Put simply, it means that it takes a greater amount of energy to raise the volume of a substance (e.g. 1cc water) than is does a comparable substance. Water, life giving substance that it is, it beautifully constructed for this purpose.

Why does water stay cooler than land?
The thermal capacity is higher for water than land, therefore the land is able to cool faster than the water. The water takes a longer time to heat up and cool off than the land.
What high tide mean?
it means that the water is at a high level. the ocean will be closer to you where as a low tide is the opposite and it will be further away
What do the H and L mean on a weather map?
H means high pressure and L, low pressure.
What does the tide is high mean?
it means that the water is at a high level. the ocean will be closer to you where as a low tide is the opposite and it will be further away
What happens to the temperature of boiling water if you turn up the heat on the stove?
The boiling point of water is 100 degrees celsius. The water will evaporate at boiling point. By the way what do you mean "what happens to the temperature of boiling water" if you think about it, it does not make sense.
How does ice cool?
Water have a very high heat capacity and that mean water can contain a lot of heat which resulted in the cooling effect. Remember ice is water in solid form.
What does it mean to say that a material has a high or low specific heat capacity?
The specific heat capacity of a substance is the amount of energy required to increase the temperature of a said substance 1o K. The capacity is measured in kilojoules divided by kilogram time degrees Kelvin (kJ/Kg k). So, if the specific heat capacity of a substance is high, it requires a very large amount of energy to increase the temperature, and if it has a low specific heat capacity, the required energy will be lower.

It influences the amount of heat needed for matter to reach a certain temperature when a substance expands or contracts however it does not change what is it?
I guess you mean the specific heat capacity of a substance. Water is 1 calorie per gram, for other substances the quoted figure is often called the 'specific heat' which just means the ratio of its own heat capacity to that of water.

What late heat mean in HVAC?
All 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.
Why does water have a high specific heat capacity?
Water has a high specific heat because of the hydrogen bonds acting on the molecules. These hygrogen bonds can "store" thermal energy, and this allows water to absorb or release a lot of heat without a large change in temperature.
Why would the tea in a teacup and tea in a teapot be the same temperature even though the teapot holds more?
large heat capacity do not mean high in temperature. Both may have the same temperature but obviously the teapot has higher heat capacity compared to teacup as the teapot contain more than the teacup.Remember that heat capacity is directly proportional to the mass.
Does a high or low specific heat mean the substance heats up so fast?
low specific heat is like sand and high specific heat is like water at the beach it may be hot outside the water is still cold but the sand is hot as ever.
Why do you get chills after heat exhaustion?
Typically chills mean water is evaporating on your skin from sweat, but it can sometimes mean that your core temperature is too high and your body is having trouble regulating it. This can be a symptom of heat exhaustion or heat stroke.
What the mean by hbc fuses?
High Breaking Capacity
What is a specific heat of land?
Air has a heat capacity of 1007 J/(kg K).Water has a heat capacity of 4218 J/(kg K).There is approximately a factor of four difference. When comparing the effective heat capacities of a column of air and a column of water, the relative masses of the columns must be considered; A column of air extending to mean sea level (no topography) has a mass of 10^4 kg / m^2 (surface pressure divided by gravity). Thus a column of atmosphere has a heat capacity of about 10^7 J/m^2. The same mass is found in 10 meters depth of water. Thus, a column of water has a heat capacity of 4*10^7 * (depth / 10 m) J/m^2. Thus, when comparing the heat capacity of a water column and an air column, there is a factor of four difference for the heat capacity and a factor of water depth / 10 meters for the masses. For example, a 50 meter column of water (typical mixed layer depth) has 4*50/10 = 20 times that of air. I would love to know some values for the land surface... that's how I ended up here.
