Which has the greater specific heat capacity- an object that cools quickly or an object of the same mass that cools more slowly?
An object that cools slower has a greater specific heat capacity because Heat capacity is related to a substance's ability to retain heat and the rate at which it will heat up or cool.For example, a substance with a low heat capacity, such as iron, will heat and cool quickly, while a substance with a high heat capacity, such as water, heats and cools slowly. This is why on a hot summer day the water in a lake stays cool even though the air above it (which has a low heat capacity) heats quickly, and why the water stays warm at night after the air has cooled.
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.
Why does heat travel faster by water than by air?
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.
Does water have a relatively low heat capacity?
Water has a relatively high heat capacity, not a low heat capacity. Heat capacity is the amount of heat energy required to raise the temperature of a substance by a certain amount. Water has a high heat capacity because it requires a lot of energy to raise its temperature. This property of water is due to the strong hydrogen bonds between its molecules, which require a lot of energy to break. As a result, water can absorb or release a large amount of heat without undergoing a significant change in temperature, making it an excellent heat sink. The specific heat capacity of water is the amount of energy required to raise the temperature of a substance by 1 degree Celsius (or 1 Kelvin). Water has a high specific heat capacity because it requires a lot of energy to raise its temperature. This property of water makes it an important factor in the regulation of temperature in living organisms and in the Earth's climate. It is also why water is often used as a coolant in various types of cooling systems, such as in car radiators and air conditioners.
Does heat transfer more in water than air?
Yes. Because water has a greater density than air, the energy required to get all particles in the same volume of water in motion is greaty than that of air or another less dense fluid.

What has a greater specific heat capacity air or water?
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.
Does heat have a higher heat capacity than water?
I believe you mean does air have a higher heat capacity than water, maybe? If so, no, water has the higher heat capacity. Water is a very slow to heat substance, this is why after winter, water is still really cold while the air may be even 30C. This property of water helps our planet keep moderate temperatures.
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 water not heat up or cool off 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 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.

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.
Why specific heat capacity of water by experiments is less thanthe actual heat capacity of water?
The specific heat capacity of water is less in experiments is less because heat energy is lost to air and surroundings. The lost energy can me minimised by insulating the container. Class 4.5 St. Davids High School, Dalkieth, Scotland
Which have lowest specific heat capacity?
the lowest heat capacity is either air or land because there's no high capacity on it
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.
