One way to add heat to a substance without raising its temperature is by changing its state of matter. This process, known as phase change, involves adding heat energy to a substance to change it from a solid to a liquid or from a liquid to a gas. During this phase change, the temperature of the substance remains constant until the phase change is complete.
What else can I help you with?
How can temperature be increased without heating?
It is possible to add heat to a substance without changing its temperature. That happens during melting and boiling. However, I cannot think of a case in which the temperature of a substance increases without heat being added to it, either by radiation, conduction or convection.
Will taking heat out of air raise or lower the temperature?
Heat is what causestemperatureto be raised, so if you take heat out, it would lowerthetemperature.
What is the difference in specefic heat and latent heat?
Specific heat is the heat energy in joules required to rise the temperature of one kg of substance through one kelvin without a change in its state. But latent heat is the heat required to change the state of one kg of substance without change in 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.
Which heat changes the state of a substance without changing its temperature?
Latent heat is the heat that causes a change in the state of a substance without changing its temperature. This process involves absorbing or releasing energy to break or form intermolecular forces between particles.
Can you ever heat a substance without raising its temperature?
no
Under what conditions heat can be given to a substance without raising its temperature?
If the substance is in solid condition and at the melting temperature, heat can be given without rising the temperature. Then the substance melts and all the heat will be used in the melting process. Also when the substance is at the boiling temperature you can add heat without rising the temperature. At that point the heat is used to vaporate the substance.
How can a matter change from solid state to liquid state and reverse the process?
At a unique temperature, called the "freezing point", for each pure substance at a constant pressure, a solid form of the substance can change from solid to liquid phase by absorbing heat energy from its environment without raising the temperature of the substance, and, at the same temperature and pressure, a liquid phase of the same substance, can solidify without changing its temperature if it can transfer heat energy to the external environment.

How are sensible heat and latent heat different in terms of their impact on temperature changes in a substance?
Sensible heat and latent heat are different in how they affect temperature changes in a substance. Sensible heat directly raises or lowers the temperature of a substance when added or removed, while latent heat causes a substance to change its state (such as melting or evaporating) without changing its temperature.

Sensible heat involves a change in a substance's?
Sensible heat involves a change in a substance's temperature without a change in its phase. It is the heat exchange that causes a change in the temperature of a substance but does not result in a change of state (solid, liquid, gas).
Which heat changes the state of a substance without changing its temperature?
Latent heat is the heat that causes a change in the state of a substance without changing its temperature. This process involves absorbing or releasing energy to break or form intermolecular forces between particles.
What property of a substance does its specific heat capacity describe?
How much heat it takes to raise the temperature
The amount of energy involved in melting a substance without changing its temperature is called the?
It is called the enthalpy of fusion of a substance, also known as (latent) heat of fusion.
