It means that 22.5×10^5 J of heat is required to change 1 kg of water into steam.
Latent heat of vaporization is amount of energy required to change 1 gram (in this example 1 kilogram) of material from the liquid to the gaseous state at its boiling point.
Boiling point of the water is 100°C.
Joule (J) is the standard unit for energy (in this example heat).
Evaporization is phase change process in which the water changes from a liquid to a gas (water vapor). Fore example, solar radiation can be the source of energy for evaporation.

70%
air water and food
carbon dioxide
oxygen
a green pigment
heterotroph
Explanation:
sorry if its wrong i used my best of knowledge i didnt rlly understand most of it
The volume of Iron (in cm^3) = 4840/7.86 = 615.78 cm^3.
1 cm^3 = 1 mL and there are 1000 mL in 1 dL
So to convert from cm^3 to dL, we just have to divide by a 1000
615.78/1000 = 0.61578 dL
Answer:
<u>NONE OF THE ABOVE </u>
Explanation:
None of the above are examples of an oxidation - reduction or a redox reaction . This is because there is no change in the oxidation state of any of the elements in the reaction when the reaction happens .
- <em> For a redox reaction , transfer of electrons must take place.</em>
- <em>The oxidation states must increase or decrease in atleast 2 of the elements of a compound.</em>
- For example :
⇒
