What else can I help you with?
What happens to a suspension if it is left to sand?
the sand dissolves in the water
How is heat transferred to the sand on a beach?
The energy from the Sun adds energy to the molecules of the outermost layer of sand, which radiates infrared energy and also conducts thermal energy down into the sand.
What hold heat longer the sand or water?
Sand typically holds heat longer than water because sand has a lower heat capacity than water, meaning it requires less energy for its temperature to increase. This allows sand to retain heat for a longer period of time compared to water, which has a higher heat capacity and can lose its heat more quickly.
Does sand transfer heat?
Yes, sand can transfer heat. It is a good conductor of heat, meaning it can absorb and transfer heat energy relatively well compared to materials like ice or wood. This is why sand can feel hot to the touch when exposed to sunlight for a period of time.
The fact that desert sand is very hot in the day and very cold at night is evidence that sand has a low specific heat capacity or high specific heat capacity?
High specific heat capacity, because it takes a significant amount of heat energy to raise the temperature of sand during the day, and that heat is released slowly at night, resulting in the temperature drop.
If you place a cup of sand and a cup of water in the sun which one will heat up faster?
The cup of water will heat up faster than the cup of sand because water has a higher specific heat capacity, meaning it requires more energy to increase its temperature compared to sand. Sand, being a solid, has a lower specific heat capacity and will heat up more quickly.
How is specific heat related to thermal heat?
specific heat is the amount of thermal energy needed to raise the temperature of an object. for example, the water on the beach and the sand on the shore are absorbing the same amount of thermal energy from the sun but the water (which has high specific heat) is cold, and the sand (with low specific heat) is very hot.
When bullet penetrates into bag of sand what type of energy it exert?
The kinetic energy of the speeding bullet is converted to heat and sound energy.
What kind of heat causes the sand to get hot?
Sand gets hot primarily due to direct sunlight and absorption of solar radiation. The particles in the sand absorb the sun's energy, which causes them to vibrate and generate heat. Additionally, sand can retain and release heat well due to its thermal properties.
Is the sand on a beach gets hot from the sun endothermic or exothermic process?
Endothermic. The sand is absorbing heat. If it was radiating heat, that would be exothermic.
What kind of heat transfer is burning your bare feet on hot sand?
The heat transfer is primarily through conduction, as the hot sand comes in direct contact with your bare feet and transfers heat energy to them. Additionally, there may also be some heat transfer through radiation from the sand to your feet.
What holds heat longer soil or sand?
Soil tends to hold heat longer than sand due to its higher specific heat capacity and thermal conductivity. This means that soil can absorb and store more heat energy, making it warmer for a longer period compared to sand.
