Much lower. Consider water's superior ability to retail heat and compare that with a metal's rapid heat gain. It takes more energy to increase the temperature of water than to heat the metal of pot (as you will no doubt know if you have burned yourself on hot metal).

How does the specific heat of water compare with that of other common substances?
Water has an abnormally high heat capacity compared to most other substances. The specific heat of water is high relative to the specific heat of other substances. Water takes a lot of energy to heat and takes a long time to lose the heat. We make use of this by using a hot water bottle to keep warm. The onshore breeze from an ocean or large lake is due to the water taking longer to lose heat than the land. The warmer body of water at the end of the day takes time to cool at night so drags air from the land; the cool body of water in the morning is responsible for air blowing onto the land in the morning. Bricks are also good heat sinks.
What are materials that conduct heat slowly called?
They are called thermal insulators or materials with high thermal resistance.
Which substance having high specific heat capacity?
A common substance with a high specific heat is water. There are a few substances that have a higher heat capacity than water, though, such as lithium and ammonia.
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.
Specific heat and latent heat of LPG?
specific heat of lpg
What are examples of heat keeping materials?
Newspaper and styrafoam.
Materials with a high specific heat can absorb heat without a large what in temperature?
change
What is heat treating used to alter?
Heat treating is generally used to alter the physical or chemical properties of materials. The most common use of heat treating is metalworking. However, it is also used to create other materials, such as glass.
Many common metals have a specific heat of what?
There is not a common specific heat among metals. The specific heat of metals ranges from .12 J / kg K for uranium to 1.83 J / kg K for Beryllium.
What term explains why some materials heat up more quickly than others?
specific heat
What materials has the highest specific heat out of silver carbon sand alcohol?
carbon
Describe specific heat capacity as varying between different materials?
Specific heat capacity is the amount of heat energy required to raise the temperature of a body per unit of mass.
How do you harness fossil fuel energy?
Most common method is convert fossil fuels to heat (rapid oxidation known as burning) that produces steam for generators or the heat generated is used directly for smelters - melt materials to produce glass, metals, and other materials.
What Rank specific heat of various materials from lowest to highest?
The specific heat of materials typically follows this general ranking from lowest to highest: metals (such as aluminum and copper), non-metallic solids (such as wood and plastic), liquids (such as water and oil), and gases (such as air and helium). However, it's important to note that specific heat values can vary depending on the specific material and its composition.
Solids that are good at moving heat from one end to the other are called?
Materials that can conduct heat are called good conductors of heat and electricity. Most of the time, these materials are metals. Nonmetals are not good conductors of heat.
Why is there a difference in time taken for different materials to cool down after being put into a beaker of hot water?
specific heat capacity is the amount of energy you have to put into a substance to raise a kg of it by 1 degree C or K. because the specific heat capacity is different for different materials, and because the flow of heat out of materials into the water is related to the temperature differencebetween the water and the objects, assuming objects placed in water have same initial temp, the objects with the higher specific heat capacities will cool less quickly.
Among common substances water has what kind of specific heat?
High (novanet)
