When something goes from it's liquid form to solid, it is a heat loss. A simple example is making an ice-pop in a freezer. The liquid fruit-juice/water mixture has to lose heat to the freezer (and the other contents) in order to solidify. Subsequently it has to gain heat from your mouth to melt when you eat it (which is why it feels cold).
What else can I help you with?
Is evaporation heat gain or heat loss?
For what?It requires a heat gain for the water,but a heat loss for whatever the water is in contact with.
Why is a thermos flask good at keeping drinks cold as well as hot?
Because it has good insulation so it prevents boss loss and gain of heat from the surrounding ---- Well that's true, but more interestingly, it has a glass chamber inside which is smaller than the outer casing. The air between the glass chamber and the outer casing has had almost all of the air removed, and is therefore a vacuum. This makes the heat unable to escape between the inner chamber and the outer casing, keeping the liquid hot. It also stops heat from outside being able to get into the liquid stored in the glass chamber, therefore keeping it cold. Most of the heat from the flask is lost from the lid, since the liquid has to come out of somewhere.
What do all changes of state in matter require?
heat energy
Will the water temp drop in a closed loop system or will it maintain 50 degrees?
In a closed loop system, the water temperature will generally maintain a stable temperature, such as 50 degrees, as long as there is no heat loss or gain from external sources. However, if there are inefficiencies in the system, such as heat loss through insulation or heat exchange with the environment, the temperature may drop over time. Additionally, if the system is actively using heat (e.g., for heating purposes), the temperature will decrease unless it is replenished with heat.
Describe a method of insulation that can completely eliminate heat loss by conduction?
Installing fiberglass batting will completely eliminate heat loss.
Is melting heat gain or heat loss?
Melting is a process that requires heat to change a solid substance into a liquid, so it is a heat gain process. Heat is absorbed to break the bonds between the molecules in the solid and allow them to move more freely as a liquid.
By removing heat what happesn 1. a liquid changes to a solid. 2 a solid changes to a liquid. 3 a liquid changes to a gas. 4. a solid changes to gas?
A liquid changes to a solid when heat is removed, as the molecules lose energy and come together in a more ordered structure. A solid changes to a liquid when heat is applied, causing the molecules to gain energy and break free from their fixed positions. A liquid changes to a gas when heat is added, increasing the molecular motion and allowing them to escape into the vapor phase. A solid changing directly to a gas is called sublimation and occurs when the substance bypasses the liquid phase by gaining enough energy to transition from solid to gas.
Is precipitation heat loss or heat gain?
heat loss
How does evaporation change from a liquid to a solid?
Evaporation is the process where a liquid turns into a gas, not a solid. The change from a liquid to a solid is called solidification or freezing, where the particles of a liquid come together to form a solid structure as the temperature decreases.
Is freezing ice heat gain or heat loss?
Freezing ice is a process that involves heat loss. When liquid water turns into ice, heat escapes from the water, causing it to lose energy and lower in temperature.
Requires a gain or loss of heat energy?
A temperature change requires as gain or loss of heat energy.
What is the temperature at which a liquid changes to a solid called is there a gain or a loss of energy?
Such a temperature is known as Freezing point of the liquid, during the freezing process the system losses the energy.
What is required for a phase change to occur?
Change of the phase of electrical current in a circuit or of an el magnetic wave propagating in space means change of the rate of oscillations per second of the source (generator, in particular) of the oscillations. In FM (frequency modulated )radio wave transmission sounds (music, speach) are made to modulate frequency of the generator - its rate of oscillations is changing according to the changes in phase of the vibrations of sound waves in air.
Is condensation a energy loss or gain?
Condensation is typically considered an energy loss because it releases energy as heat when water vapor changes to liquid water. This energy is known as latent heat of condensation.
Is evaporation heat gain or heat loss?
For what?It requires a heat gain for the water,but a heat loss for whatever the water is in contact with.
What is adiabatic combustion?
NO Heat Loss , No Heat gain
What makes a liquid a solid?
a loss in energy cause the change from liquid to solid like-wise a rise in energy causes a change from solid to liquid.
