Answer:
a) The heat which we supply to water during boiling is used to overcome these forces of attraction between the particles so that they become totally free and change into a gas. This latent heat does not increase the kinetic energy of water particles and hence no rise in temperature takes place during the boiling of water.
b) Steam produces more severe burns than boiling water even though both are at 100oC because steam contains more heat, in the form of latent heat, than boiling water.

Answer:
0.396 J/g°C (to 3 sf)
Explanation:
50.0 = 10.6(24.9-13.0)(c)
c = 0.396 J/g°C (to 3 sf)
Hello!
<span>In the celebrated equation e = mc2, the c2 is the </span>proportionality constant of energy and mass.
This famous equation was proposed by Albert Einstein in 1905, and implies that when there is a certain mass, there is a certain amount of Energy associated with it even is the mass is in a steady state. The proportionality constant c² is the speed of light squared.
Have a nice day!
