Heat is often required to separate compounds because it provides the energy needed to overcome the intermolecular forces or chemical bonds holding the molecules together. For example, in processes like decomposition or phase changes, increasing temperature can supply the necessary kinetic energy to break these bonds. Additionally, heat can facilitate reactions that lead to the formation of simpler substances, enabling the separation of compounds.

To determine the heat lost, we need to calculate the heat required to cool the steam from 400 K to 273 K (its condensation point), then the heat required to change it from steam to liquid water, and finally the heat required to freeze the water into ice at 273 K. These steps involve the specific heat capacities of water and steam, latent heat of vaporization, and latent heat of fusion.
To calculate the heat required to reduce the temperature of steam from 212°F (100°C) to a lower temperature, you need to know the final temperature. The heat required can be calculated using the formula ( Q = mc\Delta T ), where ( m ) is the mass of the steam, ( c ) is the specific heat capacity of steam (approximately 2.01 J/g°C), and ( \Delta T ) is the change in temperature. If you provide the final temperature, I can give you the specific amount of heat required.
No heat (energy) is required to freeze water (from liquid to solid). Freezing RELEASES energy (heat), as it is an exothermic event. If you want to know how much energy is release, you need to know the heat of fusion for water, and then multiply that by the mass of water being frozen.
No, a compound doesn't need to be colored to be separated by chromatography. There are plenty of detectors that can be used outside of the visible spectrum, and in fact don't even use spectroscopic methods, such as Electron Capture detection (ECD).

I do not know of any jurisdiction in which a license would be required for a heat pump.
Yes, a furnace is not required when installing a heat pump as the heat pump can provide both heating and cooling functions.
A compound can be separated from a mixture without being chemically altered; the separation of elements from a compound need chemical reactions.
They are separate nations, so a visa is required.
You cannot accurately determine what size furnace is required based on the total square feet of a given space or structure. To accurately determine how much heat is required to heat your, you would need to have a Manual J Heat Load Calculation performed.
To separate sunflower seeds from sand you will need a fine filter, such as a screen. A screen that may work for you are the screens use in the common window.

We need compounds for our body to process properly. That is exactly why we need compounds. I hope this answer helps you. :)

If you want to separate ferrous oxalate from titanium oxalate, you need to put them in an alkaline solution and introduce heat. They should break apart into their two respective oxolates.
