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.

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 does the high specific heat of water have to do with the convection currents in the air at the seashore?
Water'specific heat capacity is 4200 J/Kg°C . This high specific heat capacity suggests that the water will travel long distances without losing heat . This makes the convection currents in the air last longer.
Difference between latent heat from sensible heat?
Two forms of heat are relevant in air conditioning:1. Sensible Heat2. Latent HeatSensible heatWhen an object is heated, its temperature rises as heat is added. The increase in heat is called sensible heat. Similarly, when heat is removed from an object and its temperature falls, the heat removed is also called sensible heat. Heat that causes a change in temperature in an object is called sensible heat.Latent heatAll pure substances in nature are able to change their state. Solids can become liquids (ice to water) and liquids can become gases (water to vapor) but changes such as these require the addition or removal of heat. The heat that causes these changes is called latent heat.Latent heat however, does not affect the temperature of a substance - for example, water remains at 100°C while boiling. The heat added to keep the water boiling is latent heat. Heat that causes a change of state with no change in temperature is called latent heat.Appreciating this difference is fundamental to understanding why refrigerant is used in cooling systems. It also explains why the terms 'total capacity' (sensible & latent heat) and 'sensible capacity' are used to define a unit's cooling capacity. During the cooling cycling, condensation forms within the unit due to the removal of latent heat from the air. Sensible capacity is the capacity required to lower the temperature and latent capacity is the capacity to remove the moisture from the air.
Is the velocity of light higher in water or in air?
It's greater in air than in water.
When saturated air is cooled what happens to its capacity to hold water vapor?
The capacity becomes smaller, and the water condenses out (the source of fog).
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 is ocean temperature more constant than air temperature?
The specific heat of water is greater than the specific heat of air.
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.
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.
What does the high specific heat of water have to do with the convection currents in the air at the seashore?
Water'specific heat capacity is 4200 J/Kg°C . This high specific heat capacity suggests that the water will travel long distances without losing heat . This makes the convection currents in the air last longer.
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.
Which have lowest specific heat capacity?
They will be the same because the molecular structure of the tea is the same as the molecular structure of water. The added tea to water does not affect the molecular structure of water.
Why does dry heat require higher temperatures for longer time periods to sterilize than does moist heat?
Water has a higher heat capacity than air. In other words, air is a very poor conductor of heat while water is a very efficient conductor of heat.
Why does it take water longer to cool down?
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?
Heat travels faster in water because the molecules are more tightly packed than the molecules in air, allowing more contact with ice and greater rate of heat transfer.
Air has more capacity to hold water at what?
Air has more capacity to hold water when the air is warmer. The colder the air is, the less water it can hold.
How much faster does cold water rob the body of heat then clod air?
Water causes a rate of heat exchange approximately 25 times greater than air at the same temperature.Source: USAF Publications.
