examples of substance that condences,and examples of substance that also fuses(fusion)?

Question

fusion,.,example from solid to liquid.,.

Answer 1

water vapor (steam) will condense to liquid water and solid water (ice) will melt to liquid water.

Answer 2

Most tings taht are a gas, at the right temperature will condense or turn to a liquid. We have liquid air from which we obtain many of the rarer gases.
Most things , at the right temperature will change from a liquid to a solid or fuse. If we reduce the temperature we can solidify many things that are liquids at room temperature, or even things that are gases at room temp.
Water is an example that has all 3 stages fairly close together. Freeze at ) C and boil at 100C. That means that it will also condense at 100 C and fuse at ) C.
Mercury will solidify at -40F or C. That is the point tht C and F are the same.

Answer 3

Almost all substances have this property.

eg. Water as mentioned above.
Iron on application of heat turns first to liquid and then to gas.
CO2 on drainage of heat first turns to liquid CO2 and the to solid CO2 or dry ice.

Answer 4

Steam at 100°C will condense to water at 100°C by the REMOVAL of 'Latent Heat of Condensation' (No change in temperature), which is: ...
540 calories/gram or 2260 Joules/gram. (Also 970 Btu/lb)

Ice at 0°C will fuse (melt) to water at °C by the ADDITION of 'Latent Heat of Fusion' (No change in temperature), which is:...
80 calories/gram or 334 Joules/gram. (Also 144 Btu/lb)
