The element hydrogen has the highest specific heat of all elements. At a temperature of 25°C, hydrogen's specific heat is 14,253 J/kg°C. If the temperature of a 0.34 kg
sample of hydrogen is to be lowered to its freezing point which is -259° C, how
much energy will have to be lost from the hydrogen? Also write the answer in
scientific notation.

The heater element of a 120 v toaster is a 5.4 m length of nichrome wire, whose diameter is 0.48 mm. the resistivity of nichrome at the operating temperature of the toaster is 1.3 × 10-6 ω·m. the toaster is operated at a voltage of 120 v. (a) what is the power drawn by the toaster? (b) if the cost of electricity is 12 ¢ per kilowatt-hour, and it takes 2 minutes to toast bread, how much does it cost for toasted bread? (c) when the heater element is at room temperature, is the resistivity in the nichrome wire greater than, less than, or equal to it’s resistivity when at operating temperature? explain.
