(1) Consider a glass full of ice at the melting point. Pressure =1atm.5+2+5+6=18 points (a) Draw the temperature (y-axis) and heat (x-axis) diagram until all water completely vaporizes. (b) Indicate the phase transformation zone (ice to water, water to vapor). (c) Is there any change in temperature during latent heat? Explain the fundamental reason in few lines. (d) Indicate how kinetic and potential energy changes. Explain the fundamental reason in few lines
