You can add thermal energy to a substance without increasing its temperature by changing its phase, such as melting a solid or vaporizing a liquid. During these phase changes, energy is absorbed to break intermolecular bonds rather than increasing the substance's kinetic energy, resulting in no temperature change.

How can you add thermal energy to a substance without increasing its temparature?
One way to add thermal energy to a substance without increasing its temperature is through a phase change, such as melting or boiling. During these changes of state, the added energy is used to break the bonds between molecules rather than increasing their kinetic energy, resulting in a temporary plateau in temperature.
How can you add thermal energy to a substance without increasing the temperature?
You can increase the thermal energy of a substance by changing its phase, such as melting ice into water, or causing its molecules to vibrate more vigorously without changing the temperature, through processes like latent heat absorption or chemical reactions.
Can you add thermal energy to an object without increasing its temperature?
Yes, it is possible to add thermal energy to an object without increasing its temperature by changing its phase. For example, when ice is melting, thermal energy is being absorbed to break the bonds between water molecules without a change in temperature.
What happens to the thermal energy of a substance during a change of state?
During a change of state, the thermal energy of a substance is used to break or form intermolecular bonds rather than raise the temperature. This leads to a phase transition, such as melting or boiling, where the substance either absorbs or releases energy without increasing its temperature.
How can you have temperature without heat?
Temperature is a measure of the average kinetic energy of the particles in a substance, while heat is the transfer of energy between substances due to a temperature difference. It is possible to have a substance at a certain temperature without any transfer of heat occurring, for example, when the substance is thermally isolated or in thermal equilibrium.

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.
What happens to the thermal energy of a substance during a physical change of state?
During a physical change of state, such as melting or boiling, the thermal energy is used to break the intermolecular forces holding the substance together rather than increasing the temperature. Once these forces are overcome, the substance changes its state without a change in temperature.
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

It is possible to have a substance at a certain temperature without any transfer of heat occurring, for example, when the substance is thermally isolated or in thermal equilibrium.
What volume will it occupy at 45 c?
To determine the volume of a substance at a specific temperature, you would need to know the substance's initial volume, its coefficient of thermal expansion, and the change in temperature. Without this information, it is not possible to provide an accurate answer.
Think critically how can the temperature of a substance remain the same even if the substance is absorbing thermal energy?
The substance could be undergoing a phase change, such as melting or boiling, where the absorbed thermal energy is being used to break intermolecular forces rather than increase temperature. Additionally, the substance could be acting as a reservoir for the thermal energy, buffering the temperature change by absorbing it without changing its own temperature until it reaches its heat capacity limit. Finally, the substance could be releasing an equivalent amount of energy through other means, such as radiation or convection, balancing out the absorbed thermal energy and maintaining a constant temperature.
How can you add thermal energy to a substance without increasing its temprrature?
That happens when there is a phase transition; for example, when ice melts, it takes energy to convert ice at zero degrees, to water at zero degrees.
Can heat be added to a substance without causing temperature of the substance to rise?
Yes, it is possible to add heat to a substance without causing a rise in temperature if the substance undergoes a phase change, such as melting or boiling. During these phase changes, energy is absorbed to change the state of the substance rather than increasing its temperature.
