What happens to thermal energy in beakers as water cool down to room temperature?

The water in the beakers cooled down which means the particles slowed their vibrating because they had less energy, and the thermal energy turned into a gas because it had so much energy from the heat that it escaped the beaker as a gas.
This is very wrong:
Point 1:
Particles do not slow their vibrations, they are not alive or have any will.
They slow because they collide with the cooler, slower moving air particles around them. The air particles leave a collision moving a little faster (hence the air has got a little warmer) and the water particles leave a collision moving a little slower (hence the liquid has got a little cooler). If you add up the total momentum (velocity x mass) of all particle before a collision and then after a collision the two values will be the same. It is conserved, So two particles colliding with each other cannot overall have more momentum, hence both the liquid and the air cannot simultaneously get warmer or cooler.
Point 2: Energy is not a gas.
A gas is made up of particles that are vibrating faster relative to the corresponding liquid. They are vibrating so fast that they break the interactions that held them close in the liquid form. There is lots of space between the particles in a gas which means you can compress a gas but not a liquid.
Energy is a theoretical concept. Energy is a number that you can calculate from the properties of a closed system. You can then change the system and recalculate. and you will end up with the same number,
Using our three beakers example: Imagine the planet earth is a sealed box, nothing in nothing out not even light (a closed system). On our planet we have our three beakers with hot water and the air around them. I carry out an energy calculation on everything in the sealed box, it adds up to say 100. The beaker is then allowed to cool down, I then carry out the energy calculation again and end up with the same number 100. This number is just a number it doesn't tell us what happen in the physical world it just tells that the total will always be the same in a closed system.

True or false To maintain your body temperature your body converts chemical potential energy into thermal energy?
It is true that to maintain your body temperature, your body converts chemical potential energy into thermal energy. Thermal energy is energy that comes from heat.
The higher the temperature of something the greater its?
Thermal Energy.
Does temperature have an effect on the amount of thermal energy in a substance?
When the temperature might be increasing, thermal energy is increasing and it increases much faster when decreasing than when increasing so it's permanent energy and can never be reducing!
2 glasses of water have the same thermal energy must they have the same temperature explain?
How you can tell is the temperature between the two liquids. If one of the liquid's temperature is warmer than the other one, then that liquid has more thermal energy.
What happens when a solid gains energy?
When a solid gains thermal energy, its atoms and/or molecules begin to move (vibrate) faster and faster as the temperature continues to increase. Eventually, the particles that make up the solid will gain enough thermal energy in order to separate into a liquid through melting or into a gas through sublimation.
When thermal energy is removed from matter what happens to its temperature'?
it is hot temperature but when thermal energy leaves the temperature is cool
What happens to the thermal energy of a substance as its temperature increases?
When a sample of a substance absorbs thermal energy, its temperature rises.
What happens to an object temperature when it loses thermal energy?
Its temperature falls.
What happens to energy used for maintaining body temperature?
Thermal Energy
What happens to the thermal energy of an object as its temperature rises?
it gains more energy
What happens to thermal energy of an object as it's temperature rises?
it gains more energy
What happens to thermal energy in beakers as the water cools down?
due to convection, the movement of energy through a fluid or air, and also the first law of energy conservation, the thermal energy has convects throught the air to cooler regions, therefore cooling the beaker
What happens to a gas's thermal energy as that gas's temperature increases?
It increases.
When there is more kinetic energy what happens to the thermal energy and temperature?
Molecules with a high temperature typically have a greater kinetic energy when compared to those with a lower temperature
When a substance changes state what happens to its thermal energy?
Changes the temperature of the substance
How are thermal energy and temperature similare?
Temperature is what is used to measure thermal energy The more thermal energy a substance has, the more warmer it will be. So when the temperature is high, there is a lot of thermal energy Thermal energy is just energy. It refers to the energy of the molecules. Temperature is just a measurement
How is thermal energy and temperature same?
They are not the same. "Thermal energy" is the same as "heat".
