Question

1 kg of ice at zero degree celsius is be continuously heated through an electric heater of 1 kilowatt assuming that all the heat is transmitted to ice calculate the time interval is second for converting ice to water at hundred degree celsius specific latent heat of fusion of ice is equal to 336 joule per gram specific heat of capacity of water is equal to 4.2 joule per gram degree celsius​

Answer 1

calculate the volume of O2 required for combustion of 11.2 litre butane the percentage purity of o2 is 60 percentage?

Charge on 1 electron= 1.6x10^-19 C

So, in 1 coulomb of charge 1/(1.6x10^-19)

= 6.25x10^18 ...
