Does ice melt faster in water or milk?
Ice will melt faster in water than in milk due to the difference in thermal conductivity and specific heat capacity of the two liquids. Water has a higher thermal conductivity and specific heat capacity compared to milk, allowing it to transfer heat more efficiently to the ice and melt it faster.
What is the thermal capacity of air and how does it affect the transfer of heat in various environments?
The thermal capacity of air refers to its ability to store and release heat. Air has a low thermal capacity compared to other substances like water or metal. This means that air heats up and cools down quickly. In environments where air is the medium for heat transfer, such as in convection, the low thermal capacity of air results in faster heat transfer compared to mediums with higher thermal capacities.
What is the definition for thermal energy for kids?
thermal energy is energy in the form of heat.
Does sand absorbed heat faster?
Yes, sand absorbs heat faster than water because it has a lower specific heat capacity, meaning it requires less energy to increase its temperature. Sand can also transfer heat quickly due to its thermal conductivity, making it heat up faster than water which has a higher specific heat capacity and lower thermal conductivity.
What takes more energy to heat?
Water takes more energy to heat compared to air because water has a higher specific heat capacity, meaning it requires more energy to raise its temperature. Additionally, water has a higher thermal conductivity compared to air, leading to faster heat transfer.
Does the temperature of water change more slowly than the temperature of land?
Yes, water has a higher thermal capacity.

Why water is a very efficient thermal buffer?
Water has a high heat capacity, which can be described as "thermal inertia". That means that water can absorb a large amount of heat energy.
A piece of iron and a cup of water both ahave the same temperature If they are heated so the thermal engergy of each doubles?
If the thermal energy of the iron and water doubles, then the temperature of both substances will also increase. Iron has a much higher specific heat capacity compared to water, so the increase in temperature will be more significant for the water than for the iron. However, both substances will experience the same increase in thermal energy.
Why is the temperature of soil higher than the water when heated by the sun?
Soil has a lower specific heat capacity compared to water, which means it heats up faster and to higher temperatures when exposed to the sun. Additionally, soil is less effective at reflecting sunlight compared to water, which also contributes to the soil heating up more quickly.
Why water is used as coolant as well as heater in hot water bags?
Because it has a high thermal capacity.
What is the definition for thermal energy for kids?
thermal energy is energy in the form of heat.
Does water or steel have a higher heat capacity?
Water has a higher heat capacity than steel. This means that water can absorb and store more heat energy without undergoing a significant change in temperature compared to steel. A substance with a higher heat capacity requires more energy to raise its temperature.
Does sand absorbed heat faster?
Yes, sand absorbs heat faster than water because it has a lower specific heat capacity, meaning it requires less energy to increase its temperature. Sand can also transfer heat quickly due to its thermal conductivity, making it heat up faster than water which has a higher specific heat capacity and lower thermal conductivity.
