Why evaporation happens at the surface?
When water molecules at the surface gain sufficient energy they can escape in the atmosphere. Evaporation (not vaporization) occur at any temperature; a higher temperature increase the rate of evaporation. The energy of water molecules increase by a temperature increase and some molecules at the surface can escape in the atmosphere.
What happens when the temperature of a gas increased?
If you increase the temperature of a gas, its particles (atoms or molecules) will speed up. If it is in a closed container, the pressure will also increase.
What happens when water absorbs an IR photon?
When water absorbs an infrared (IR) photon, the molecular vibrations of the water molecules increase as they absorb the energy from the photon. This increase in vibrational energy causes the water molecules to move more vigorously and increase in temperature.
If you increase the temperature of a gas what happens to the movement of the molecules?
Increasing the temperature of a gas causes the molecules to move faster on average, which leads to an increase in their kinetic energy. This results in more frequent and higher energy collisions between the molecules.
What happens to the movement of molecules when their temperature is?
As the temperature is lowered, the movement of the molecules decreases.
What best explains what happens when liquid water evaporates to form water vapor?
When water molecules at the surface gain sufficient energy they can escape in the atmosphere.The energy of water molecules increase by a temperature increase and some molecules at the surface can escape in the atmosphere.
What happens to the speed at which molecules are moving?
The speed at which molecules are moving increases as temperature increases, since temperature is a measure of the average kinetic energy of the molecules. This leads to an increase in the rate of collisions between molecules and an increase in the overall kinetic energy of the system.
What does a temperature increase cause the rate of a reaction to increase?
As temperature increase the speed and energy of molecules increase and the collisions are more probable.
What happens to molecules as energy is added and the temperature increases?
As energy is added and temperature increases, molecules gain kinetic energy and move more rapidly. This increase in movement can lead to stronger molecular interactions, changes in molecular configuration, and ultimately a change in the state of matter (e.g., from solid to liquid or gas).
How does temperature increase cause the rate of reaction to increase?
The movement of molecules and collisions are increased at high temperature.
When a closed can is heated the pressure inside. this happens when?
When a closed can is heated, the molecules inside the can gain energy and move faster, leading to an increase in pressure. This happens because the increase in temperature causes the molecules to collide more frequently with the walls of the can, exerting more force and increasing the pressure inside.
What happens to the gas molecules when the temperature is increased?
When the temperature is increased, the gas molecules gain kinetic energy and move faster. This causes them to collide more frequently with each other and the container walls, resulting in an increase in pressure and volume.
