What molecular changes happen when thermal energy is added or removed from nitrogen?
When thermal energy is added to nitrogen, the molecular motion increases, causing the molecules to vibrate and move more rapidly. This results in an increase in temperature. When thermal energy is removed, molecular motion decreases, leading to a decrease in temperature. The phase of nitrogen may change depending on the temperature, transitioning between solid, liquid, and gas states.

Does sulfur conduct thermal energy?
Yes, sulfur is a poor conductor of thermal energy. This is because its molecular structure does not allow heat to transfer easily through the material.
The gas liberated when ammonium dichromate undergoes thermal decomposition?
The gas liberated when ammonium dichromate undergoes thermal decomposition is nitrogen gas (N2) along with water (H2O) vapor and chromium(III) oxide (Cr2O3) solid residue.
What is the best insulator of heat nitrogen or alcohol?
Nitrogen is a better insulator of heat compared to alcohol. This is because nitrogen is a gas and has lower thermal conductivity than alcohol, which is a liquid. Nitrogen can create a barrier that inhibits heat transfer more effectively than alcohol.
Which of these is the best insulator of heat water or nitrogen?
Nitrogen is a better insulator of heat than water. This is because nitrogen is a poor conductor of heat due to its low thermal conductivity compared to water. In terms of insulation properties, nitrogen would be more effective in retaining heat or keeping out cold compared to water.
A complete absence of thermal energy?
A complete absence of thermal energy would result in absolute zero temperature, at which point all molecular motion ceases. This state cannot be achieved in practice, as even in the coldest environments there is still some residual thermal energy present.
When thermal energy is added or removed particle motion changes?
When thermal energy is added, particles absorb the energy and their motion increases, leading to higher temperatures. Conversely, when thermal energy is removed, particles lose energy and their motion decreases, causing a decrease in temperature. This relationship between thermal energy and particle motion is described by the kinetic theory of matter.
How are states of matter and changes in energy related?
When thermal energy is added or removed, the state of matter changes to another eg. solid becomes liquid and liquid becomes gas.
How is molecular weight and thermal stability related?
They are not related. Thermal stability depends much more on the nature of the bonds in the compound, not the molecular weight.Boiling and melting points do generally reflect molecular weight (both go up with increasing mass), but thermal stability usually refers to chemical decomposition rather than physical changes such as melting or boiling.There are very light and very stable compounds (carbon dioxide is one), and there are very big and stable compounds (polymers), and there are very light unstable compounds (hydrogen gas) and very heavy unstable compounds (TNT isn't huge, but fairly large...).
What can changes in thermal energy can be measured with?
Changes in thermal energy can be measured with a thermometer, thermocouple, infrared camera, or a calorimeter. These tools can detect changes in temperature or thermal radiation, allowing for quantitative measurements of thermal energy.
What is a thermal energy of a substance?
the total energy from molecular motion.
What is the relationship among heat and thermal energy?
Heat is the transfer of thermal energy between objects due to a temperature difference. Thermal energy is the total kinetic energy of particles in an object and is what determines its temperature. When heat is added or removed from an object, it changes the thermal energy and consequently the temperature of the object.
What is the ability to hold heat called?
The ability to hold heat is called thermal inertia. This is the capacity of a material to resist changes in its temperature when heat is added or removed. Materials with high thermal inertia can maintain their temperature for longer periods of time.
What form of energy changes water from liquid to gas?
Thermal Thermal
What energy transfer does making pancakes in a frying pan use?

What happens if you remove thermal energy from a liquid?
If thermal energy is removed from a liquid, its temperature will decrease, causing it to eventually solidify if enough thermal energy is removed. The speed at which this occurs depends on the specific properties of the liquid.
Do sulfur nitrogen phosphorus and bromine have the same thermal conductivity?
These elements have quite different physical characteristics. At normal temperatures and pressures, nitrogen is a gas, sulfur and phosphorus are solid, and bromine is a liquid. Nitrogen, in a gaseous state, is far less thermally conductive than the others.
Does wind have thermal energy?
yes. everything has some thermal energy. Even liquid nitrogen has some thermal energy. Nothing can have no thermal energy, look at the 3rd law of thermodynamics.
