What happens to air heated by radiation?
When air is heated by radiation, the air molecules absorb the radiant energy and increase in kinetic energy, causing them to move more vigorously. This increased motion leads to expansion of the air, resulting in a rise in temperature.
What happens to liquids and gases as they are heated?
The molecules in side move or spread apart
How does the movement of molecules inside a solid block of iron change as the iron is heated?
As the iron is heated, the kinetic energy of the molecules increases, causing them to vibrate more rapidly and over larger distances. This increased motion disrupts the ordered arrangement of the molecules, leading to expansion of the solid structure as the molecules move further apart.
What happens to water molecules when they are heated?
Like all molecules, a molecule of H20 is in constant motion; 'hot' molecules move faster than 'cold' molecules. If the molecules move slowly enough the substance appears stationary to us (frozen water) and if they move quickly enough they will expand to fill their container (vapor or gas water.)
Why water tends to resist changes in temperature?
Water is highly cohesive. Its molecules tend to resist increases in their motion. When water is heated, some of the energy is used to disturb the hydrogen bonds between neighboring molecules.
What is the movement of molecules as they are heated unevenly called?
Random Motion
What happens to sucrose molecules when heated?
new molecules starts to form
What name is used for the main type of thermal energy transfer that happens when a gas is heated?
The main type of thermal energy transfer that happens when a gas is heated is convection. In convection, the heated gas molecules become less dense and rise, while cooler gas molecules sink, creating a circular motion that transfers heat throughout the gas.
What happens when molecules are removed from heat?
the molecules will decrease in motion
What happens to the molecules of air when they are heated?
they get exited and move faster than cold molecules
What happens to molecules when water is heated from 90 to 110 Celsius?
The liquid molecules are transformed in gas molecules.
What happens to water molecules when water is heated from 90 to 110 Celsius?
The liquid molecules are transformed in gas molecules.
When solid is heated and melts into a liquid what happens to its molecules?
they get farther apart.
What do the lines on a phase diagram present?
what happens to water molecules when they are heated
What happens to a particle when heated?
The magnitude of the vibration of its molecules gets increased.
What happens to the motion of the water molecules as a result?
As a result of WHAT?
What happens to air heated by radiation?
