6.105 A piece of lead of mass 121.6 g was heated by an elec- trical coil. From the resistance of the coil, the current, and the time the current flowed, it was calculated that 235 J of heat was added to the lead. The temperature of the lead rose from 20.4°C to 35.5°C. What is the specific heat of the lead?

Transcribed Image Text:### Problem 6.105
A piece of lead with a mass of 121.6 grams was heated using an electrical coil. By measuring the resistance of the coil, the current, and the duration for which the current was applied, it was determined that 235 joules of heat were transferred to the lead. As a result, the temperature of the lead increased from 20.4°C to 35.5°C. The task is to calculate the specific heat capacity of the lead.
