Question

When you hammer a nail into wood, the nail heats up. 30 Joules of energy was absorbed by a 5-g nail as it was hammered into place. How much does the nail's temperature increase (in °C) during this process? (The specific heat capacity of the nail is 450 J/kg-°C, and round to 3 significant digits.

Answer 1

13.33 K

Step-by-step explanation:

Given that,

Heat absorbed, Q = 30 J

Mass of nail, m = 5 g = 0.005 kg

The specific heat capacity of the nail is 450 J/kg-°C.

We need to find the increase in the temperature during the process. The heat absorbed in a process is as follows:

`Q=mc\Delta T\\\\\Delta T=(Q)/(mc)\\\\\Delta T=(30)/(0.005* 450)\\\\=13.33\ K`

So, the increase in temperature is 13.33 K.
