Air has a heat capacity of 1007 J/(kg K).Water has a heat capacity of 4218 J/(kg K).There is approximately a factor of four difference.
When comparing the effective heat capacities of a column of air and a column of water, the relative masses of the columns must be considered;
A column of air extending to mean sea level (no topography) has a mass of 10^4 kg / m^2 (surface pressure divided by gravity). Thus a column of atmosphere has a heat capacity of about 10^7 J/m^2.
The same mass is found in 10 meters depth of water. Thus, a column of water has a heat capacity of 4*10^7 * (depth / 10 m) J/m^2.
Thus, when comparing the heat capacity of a water column and an air column, there is a factor of four difference for the heat capacity and a factor of water depth / 10 meters for the masses. For example, a 50 meter column of water (typical mixed layer depth) has 4*50/10 = 20 times that of air.
I would love to know some values for the land surface... that's how I ended up here.

Why is land hotter than water?
Because land needs the sun. Suppose the water was in a frying pan. And then think about land in a frying pan. Land is a solid, water is a liquid thus the molecules are moving around if they are heated. And think about a blacktop if you step barefoot on it it will hurt because the color attracts light and so does land. Water is transparent meaning the color soesnt attract the sunlight as much as land.
What are some specific heat questions that can help deepen understanding of the concept?
Some specific heat questions that can deepen understanding of the concept include: How does the specific heat of a substance affect its ability to absorb or release heat? Why do different substances have different specific heat capacities? How does the specific heat of a substance relate to its temperature change when heat is added or removed? How can the specific heat of a substance be experimentally determined? How does the specific heat of a substance impact its thermal conductivity and overall heat transfer properties?
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.
How do you use the word specific heat in a sentence?
Specific heat is the amount of heat required to raise the temperature of one gram of a substance by one degree Celsius. For example, when cooking, the specific heat of water means that it takes longer to heat up compared to oil because water has a higher specific heat.
What is the specific heat of germanium?
The specific heat of germanium is approximately 0.32 J/g°C.
Is a result of the specific heat differences between land and ocean?
Breezes are created when there are specific heat differences between land and ocean.
What accounts for the differences in the amount of temperature change between water and land?
their specific heat, the specific heat is the amount of jewls (unit of work) divided by mass (kg). land has an average specific heat of 300-800. water has a specific heat of 4180 which means it takes much more energy to heat up or cool it down
Why do land and water heat and cool at different rates?
Land and water heat and cool at different rates due to differences in their specific heat capacities. Water has a higher specific heat capacity than land, meaning it can absorb and retain more heat energy before its temperature changes. This causes water to heat up and cool down more slowly compared to land.
How does the specific heat of land affect climate?
Land with a low specific heat will heat up and cool down quickly, leading to larger temperature variations throughout the day and across seasons. In contrast, land with a high specific heat will heat up and cool down more slowly, resulting in more stable temperatures. This can influence climate patterns by affecting the distribution of heat energy in the atmosphere.
How does land and water absorb and release heat?
Land absorbs and releases heat faster than water due to its lower specific heat capacity. Specific heat is the amount of energy needed to raise the temperature of a substance by 1 degree Celsius. Water's higher specific heat allows it to absorb and release heat more slowly than land, which leads to more stable temperatures near water bodies.
Which has the highest specific heat value -land or water?
WATER
Which takes longer to heat up land or water Why?
Water takes longer to heat up than land because it has a higher specific heat capacity. This means that water can absorb more heat energy before its temperature rises significantly compared to land. Land heats up and cools down more quickly due to its lower specific heat capacity.
Does land absorbs heat faster?
Yes, land absorbs heat faster than water because it has a lower specific heat capacity. This means that land can heat up and cool down more quickly than water.
How does specific heat affect local winds?
Specific heat refers to the amount of heat energy required to raise the temperature of a substance. In the context of local winds, specific heat affects the temperature of the land and water. Land has a lower specific heat compared to water, meaning it heats up and cools down faster. This difference in specific heat causes differential heating, leading to temperature differences and the formation of local wind patterns such as sea breezes and land breezes.
What is a result of the specific heat differences between land and ocean?
Breezes are created when there are specific heat differences between land and ocean.
What cools down faster water or land?
Land tends to cool down faster than water because water has a higher specific heat capacity, meaning it can hold onto heat longer. Land loses heat more quickly because it has a lower specific heat capacity and can cool down faster at night.
How do water and land heat up and cool down differently from each other?
Water has a higher specific heat capacity than land, meaning it takes longer to heat up and cool down. Land heats up and cools down more quickly because it has a lower specific heat capacity. Additionally, water can circulate heat more effectively through currents and convection, while land transfers heat mainly through conduction.
