Which changes of state should she place in the column titled lose energy?
The changes of state that involve losing energy are condensation (gas to liquid), freezing (liquid to solid), and deposition (gas to solid). These changes require the release of energy, typically in the form of heat, to facilitate the transition.
What is the difference between sensible heat gain and latent heat gain?
When an object is hot, the temperature rises as heat is added. This increase in heat is called sensible heat. Solids can become liquids and liquids can become gases but changes like this require the addition or removal of heat. The heat that causes these changes is called latent heat.
What are two changes of state for water that cause latent heat to be released?
When water vapor condenses into liquid water, latent heat is released. Similarly, when liquid water freezes into ice, latent heat is also released. These changes of state involve the release of latent heat because energy is being released as the water molecules transition to a lower energy state.
What is unsteady state of heat transfer?
Unsteady state heat transfer occurs when the temperature of an object changes with time, indicating that the system is not in thermal equilibrium. This can happen during the initial warm-up or cool-down of a system, or when there are sudden changes in external conditions affecting heat transfer. The rate of heat transfer during unsteady state conditions is not constant and varies with time.
What is a change of state in which energy is added as it changes state?
Solid --> Liquid. Liquid -> Gas. Solid --> Gas.
What all changes of the state of matter require?
heat energy
What two processes need heat to happen?
Melting, where a solid changes to a liquid state, and vaporization, where a liquid changes to a gas state, are two processes that require heat to happen. These phase changes involve absorbing thermal energy to break intermolecular forces holding the particles together.

When does matter change state?
when water gains or loses heat, it changes its state. When liquid water gains heat, it changes its state from liquid to gas. It becomes water vapor. When solid gains heat, it melts an changes its state from solid to liquid. When gas loses heat, it condenses into liquid. Gas, to liquid. When liquid loses heat, it becomes solid
Heat causes physical changes in matter by changing?
Typically heat changes the STATE of matter from solid to liquid to gas.However, heat can also cause chemical changes for example combustion.
What three phase changes require the addition of heat?
I think melting, condensation and Sublimination.
How do you convert heat energy to light energy?
solar energy. heat from the sun gives you heat and changes to light because heat can be used for light.
What changes the state between a solid and a liquid?
more energy, for the most part heat, changes the state between solid and liquid.
How does electricity causes changes in matter?
when electricity is passed, it also generates heat energy. And this heat energy, produced by electricity, changes the state.

What is the study of heat transfer during chemical reactions and changes of state is?
The study of heat transfer during chemical reactions and changes of state is known as thermochemistry. Thermochemistry deals with the heat of reaction, enthalpy, and heat transfer in chemical processes. It is important in understanding the energy changes associated with chemical reactions.
Which state changes are exothermic and endothermic?
freezing is exothermic, melting is endothermic, evaporation is endothermic, condensation is exothermic.
