What is the relationship between energy and temperature change?
When heat is transferred in a space the average energy of the particles - the temperature of the substance - is affected, by increasing or decreasing. The change in temperature depends on the number of particles affected.
What is a measure of the energy of motion of particles in a substance?
Temperature is a measure of the energy of motion of particles in a substance. It provides information about how fast the particles are moving within the substance.
When heat is added to or removed fron the substance and the temperature remains the the smae where is the thermal energy going?
When heat is added to or removed from a substance and the temperature remains the same, the thermal energy is being used to cause a phase change within the substance. This means that the added heat is causing the particles within the substance to change their arrangement or state of matter, rather than increasing their kinetic energy and raising the temperature.
Why does temperature stay the same during a phase change?
The temperature, in Physics, means the measure of Kinetic Energy in a substance. When a substance is either heated or cooled, Kinetic Energy is either being added to taken away from the substance. When the amount of KE in the substance changes, the temperature change. However, when the substance is changing its state, because all the KE change in the substance is being used up to change the state, the temperature will not change. When the substance is changing state, the KE can be measured by calculating the heat of fusion and heat of vaporization.
What happens to temperature as energy is added to a substance that is changing state?
The temperature remains constant during a change of state as the energy is used to break intermolecular bonds rather than increase molecular motion. Once the substance has completely changed state, the temperature will start to rise again as the added energy increases the molecular motion.

Sometimes heat energy is added but the temperature stays the same when is this?
When a substance undergoes a phase change, such as melting or boiling, heat energy is added, but the temperature remains constant. This is because the added energy is being used to break the intermolecular forces holding the substance together, rather than increasing the kinetic energy of the particles.
What happens to a substance's temperature as it god through the change of state?
During a change of state, the temperature of a substance remains constant. This is because the energy being added or removed is used to break or form intermolecular bonds rather than increase or decrease the substance's kinetic energy.

Why do substances change phases when energy is added or removed?
When energy is added to a substance, the temperature of the substance increases, causing the particles to gain kinetic energy and move faster, resulting in a phase change. Likewise, when energy is removed from a substance, the temperature decreases, causing the particles to slow down and the substance to change phases. The energy absorbed or released during these phase changes is used to either break or form bonds between the particles.
As heat is added to a substance undergoing a phase change the temperature remains constant because the energy is being used to?
break intermolecular bonds and change the phase of the substance rather than increase the kinetic energy of the particles (temperature).
As heat is added to a substance undergoing a phase change. why does the temperature remain?
Basically what it comes down to is the substance that is left behind during the phase change (say the liquid when it is changing to a vapor) has a lower internal energy than it had before the phase change started. To maintain the substance at its original temperature, an equivalent amount of energy must be added to make up for the loss of internal energy due to the phase change. (Conservation of Energy)The energy added in this case is heat, which in turn causes more molecules of the substance to change phases and lowers the internal energy & the process repeats. This is why the temperature remains constant as you add heat to a substance during a phase change. Once the phase change is completed the added heat will eventually cause the temperature to rise in the new phase of the substance. Hope this explanation helps. It's kind of hard to explain without a basic knowledge of thermodynamics.
When heat is added to or removed fron the substance and the temperature remains the the smae where is the thermal energy going?
When heat is added to or removed from a substance and the temperature remains the same, the thermal energy is being used to cause a phase change within the substance. This means that the added heat is causing the particles within the substance to change their arrangement or state of matter, rather than increasing their kinetic energy and raising the temperature.
Thermal energy added to a substance that is not changing state causes the substances temperature to do what?
The temperature of the substance will increase when thermal energy is added without changing state. This is because the thermal energy is causing the particles within the substance to move faster, resulting in an increase in temperature.

Can heat be added to a solid liquid and gas without changing in teperature?
That is possible when there is a change of state. For example, if you have ice at its melting point, or a mixture of ice and water at its melting point, if you add heat, the energy will be used to melt the ice, not to increase the temperature.
