hot water har less volume n surface area than hot air

Hot water has higher specific heat capacity compared to air, meaning it can store more heat energy. This results in hot water having more potential to transfer heat to the body upon contact, causing burns. In contrast, hot air has lower specific heat capacity and cannot transfer heat as effectively as water, making it less dangerous at the same temperature and mass.

How does the temperature of water affect the time it takes to freeze an ice cube?
Mass holds temperature--the more mass, the better it holds temperature...but, conversely, the longer it takes to get it to temperature all the way through.
How would bigger mass in the water affect the cooling rate?
A bigger mass of water would generally cool more slowly as compared to a smaller mass of water. This is because it takes more energy to lower the temperature of a larger quantity of water. Additionally, larger volumes of water have greater thermal inertia, meaning they resist changes in temperature more effectively.
What two factors are most significant in creating a dense mass of ocean water?
The two most significant factors in creating a dense mass of ocean water are low temperature and high salinity. Cold water is denser than warm water, while high salinity increases the water's density by adding more dissolved salts.
What substance would absorb the most heat energy with the least change in temperature water or copper?
Copper would absorb more heat energy with less change in temperature compared to water due to its higher specific heat capacity. This means that copper can absorb more heat per unit mass before its temperature noticeably increases, while water's temperature would rise more easily when absorbing heat.
Does the temperature of the water affect the density of the ketchup packet?
Yes, the temperature of the water can affect the density of the ketchup packet. When the water is cold, the ketchup inside the packet may become more viscous and slightly denser. Conversely, in warm water, the ketchup may become less viscous and slightly less dense.
What causes a more severe burn - water or steam?
Steam is more dangerous because the temperature is higher.
Does the mass of water affect temperature rise?
No, the mass of water does not affect the temperature rise when applying a fixed amount of heat. The temperature rise depends on the amount of heat energy transferred to the water, not the mass.
How does the temperature of water affect the time it takes to freeze an ice cube?
Mass holds temperature--the more mass, the better it holds temperature...but, conversely, the longer it takes to get it to temperature all the way through.
Which do you think contains more internal energya teaspoon of boiling water or a pan full of water at 50c?
A pan full of water at 50°C contains more internal energy than a teaspoon of boiling water because internal energy is related to both temperature and mass. The pan has more water (greater mass) at a lower temperature compared to the boiling water, so it would have more total internal energy.
What is the difference if any of volume to mass ratio of warm and cold water?
The volume to mass ratio you speak of is usually called density, "density = mass / volume"The density of water does change a little bit depending on the temperature. According to Wikipedia, the density decreases as temperature increases, meaning that the same mass of water takes up less space at a higher temperature. Check out the details and values on Wikipedia for more information.
How would bigger mass in the water affect the cooling rate?
A bigger mass of water would generally cool more slowly as compared to a smaller mass of water. This is because it takes more energy to lower the temperature of a larger quantity of water. Additionally, larger volumes of water have greater thermal inertia, meaning they resist changes in temperature more effectively.
Does the amount of water in a hot-water bottle determine the amount of time that the water stays hot?
Yes, the amount of water in a hot-water bottle affects how long it stays hot. More water retains heat for a longer period of time because there is more mass to keep warm. Conversely, less water cools down more quickly due to less thermal mass.
Is a chemical more dangerous when dissolved by water or is it less dangerous when it cannot?
Generally water-soluble chemicals are more easily absorbed in your body and thus could be more likely to be dangerous to you

Which do you think contains more internal energy a teaspoon of boiling water or a pan full of water at 50 C?
A teaspoon of boiling water contains more internal energy than a pan full of water at 50 C.
Why does water depth effect the water temperature?
Water depth affects water temperature because deeper water is less influenced by changes in air temperature than shallow water. Deeper water has more mass and can retain heat better, leading to a more stable temperature compared to shallow water which can heat up or cool down more quickly. Additionally, sunlight penetration is reduced in deeper water, limiting the amount of heat absorbed at the surface.
What substance would absorb the most heat energy with the least change in temperature water or copper?
Copper would absorb more heat energy with less change in temperature compared to water due to its higher specific heat capacity. This means that copper can absorb more heat per unit mass before its temperature noticeably increases, while water's temperature would rise more easily when absorbing heat.
