What else can I help you with?
What reaction involves a net absorption of energy?
a reactions that has a net absorption is a endothermic reaction
What are changes of state that require energy?
Melting, vaporization, and sublimation are changes of state that require energy. During these processes, energy is used to overcome intermolecular forces holding the particles together so that they can move more freely.
What does light absorption require the presence of?
Light absorption requires the presence of a material that is capable of absorbing light energy. This material typically contains atoms or molecules that can undergo a transition of electron energy levels when exposed to light, resulting in the absorption of photons.
What changes of state require energy?
Sublimation, melting, and vaporization are three changes of state which require energy.
Identify to changes of state that require energy to be used and two changes of state that require the release of energy?
Changes of state that require energy: melting (solid to liquid) and vaporization (liquid to gas). Changes of state that release energy: freezing (liquid to solid) and condensation (gas to liquid).
What is the melting of sodium is accompanied by?
absorption of energy
Melting snow produces what kind of energy?
Thermal energy absorption
What requires more energy melting or boiling?
Melting requires energy input or absorption because liquid water has more energy than solid water.
The absorption of what monosaccharide does not require energy?
The absorption of glucose does not require energy. Glucose absorption occurs through facilitated diffusion, where glucose molecules move across the intestinal membrane down their concentration gradient with the help of transport proteins, such as GLUT2.
Is melting pysical or chemical?
Melting is a physical process, not a chemical one. It involves a change in state from a solid to a liquid due to the absorption of heat energy.

Melting, vaporization, and sublimation are changes of state that require energy. During these processes, energy is used to overcome intermolecular forces holding the particles together so that they can move more freely.
What kind of heat is the energy used to evaporate water or melt snow?
Evaporation is due to the kinetic energy of molecules; melting is due to the absorption of thermal energy.
What does light absorption require the presence of?
Light absorption requires the presence of a material that is capable of absorbing light energy. This material typically contains atoms or molecules that can undergo a transition of electron energy levels when exposed to light, resulting in the absorption of photons.
Why sodium has a high melting temperature?
Sodium has a high melting temperature because it has strong metallic bonds between its atoms. These bonds require a significant amount of energy to break, resulting in a high melting point for sodium.
