Explain how water can transfer energy by conduction and by convection?
In conduction, water molecules pass energy through direct contact with neighboring molecules, transferring it without moving the water itself. In convection, energy transfer occurs through the movement of water molecules, as warmer water rises and cooler water sinks, creating a circulation pattern that distributes the energy throughout the water body.
Why cant cold water blow up a balloon?
Cold water is denser than warm water, so when a balloon is submerged in cold water, the pressure from the water isn't enough to inflate the balloon. The molecules in cold water are also less energetic, which means the molecules won't exert enough force to inflate the balloon.
Why cant water pass through a solid rock?
Water cannot pass through a solid rock because the rock's structure is tight and does not have spaces for the water to flow through. The pores in the rock are too small for water molecules to move through.
Explain how microwave ovens are able to cook food using the idea of resonance?
Microwave ovens cook food by generating electromagnetic waves that cause water molecules in the food to vibrate, generating heat. This process is based on the principle of resonance, where the frequency of the microwaves matches the natural frequency of water molecules, leading to their absorption of energy and heating up the food.
Why cant you see a laser beam if its in pure water?
You can't see a laser beam in pure water because the water is transparent, which allows the light to pass through without scattering. This means that the laser beam doesn't interact with the water molecules in a way that makes it visible to the human eye.
What are the factors infuencing the absorded water films on the particles?
First of all water isn't absorbed by particles. The water molecules tend to stick around other particles because the surface tension of the water molecules cant balance the force of attraction between the water molecules and the molecules of the particle.
What happens to the molecules if they freeze?
well obviously atoms cant stop moving even at absolute 0. so the molecules will simply slow down but it can never stop moving
Why cant salt dissolve in water?
it can, polar water molecules easily dissolve polar molecules, or ionic compounds such as salt.
Explain how water can transfer energy by conduction and by convection?

In convection, energy transfer occurs through the movement of water molecules, as warmer water rises and cooler water sinks, creating a circulation pattern that distributes the energy throughout the water body.
Why cant water be infinitely divided?
Water consists of water molecules, consisting of two hydrogen atoms and one oxygen atom. Once it's down to molecules, it won't be water anymore if you split the molecules up.
Why cant stones float in water?
The molecules in a stone are packed together more tightly than the molecules in water-- the stone is more dense than the water is, so the stone sinks.
Why cant marine animals break down water molecules into oxygen?
Marine animals do not break down water molecules into oxygen, just like we don't. They breathe O2 gas that is in solution in the water.
Does slow moving water cause erosion or fast moving water?
yes and no well it cant cause fast water and it will weather slower then as if water would at a fast current so it will weather just slow.
Why water cant mix with lipids?
Lipids are fat molecules, like solid oils. They contain lots of carbon atoms, so they cannot dissolve because the molecules do not break apart in water.
Why jewelry cant be wore around forklift?
Jewelry and loose, long hair is dangerous on any machinery with moving parts.
What kinds of substances cant be dissolved in water?
Substances that cannot be dissolved in water are typically nonpolar molecules, such as oil, fats, and wax. In general, substances with strong intermolecular forces that are not easily disrupted by water molecules will not dissolve in water. Examples include hydrophobic molecules like hydrocarbons and certain gases like oxygen and nitrogen.
Why cant sound travel from planet to planet?
Because space is a Vacuum, there are not enough gas molecules around to transfer the sound waves.
