Water is made of tiny pieces called molecules. Heat makes molecules excited. They jump around and move quickly! They need space to do this. Cold, on the other hand, makes molecules slow down and it can make them nearly stop. They don't need as much room to move around and the space between them shrinks! It would seem that cold water would have to be denser than warm water.
What else can I help you with?
Is hot air liter or heavier than cold air?
Hot air rises, so is lighter than cold air.
Can a hot water heater siphon to cold water faucet?
A hot water heater is designed to supply hot water to faucets, not cold water. It is not possible for a hot water heater to siphon into a cold water faucet. Each faucet is connected to either the hot or cold water supply lines, which are separate in a plumbing system.
When you add hot water to cold eater the cold water warms up because of?
When you add hot water to cold water, the cold water warms up because of thermal conduction. Some of the kinetic energy of the hot water transfers to the cold water on contact, eventually leading to a uniform temperature throughout.
Is statch more soluble in hot or cold water?
hot water
What happens if you drink cold water mixed with hot water?
When hot water and cold water are mixed together, heat flows from hot water to cold water and brings them to equilibrium at a temperature intermediate to that of hot water and the cold water That may be right, but I think that the hot water would be more dominant causing the cold water to almost instantly turn hot.
What is heavier hot or cold water?
lil Wayne
Why is hot water havier then could water?
You are wrong ! - Cold water is heavier ( denser ) than hot water.
What happens when hot water meets cold water?
cold water is much heavier than hot water . the water becomes warm
What is the heavier molecule hot or cold?
Hot is the heavier molecule.
Why hot water is heavier than cold water?
Given an identical volume of both to begin with (say, one gallon hot water, and one gallon cold water) they will be identical in weight. However, cold water is more dense than hot water.
How does hot and cold water separate?
Hot and cold water can separate due to differences in their temperature and density. When hot and cold water are combined, the hot water tends to rise to the top because it is less dense than the colder water below. This process is known as thermal stratification.
Why does cold water sink when poured OK into hot water?
When cold water is poured into hot water, it sinks because it is denser than the hot water. The cold water is heavier due to the molecules being closer together at a lower temperature, causing it to sink to the bottom. The hot water, which is less dense, rises to the top.
Which water is heavies - hot or cold?
Hot water is less dense than cold water. So if you have equal volumes of both,then the cold one is heavier than the hot one.* That's why we build stoves in such a way as to heat the bottom of the pot ...that's where the colder liquid is.
Is it true that cold water is hot?
No, cold water is not hot. Cold water is at a lower temperature than hot water.
Does the temperature change the density of water?
Yes. Cold water is slightly heavier than hot water. (That's why stoves are built to heat the bottom of the pot, not the top.)
Is water hot or cold?
Water can be either hot or cold depending on the temperature. Water at room temperature is considered neither hot nor cold.
Is Warm air heavier or cold air?
Cold air is heavier than warm air because cold air has higher density. This is because the molecules in cold air are closer together, leading to a greater mass per unit volume compared to warm air.
