Steam machines are used to sterilise kitchen work surfaces. Calculate the energy needed to change 60 g of water into steam.
The latent heat of vaporisation for water is 2.26106 J/kg.
Use the correct equation from the Physics Equations Sheet.

Which energy transformation occurs in the core of a nuclear reactor? nuclear energy mechanical energy nuclear energy - thermal energy thermal energy -- nuclear energy mechanical energy - nuclear energy

Sort the images based on whether there's a force of attraction or repulsion between the magnets shown. attraction repulsion

Calculate the minimum energy required to remove one proton from the nucleus 126c. this is called the proton-removal energy. (hint: find the difference between the mass of a 126c nucleus and the mass of a proton plus the mass of the nucleus formed when a proton is removed from 126c.) express your answer with the appropriate units. emin e m i n = nothing nothing request answer part b how does the proton-removal energy for 126c compare to the binding energy per nucleon for 126c, calculated using eb=(zmh+nmn−azm)c2?
