What else can I help you with?
Does sublimation get more energy or less?
more. in any case, going from a solid to a gas requires more energy than going from a solid to a liquid. Considering Hess's Law, break down the reaction into two parts; solid to liquid, and then liquid to gas. Total energy of sublimation of the substance will be the sum of the two reactions.
Does melting require the absorption of energy?
Yes, melting requires the absorption of energy in order to overcome the forces holding the particles together in a solid phase. This added energy allows the particles to move more freely and transition into a liquid state.
Why does a bus going uphill travel more-slowly than going?
A bus going uphill must overcome the force of gravity pulling it back down, which requires more energy and makes it move more slowly. Going downhill, the bus benefits from gravity assisting its motion, allowing it to travel faster.
Green light emitted by excited mercury vapor corresponds to a particular energy transition in the mercury atom a more energetic transition might emit?
A more energetic transition in the mercury atom might emit blue light, as it corresponds to a higher energy level jump compared to the green light transition. This transition involves the emission of photons with higher energy values than those emitted during the green light transition.
Which requires more power-walking or running up the steps and why?
Running up requires more power. The reason is that you spend the same energy in less time.Running up requires more power.

Does melting require an input of energy?
Yes, melting typically requires an input of energy in order to overcome the forces holding the solid together. This energy breaks the bonds between the particles in the solid, allowing them to move more freely and transition into a liquid state.

Yes, melting requires the absorption of energy in order to overcome the forces holding the particles together in a solid phase. This added energy allows the particles to move more freely and transition into a liquid state.

Does turning a fluorescent bulb on and off use more energy than leaving it on for a few hours?
i believe so because turning the light bulb on requires a stronger "burst" of energy to get it going, whereas maintaining it you're not pulling more energy in shorter bursts.

What requires the movement of particles from a less crowded area to a more crowded area?
It requires energy.
Why does pulling a load up requires more effort?
it requires more energy to pull because the load is heavier than the effort.
Why do you take in more air when running?
Running equals increased energy production, which requires more oxygen, which requires more air per minute.
What requires more energy melting or boiling?
Melting requires energy input or absorption because liquid water has more energy than solid water.
Do transition have higher melting point than alkaline and alkali metals?
Yes, transition metals generally have higher melting points compared to alkaline and alkali metals. This is because transition metals have a greater number of valence electrons and a stronger metallic bond, which requires more energy to break and transition from solid to liquid. In contrast, alkaline and alkali metals have fewer valence electrons and weaker metallic bonds, resulting in lower melting points.
