Frosty the Snowman’s magic hat keeps him at a comfortable temperature of -11°C. However, a nearby test of a nuclear explosive device knocks off his hat and irradiates him. He absorbs 46 MJ of energy!
Part (a) Frosty’s initial mass is 104 kg of pure ice. Ignore the hat and any other ornaments. We need to determine if Frosty absorbs sufficient energy to melt completely. What is the minimum amount of energy, in megajoules, that is required to melt Frosty?
Part (b) After Frosty is completed melted at 0°C, how much energy, in megajoules, is left to do further damage? sig. gif?tid=6C65-9D-76-47-80C0-19719
Part (c) Is the energy that is left sufficient to raise the temperature of the puddle that was Frosty to the boiling point? sig. gif?tid=6C65-9D-76-47-80C0-19719
Part (d) What is Frosty’s final temperature, in degrees Celsius, after absorbing the energy from the nuclear explosion?

4. now look at the green lines you created by connecting the three boiling point data points and the three melting point data points. for each of these lines, describe any trends you see. 5. locate the elements on your periodic table that you circled in green on your graph. what term or description would you use to identify these elements with respect to the periodic table? 7. using the room temperature line (orange line) and your periodic table, make lists that identify the state of matter (gas, liquid, or solid) in which each element you plotted exists at room temperature. explain your answers.
