Air has a higher shc. More heat would be required to raise the temperature of air than water since it is a poorer conducter of heat :-) hope that helped.
------------------------------
Correction: Values for specific heat capacity Cp Air: 1.0035 J/(g*K) Water: 4.1813 J/(g*K)
Therefore water has the higher specific heat capacity. Gases usually have low heat capacities since not much more energy is required to increase the average kinetic energy of the molecules by the same amount as would be for a liquid.
What else can I help you with?
Which has the greater specific heat capacity- an object that cools quickly or an object of the same mass that cools more slowly?
The object that cools more slowly would have the greater specific heat, because the amount of heat that is needed to raise the temperature of it one degree is less than the amount of heat needed to raise the temperature of the first object one degree. i.e. the object that cools quickly does so because it doesn't need a lot of heat to increase the temperature of it by one degree and the one that cools more slowly does so because it needs more heat to increase the temperature of it by one degree.
What are the differences in heat transfer mechanisms between water and air?
The main differences in heat transfer mechanisms between water and air are their thermal conductivity and specific heat capacity. Water has a higher thermal conductivity and specific heat capacity compared to air, meaning it can absorb and transfer heat more efficiently. This is why water is often used as a coolant in systems that require high heat transfer rates, while air is commonly used for insulation or as a medium for heat exchange in HVAC systems.
Why does water heat slower then air?
Water has a higher specific heat capacity than air, which means it requires more energy to raise its temperature. Additionally, water has a higher density than air, so it takes longer for heat to transfer through water compared to air. Overall, these properties make water heat up slower than air.
What is the thermal capacity of air and how does it affect the transfer of heat in various environments?
The thermal capacity of air refers to its ability to store and release heat. Air has a low thermal capacity compared to other substances like water or metal. This means that air heats up and cools down quickly. In environments where air is the medium for heat transfer, such as in convection, the low thermal capacity of air results in faster heat transfer compared to mediums with higher thermal capacities.
What is the amount of heat in air?
The amount of heat in air is measured using the specific heat capacity of air, which is about 1 kJ/kg°C. The total heat in air can be calculated by multiplying the specific heat capacity with the mass of air and the change in temperature.
Why does water not heat up or cool as quickly as air?
Because the specific heat of water is very high. In fact, water has about 1400 times more heat carrying capacity than air.
Why does the air temperature get warmer quicker than water?
Air has a lower heat capacity and thermal conductivity compared to water, which allows it to warm up or cool down more quickly. This means that air temperature can change rapidly in response to external factors such as sunlight or wind, while water takes longer to heat up and cool down due to its higher heat capacity and thermal conductivity.
Which has the greater specific heat capacity- an object that cools quickly or an object of the same mass that cools more slowly?
The object that cools more slowly would have the greater specific heat, because the amount of heat that is needed to raise the temperature of it one degree is less than the amount of heat needed to raise the temperature of the first object one degree. i.e. the object that cools quickly does so because it doesn't need a lot of heat to increase the temperature of it by one degree and the one that cools more slowly does so because it needs more heat to increase the temperature of it by one degree.
Why is ocean temperature more constant than air temperature?
The specific heat of water is greater than the specific heat of air.

Which heats faster?
The air heats faster than the water because water has a higher heat capacity. As a result water takes four times more heat energy as compared to air.
Why does water heat slower then air?
Water has a higher specific heat capacity than air, which means it requires more energy to raise its temperature. Additionally, water has a higher density than air, so it takes longer for heat to transfer through water compared to air. Overall, these properties make water heat up slower than air.
Why does water not heat up or cool off as air?
Water has a high specific heat capacity compared to air, meaning it can absorb or release a lot of heat energy before its temperature changes significantly. This property allows water to maintain a relatively stable temperature compared to air, which has a lower specific heat capacity and can heat up or cool down more quickly.
Which ice melt faster in water or air?
Assuming that the air and water in your question have the same temperature, ice would melt faster in the water, as there is a greater degree of heat transferance in water due to its greater density.

How does humid air hold more heat compared to dry air?
Humid air holds more heat compared to dry air because water vapor in the air can absorb and retain more heat energy than dry air. This is because water molecules have a higher heat capacity than air molecules, allowing them to store more heat energy.
