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.
How many square feet will a 28000 btu gas fireplace heat?
look in a chemistry textbook and find the specific heat capacity of air. that is how much energy (in BTUs) it takes to raise the temperature of 1 litre of air by 1 degree. multiply that number by the volume of your room (in liters) then divide 27000 by that number. in maths you want 27000/(volume of room*specific heat capacity of air)
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.
Air has a lower specific heat then water. once the the sun goesdown will air or the water cool off faster why?
Air will cool off faster than water once the sun goes down because it has a lower specific heat capacity. This means that air requires less energy to change its temperature compared to water. Consequently, when heat is lost, the temperature of the air decreases more rapidly than that of the surrounding water, which retains heat longer due to its higher specific 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.
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.
What is the specific heat capacity of air in kilojoules per kilogram degree Celsius?
The specific heat capacity of air is approximately 1.005 kilojoules per kilogram degree Celsius.
What is the specific heat capacity of air in kilojoules per kilogram per kelvin?
The specific heat capacity of air is approximately 1.005 kilojoules per kilogram per kelvin.
What is the value of the of gamma in air?
The value of the specific heat ratio (gamma) in air is approximately 1.4 at room temperature. It represents the ratio of specific heats, which is the ratio of the heat capacity at constant pressure to the heat capacity at constant volume.
Specific heat capacity of air?
1000 J /kg-K
How does heat affect air?
Heat causes air molecules to gain energy and expand, leading to decreased density and increased buoyancy. This expansion of air can result in air currents, such as wind, as the warmed air rises and cooler air moves in to take its place. Heat can also increase the air's capacity to hold moisture, which can lead to the formation of clouds and precipitation.
Why does water not heat up or cool off as air?

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.
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 are temperature near the great lakes cooler in the summer than temperatures a few miles away?
The lakes have a high specific heat capacity.Answer:Air passing over the lakes becomes moister from evaporation. This evaporation of water requires heat which is absorbed from the air. As a consequence the air becomes cooler.
What is the Applications of specific heat capacity?
i like to give a short application of specific heast energyland and sea breeze,air conditioners as a coolent, radiators ,
