Air heats faster than water, because of two reasons:
1.the much lower density. 1 m3 of air weighs around 1,2 kg at 20 degree Celsius, while 1m3 of fresh water weighs around 1000 kg at 20 degree Celsius.
2. The heat capacity for water is around four times more than it is for air.

How much faster is a divers body heat lost through conduction in water than in air?
A diver's body heat is lost around 25 times faster in water compared to air due to the higher thermal conductivity of water. Water conducts heat more efficiently than air, leading to faster heat loss when submerged in water.
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.
When the body is in water how many times faster does it lose heat than when it is in still air?
The body loses heat around 25 times faster in water than in still air due to water's high thermal conductivity. This rapid heat loss can lead to hypothermia in cold water even if the air temperature is warm.
Why cold water thaw frozen foods faster than in air?
Cold water has a higher thermal conductivity than air, meaning it can transfer heat more efficiently. When submerged in cold water, the water extracts heat from the frozen food at a faster rate compared to in air, leading to quicker thawing.
Does ice melt faster in air?
Ice can melt faster in air compared to being in a sealed container, as the air can transfer heat more efficiently than the container. Factors such as temperature, humidity, and air circulation can affect the rate of ice melting in the air.
Why light travel faster in air than water?
Water is denser than air . Hence light travels faster in air than water.
Why does ice melt faster in air than in water?
the water may be a warmer temperature than the air. why does ice melt faster in water than in air
Why do you get sun burnt faster wet than you do dry?
Water conducts heat much better than air, and that is due greater density of water. Therefore, your body will receive more heat from hot water than from hot air that is in contact with your skin.
Does the ice cube melt faster on water or land?
The melting rate of an ice depends on the temperature of the surrounding. If the temperature is higher in the surrounding then the ice will melt at a faster rate and if the temperature is low then it will take more time to melt. The process of heat exchange is important whether it is air or water.
Why does air lose heat faster than water and soil?
Air loses heat faster than water and soil because it has a lower heat capacity, meaning it requires less energy to change its temperature. In contrast, water and soil have higher heat capacities, which allow them to absorb and retain heat more effectively, slowing down the rate at which they lose heat. Additionally, water and soil are denser and more compact compared to air, which also affects their ability to retain heat.
How does water differ from air in the way in which it transmits heat away from the body of an organism?
Water has a higher specific heat capacity than air, meaning it can absorb more heat energy before its temperature changes. Water also has a higher thermal conductivity compared to air, allowing it to transfer heat more efficiently. As a result, when an organism is in water, heat is conducted away from the body faster than in air.
Why the sand on the beach cools down faster than the ocean water?
Sand has a lower heat capacity and thermal conductivity compared to water, causing it to cool down faster when exposed to cooler air temperatures. Water has a higher heat capacity and retains heat longer, thus cooling down more slowly than sand.
