What else can I help you with?
Is endothermic melting or freezing?
Melting is endothermic. Freezing is exothermic.
Is melting ice cubes endo or exothermic?
No, freezing is exothermic as the water loses energy to its surroundings as it freezes.
Which of these processes have the same magnitude of energy change but are opposite in sign?
Endothermic and exothermic reactions have the same magnitude of energy change but are opposite in sign. In an endothermic reaction, energy is absorbed from the surroundings, while in an exothermic reaction, energy is released to the surroundings.
What do you need to melt a solid in energy flow terms?
Melting is an exothermic process; we need heat for melting.
Is melting scoop of ice cream an example of an exothermic process?
No, melting an ice cream scoop is an endothermic process because energy is absorbed to break the intermolecular bonds and change the solid ice cream into its liquid form.
The melting of ice cubes is a exothermic reaction?
No, it is a physical change, not a chemical reaction.
Is freezing an example of an exothermic chemical change?
No because in an exothermic change energy is released not taken in. Melting would be an example of exothermic change.
Which of the following examples involves an exothermic change?
Examples for exothermic change are burning of fuels or coal, burning of a fire cracker and glowing of an electric lamp.
Is endothermic melting or freezing?
Melting is endothermic. Freezing is exothermic.
Is melting ice cubes endo or exothermic?
No, freezing is exothermic as the water loses energy to its surroundings as it freezes.
Is a melting candy bar exothermic?
yes
Is melting process a endothermic and exothermic?
endothermic
Is freezing an endothermic change or a exothermic change?
It is an exothermic change
Is melting of candle an exothermic or endothermic reaction?
The melting of a candle is an endothermic process because heat is required to break the intermolecular forces holding the solid wax together and convert it into a liquid. Energy is absorbed during this phase change.
Is melting an exothermic or an endothermic process?
It is an endothermic process.
Which state changes are exothermic and endothermic?
freezing is exothermic, melting is endothermic, evaporation is endothermic, condensation is exothermic.
Which of these processes have the same magnitude of energy change but are opposite in sign?
Endothermic and exothermic reactions have the same magnitude of energy change but are opposite in sign. In an endothermic reaction, energy is absorbed from the surroundings, while in an exothermic reaction, energy is released to the surroundings.
