What else can I help you with?
Is evaporation energy loss or gain?
Evaporation is considered an energy gain process because it requires energy input to break the bonds between liquid molecules to change them into vapor. This energy input comes from the surrounding environment, which leads to cooling of the remaining liquid.
When the hydrosphere receives energy from the Sun what does water do A.condenses. B.precipitates. C.evaporates. D. runs off?
The only process which requires the input of energy is evaporation.
Why is it thermodynamically possible for some ionic solids to dissolve even though the solution process is endothermic?
Even though dissolving some ionic solids is an endothermic process (requires energy input), it is still thermodynamically possible due to the increase in entropy that occurs when the solid breaks apart into individual ions in solution. The increase in entropy favors the dissolution process, even if it requires energy input to overcome the lattice energy holding the solid together.
Does vaporizing require an input or energy?
Yes, vaporizing requires an input of energy to heat the substance to its vaporization point. This energy causes the substance to change from a solid or liquid state to a vapor or gas state.
Why does a heat pump need an external source or energy?
A heat pump requires an external source of energy to transfer heat from a low-temperature area to a high-temperature area. This process of moving heat against the natural flow requires energy input, typically in the form of electricity, to power the compressor and circulate the refrigerant.
Which process in the water cycle requires the direct input of energy?
Evaporation.
Does the process of bond breaking release energy?
Yes, the process of bond breaking requires energy input, not release.
Is chocolate melting absorbing or releasing energy?
Melting chocolate requires energy input because the solid chocolate is transitioning into a liquid state. The energy input breaks the molecular bonds holding the solid together, absorbing energy in the process.
Is the process of breaking bonds endothermic or exothermic?
The process of breaking bonds is endothermic, meaning it requires energy input to break the bonds.
What process requires an input of energy?
Any form of active transport, which can be defined as any movement of molecules against or independent of a concentration gradient. Examples include pumps and endocytosis
What is the sign of delta g for a spontaneous process?
The sign of ΔG (Gibbs free energy change) for a spontaneous process is negative. This indicates that the process can occur without external input of energy, as it results in a decrease in free energy. In contrast, a positive ΔG signifies a non-spontaneous process that requires energy input to proceed.
What input is necessary for the breaking of covalent bonds, which requires the input of energy?
The breaking of covalent bonds requires the input of energy. This energy can come from various sources such as heat, light, or electricity.
Witch process requires no energy from the cell?
Passive transport processes, such as simple diffusion and facilitated diffusion, do not require energy input from the cell. These processes rely on the movement of molecules along a concentration gradient, from an area of high concentration to low concentration.
Is photosynthesis a spontaneous process?
Photosynthesis is not a spontaneous process because it requires energy input from sunlight to convert carbon dioxide and water into glucose and oxygen.
Energy release is to condensation as energy input is to?
Energy release is to condensation as energy input is to vaporization. Vaporization requires energy input to happen, while condensation releases energy.
Is active transport an endergonic or exergonic process?
Active transport is an endergonic process, meaning it requires energy input to move molecules against their concentration gradient.
What requires more energy melting or boiling?
Melting requires energy input or absorption because liquid water has more energy than solid water.
