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 47 MJ of energy! Frosty’s initial mass is 99 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?
Frosty the Snowman’s magic hat keeps him at a comfortable temperature of -8°C. However, a nearby test of a nuclear explosive device knocks off his hat and irradiates him. He absorbs 47 MJ of energy! Frosty’s initial mass is 103 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? After Frosty is completed melted at 0°C, how much energy, in megajoules, is left to do further damage?
Suppose you require 2500 food Calories per day. a. What is your average power, in watts? b. How much energy, in joules, do you require from food in a year? Counting all forms of energy (such as gasoline, electricity, and energy for heating), the average person consumes about 350 billion joules of energy each year. Compare this value to the energy needed from food alone. a. What is your average power, in watts? Approximately 121 watts (Round to the nearest whole number as needed.) b. The energy required from food is approximately billion joules per year. (Round to the nearest tenth as needed.)
