If the specific latent heat of ice is 340 000 J/kg, and the specific latent heat of steam is
2 300 000 J/kg and the specific heat capacity
of water is 4200 J/kg K, calculate the heat
needed to change 2 kg of ice at 0°C to steam
at 100 °C.

6 d

explanation:

the answer would most likely be c, because if it's a comical piece of information, it may likely not be true, if it's a site that allows anybody to edit the content, it could mean a five year old is typing the info, and if it's a tv show produced by a celeb, it may have a biased opinion.

305.7

explanation:

density =m/v

density =917/3.00

density = 305.

approximately = 305.7

in four significant figures

electric field is a function of 1/r^2

yes, the force per unit charge for a point charge is inverse square law.
