Yes. For an ideal gas the internal energy which is a combination of both Kinetic(K)and Potential(U) energy is related to temperature in the following way.
E = K+U = 3/2 * R * T
However since there is no particle integration in an ideal gas the potential energy is 0 thus:
E = K = 3/2 *R*T => K ~ T
So the kinetic energy of the system is directly proportional to the temperature. If T goes up, so does K.
when there is coland warm air the warm air is going to like eat all the cold air up so there is no cold air at all........................................
hope that will help you

The amount of energy to heat a substance will depend on:
* The mass of the substance
* How many degrees you want to heat it
* The heat capacity, which you can think of as a kind of "thermal inertia", which varies depending on the substance
because the particles change more heat energy they receive into kinetic energy of the particles
You have it slightly backwards. Something that has more thermal energy is
often, but not always, hotter than something that has less thermal energy.
Burn substances and measure the enthalpy (energy released) to determine their energy content.
because the electrons are flowing faster and looking for things to hit and react with
The particles vibrate more rapidly. They push each other further apart so that the substances takes up more space.
Objects moving against the force of friction dissipate energy in form of heat. Some part of this heat, is absorbed by the body itself and objects get warm.
You calculate the kinetic energy of two objects, then compare.
You need to take heat energy out of the substance.
Light energy is converted into heat energy when plants take in sunlight (light energy) and convert it into heat energy when they respire and produce energy.
As energy increases molecules begin to move faster and shake more vigorously if you take energy out molecules do the opposite.
Chemical energy> Thermal(Heat) energy Heat energy> Rotating mechanical energy

You need to take heat energy out of the substance.
The higher the substance's specific heat capacity, the more heat energy is needed to raise it's temperature.
The specific heat of a substance allows us to calculate the amount of heat energy required to change its temperature. Water has a specific heat nearly 11 times great than copper, therefore, water will take 11 times more energy to heat. Also water heats slowly and copper heats and cools rapidly.
When a substance changes from a liquid to a solid it releases energy. (You take the heat out)
The basic formula which describes the energy required to raise the temperature of a substance is ΔE=mcΔθ. where: ΔE = Difference in energy m = mass of the substance c = specific heat capacity of the substance Δθ = change in thermodynamic temperature without any calculation, it is clear that if the change in temperature is the same (i.e. from room temperature to boiling point); and the specific heat capacity is the same; the more of the substance that is being boiled; the more energy is required. If the device which is boiling the substance is at a constant power, whether it be a burner or a kettle, the more energy required to boil the substance, the more time it will take to boil so long as the power is held constant.
Heat is a measurement of the amount of motion (or kinetic energy) of the particles of which a given substance is composed. In a solid, this motion is just a vibration, since the particles remain in place. When particles vibrate more, they will take up more space. In a gas, the particles move independently of each other, and if they move faster, they will exert more pressure and thus will tend to expand.
Substances may contain more elements than the other substance, meaning that it would take more energy (heat) to break the bonds of the substance as opposed to the other substance. Because these bonds must break in order to change phases, it would take more energy to dismantle the larger substance. Another thing that affects melting points is the types of bonds that connects the atoms to each other. Double bonds take more energy to break than single bonds. Triple bonds take more energy than double bonds so that could also account for the differences in melting points between two substances.
A substance's molar specific heat capacity is the amount of energy required to raise one mole of that substance 1 degree Celsius.For water, this is exactly one calorie, assuming the state of the water does not change. Otherwise, it depends on the substance, and the substance's current temperature and state.for apex its latent
No, heat energy depends on the amount of substance. You have asked a very good question that confuses many. Heat energy is different from temperature.If the temperature of Lake Michigan is 60 degrees, I can take ashot-glass of water out of the lake and carry it over to my car, and the temperature of the water in the shot glass is still 60 degrees.However, there is an enormously vastly larger amount more heat energy in Lake Michigan than the shot glass. One could heat up the shot glass with the heat energy from a candle in a minute, but it would take trillions of candles to heat Lake Michigan the same temperature difference in that minute.
Type your answer here... A substance with high specific heat means it can absorb alot more heat energy before its temperature increases. A substance with low specific heat cannot absorb alot of heat energy so its temperature increases quickly because it cant absorb the heat. Remember there is a difference between Heat energy and Temperature. The ocean can absorb alot of heat energy but still feel like its cold in temperature. The tip of a needle can be at 1000 degrees temperature but there is hardly any actual heat energy in it because its so small.
When energy (in this case, heat) is added, it excites the molecules and causes them to begin to move more. This extra movement causes them to repel one another more, causing the substance to take up more space.
Hydrogen bonds are strong, such as in water. Therefore it take more energy (heat) to bring it to a boiling point (break or weaken the bonds so they are more freely moving as in a gas). Therefore it has a larger heat capacity. The above answer, while mostly correct, is wrong in relating the boiling point of a material to its heat capacity. Heat capacity is a measure of how much energy it takes to increase a specific amount of a substance by 1 °C. It doesn't have anything to do with phase changes as implied by the answer above. The heat capacity of a substance is generally a function of the number of degrees of freedom of the molecule. Larger molecules have more degrees of freedom than do smaller molecules. Heat capacity has to do with how well molecules are able to store (or trap) energy. This can be in translational energy, molecular vibrations and molecular rotations for instance. Hydrogen bonds provide another way for energy to be stored. As heat is added to the substance, some of that energy goes into breaking the bonds rather than simply raising the temperature. The more places a molecule has to deposit energy (degrees of freedom), the higher the heat capacity. See the Wikipedia link to the left for more information.
