if steam and water are both at 100 degrees celsius, why would the steam scald you more, even if they both have the same kinetic energy?
Steam has more energy than water because it takes energy to break the bonds that keep it a liquid. When steam hits you, some of it condenses, and your skin absorbs all that extra energy.daveed said:if steam and water are both at 100 degrees celsius, why would the steam scald you more, even if they both have the same kinetic energy?

When a specific mass of water reaches 100C, it isn't even close to having enough energy for all of it to turn to steam. It takes 539 cal/gram to boil water that is already at its boiling point, but to raise it one degree C (to get to the boiling point) only takes 1 cal/gram.Dual Op Amp said:Once water reached it's evaporation point, it changes into steam, and floats away into the air.

Steam and water at the same temperature are both forms of water, but they have different physical properties. Steam is the gaseous form of water, while water is the liquid form. Steam is created when water is heated to its boiling point and evaporates. Water, on the other hand, remains in its liquid state at the same temperature.
No, steam and water at the same temperature do not have the same energy content. Steam has a higher energy content because it requires more energy to convert water into steam. This process is known as the latent heat of vaporization. Therefore, even though steam and water may be at the same temperature, steam has more energy stored within it.
Both steam and water at the same temperature can be dangerous in their own ways. Steam can cause burns and scalding due to its high temperature, while water can cause drowning or hypothermia if it is too cold. However, in terms of heat transfer, steam is more dangerous as it has a higher heat capacity and can transfer heat more quickly than water.
Yes, steam and water at the same temperature can coexist under certain conditions. This is known as saturation or equilibrium. At this point, the rate of water molecules evaporating and steam molecules condensing is equal, resulting in a balance between the two forms of water. However, any change in temperature or pressure can disrupt this equilibrium.
When steam and water at the same temperature are mixed, they will reach a new equilibrium state. Some steam will condense into water, while some water will evaporate into steam until the new equilibrium is reached. This process is known as condensation or evaporation, depending on the direction of the change in state. The resulting mixture will have a temperature lower than the initial temperature of the steam, but higher than the initial temperature of the water.
