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?

Which of the following is a false statement about dispersion forces? view available hint(s) which of the following is a false statement about dispersion forces? dispersion forces are the result of fluctuations in the electron distribution within molecules or atoms. dispersion forces are present in all atoms and molecules. dispersion forces result from the formation of instantaneous dipoles in a molecule or atom. dispersion forces always have a greater magnitude in molecules with a greater molar mass. dispersion force magnitude depends on the amount of surface area available for interactions.
