is c w a t e r = 4.18 J g ∘ C .
The specific heat capacity of water is 4.184 J/g °C. This means that in order to increase the temperature of 1 gram of water by 1°C, we require 4.184 Joules of energy.
What is the specific heat capacity in simple terms? ›Specific Heat Capacity : Specific heat capacity represents how much heat energy is needed to raise the temperature of a substance by one degree Celsius (or one Kelvin) per unit mass.
What is the specific heat capacity of water quizlet? ›The specific heat capacity of water is 1 cal/g·°C.
Why is water's specific heat important? ›Finally, the high specific heat of water makes it resistant to temperature change, allowing life forms to maintain relatively constant internal temperatures. The high specific heat and surface tension of water contribute to its high boiling point, helping to keep it in liquid form for most biological processes.
How to solve specific heat capacity? ›Specific heat, denoted , is calculated with the following equation: C p = Q m Δ T , where is the mass of the substance, is the amount of heat energy added to the substance, and is the change in temperature of the substance.
What is the heat capacity of water at its boiling point? ›Heat capacity of H 2 O at its boiling point is
Specific heat capacity of water is 4200J/kg/°c.
What is the specific heat capacity of water list? ›
Table of specific heat capacities

Water is famous for its high heat capacity. 1 kilogram of water requires 4184 joules of heat to increase its temperature by 1 degree kelvin. Written as an equation, water's specific heat capacity is 4184 J ⋅ k g − 1 ⋅ K − 1 .
What is the specific heat capacity of water conversion? ›You can use the molar mass of the substance in question to convert from specific heat to molar heat capacity or vice versa. For example, the specific heat capacity of water is 4.184 J/(g*C). The molar heat capacity for water is 4.184 J/(g*C) * (18.02 g/mol) = 75.3 J/(mol*C).
What is the importance of high specific heat capacity of water? ›Water's high specific heat capacity results from its hydrogen bonds and helps regulate climate across the globe, as well as maintain temperature stability within the oceans. Hydrogen bonds between water molecules resist changes in kinetic energy in the molecules when heat is applied to water.
Why is specific heat capacity important? ›It helps us understand how different materials respond to heat and why some materials heat up or cool down faster than others. For instance, metals typically have low specific heat capacities, meaning they heat up and cool down quickly, which is why they're often used in cooking utensils.
How does the specific heat of water change with temperature? ›When water is heated from 0° C to 4°C its specific heat decreases , density increases hence volume decreases but after 4°C its specific heat increases , density decreases hence volume increases. 4°C is the temperature at which water occurs its maximum density.
What does it mean that water has a higher specific heat capacity than iron? ›Flexi Says: Water has a higher specific heat capacity than iron. This means water can absorb more heat energy without a significant rise in temperature.
