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.
