Hydrogen bonds
Hot water is hot because its molecules have a higher amount of thermal energy compared to cold water. This thermal energy causes the molecules to move faster and collide more frequently, resulting in a higher temperature. In practical terms, hot water is typically heated by a heat source such as a stove, kettle, or water heater.
When a drop of water falls on a hot stove, it instantly vaporizes due to the high temperature of the stove. The water droplet transforms into steam, which rises quickly into the air.
Yes, boiling water in a pot on a stove creates water vapor. As the water boils, it transitions from liquid to gas form, producing steam or water vapor.
You can use a stove, electric kettle, or microwave to boil water. Each method has its own advantages in terms of speed and convenience.
The water will evaporate quickly due to the heat of the stove. It may sizzle or produce steam upon contact with the hot surface. If the stove is extremely hot, the water may even evaporate before making direct contact.
The force of atmospheric pressure makes it harder to boil water on a stove because it pushes down on the water's surface, increasing the boiling point. This means the water needs to reach a higher temperature to overcome the pressure and boil.
It can be harder to boil water on a stove at higher altitudes because the air pressure is lower, resulting in lower boiling point of water. This means that the water requires more heat energy to reach its boiling point compared to at sea level.
because the density of the water makes the velocity of the material equal to the tensile strength which makes a chemical reaction causing the metal to be harder
Water or steam? It makes a difference.
I don't see how magnetism would make any significant difference.

g-force
The force that makes it hard to wade through water is drag force. Drag force is the resistance that water exerts on an object moving through it, which increases with the object's speed and surface area. This force makes it feel like you are pushing against the water as you wade through it.
By paddling harder.
The Glass is so hard to push underwater because air has less density than water, so it floats. This causes the glass to have an air bubble inside of it, thus making the glass harder and harder to push down.
An example of fluid friction is when a swimmer experiences resistance as they move through water. The water molecules come in contact with the swimmer's body, causing a drag force that makes it harder for them to move forward smoothly. This frictional force acts in the opposite direction to the swimmer's motion.
The force that causes objects to float on water is buoyancy. Buoyancy is the upward force exerted by a fluid (in this case, water) that opposes the weight of an object placed in the fluid. If the buoyant force is greater than the weight of the object, the object will float.
