What do you notice about its temperature during boiling?
When a liquid is boiling the temperature stays constant. This is because the heat energy you are adding is being taken away with the vapour being produced.
When energy is added into a liquid what does it become?
Yes Because the liquids molecules have to over come the resistance between each other
What happens to thermal energy when temperatures increase?
When the temperature of a material increase, thermal energy is added to the material. It also increases the kinetic and potential energy of the particles. When the temperature reach the boiling or melting point, the kinetic energy stays the same, but the thermal energy and the potential energy still keeps adding and increasing. And when ONLY the potential energy increase, the state of the material changes from one to another.
Did the temperature fluctuate while the is melting?
No. The temperature does not change during the melting process. All of the heat energy is used to break the bonds of the solid to form a liquid, i.e. the energy is used in the phase change, and thus is not used to raise the temperature.
What happens to energy as it flows through a food chain?
It keeps going until the consumer dies and decomposers take it down or when the food chain is removed or added to. It stays the same as long as nothing eats it
What happens to a substances temperature during a phase change?
stays the same
Temperature is not a measurement of the amount of heat?
True! Temperature is the average kinetic energy of the molecules of a substance.Heat is the total kinetic energy of the molecules of a substance. See the difference?For example, if you double the amount of a substance, then you have double the heat energy, but the temperature stays the same.
As the particles in an object move faster and their average energy becomes greater what is the temperature of the object.?
stays the same
What is the heat energy needed to change a liquid to gas while the temperature stays the same?
(latent) heat of vaporization
When heat is added to a liquid at the boiling temperature it converts the liquid into a gas at the same temperature because?
The additional heat, called "enthalpy" completes the phase change, by changing the arrangement of the molecules in the existing environment, not the temperature. The energy must be removed from a gas to cause condensation into liquid, and from a liquid to cause solidification (freezing). Conversely, it is added when changing a solid to a liquid or a liquid to a gas. At a certain temperature (critical temperature), the process happens spontaneously because the phase boundary disappears.

Does a cloud have potential energy?
No. It either has potential or kinetic 'cause the cloud floats in the sky then it moves sometimes it stays still

And when ONLY the potential energy increase, the state of the material changes from one to another.
Is it possible to add thermal energy to a substance and not to raise its temperature?
Thermal energy is simply just another term for temperature. Adding thermal energy to any substance will always create a rise in temperature. The only way it would be possible to add thermal energy to a substance without seeing any net increase in temperature would be if the substance lost an equal amount of thermal energy at the same time.Answer:At the melting point and boiling point any input of thermal energy goes to the change of state rather than the rise in temperature. As a consequence boilling water stays at 100oC until it is all evaporated and melting ice stays at 0oC until the entire mass is melted
What is is kinetic energy?
Energy stays Kinetic.
Did the temperature fluctuate while the is melting?
No. The temperature does not change during the melting process. All of the heat energy is used to break the bonds of the solid to form a liquid, i.e. the energy is used in the phase change, and thus is not used to raise the temperature.
