Solid to gas (sublimation) is endothermic (takes in heat).
In other words:
A phase change from the solid state to the gas state is endothermic.
Sublimation is endothermic (takes in energy).
Heat energy must be provided to make it work.
When there is a change of state from a solid to a liquid, a solid to a gas, or a liquid to a gas, at a constant temperature, the process is endothermic NOT exothermic. It requires energy to break the intermolecular forces that keep the molecules together, and that reduces the temperature - heat is taken in.
What else can I help you with?
Is wax in a candle burning an exothermic process or endothermic?
Burning a candle is an exothermic process because it releases heat energy. The chemical reaction between the wax and oxygen produces both light and heat, making it exothermic.
Is freeezing endothermic or exothermic?
Freezing is exothermic, as the substance that is freezing loses energy to its surroundings.
Is the process feeling cold exothermic or endothermic?
Exothermic/endothermic is a process not a feeling.
What is process that involves absorption of heat?
endothermic reaction a positive enthalpy.
When you burn a log in the fireplace or burn gasoline in a car is the reaction an endothermic or exothermic reaction?
Both burning a log in a fireplace and burning gasoline in a car are examples of exothermic reactions. These reactions release energy in the form of heat and light as they occur. The heat and light produced during the combustion process are key to generating the energy needed to heat a room or propel a vehicle.
Is burning alcohol an exothermic or endothermic process?
Exothermic
Is burning petrol exothermic or endothermic?
Burning petrol is an exothermic process. It releases heat and light as energy is given off during the combustion of petrol.
Is wax in a candle burning an exothermic process or endothermic?
Burning a candle is an exothermic process because it releases heat energy. The chemical reaction between the wax and oxygen produces both light and heat, making it exothermic.
Is freeezing endothermic or exothermic?
Freezing is exothermic, as the substance that is freezing loses energy to its surroundings.
Is burning leaves a endothermic or exothermic process?
Burning leaves is an exothermic process because it releases heat and light energy as a result of the chemical reactions that take place during combustion.
Is the process feeling cold exothermic or endothermic?
Exothermic/endothermic is a process not a feeling.
Classify the burning of natural gasses in exothermic or endothermic changes?
The burning of natural gas is an exothermic process.
Is melting an exothermic or an endothermic process?
It is an endothermic process.
Is melting process a endothermic and exothermic?
endothermic
Is dissociation an endothermic or exothermic process?
Dissociation is an endothermic process.
Is fission an endothermic or exothermic process?
Fission is an exothermic process.
What is process that involves absorption of heat?
endothermic reaction a positive enthalpy.
