Hi, I'm trying to work this problem out and unfortunately my book doesn't have an explanation.(adsbygoogle = window.adsbygoogle || []).push({});

1. The problem statement, all variables and given/known data

A match head is rubbed a distance d over a rough surface in order to increase the temperature to its flash point. If the patch head material has a mass m and a specific heat c, which equation represents the average force needed to raise the match head's temperature by [tex]\Delta[/tex]T?

2. Relevant equations

The answer is:

[tex]F=\frac{mc\Delta T}{d}[/tex]

3. The attempt at a solution

Do I simply set specific heat capacity (Q) to W: [tex]Q=W[/tex] and get:

[tex]mc\Delta T=Fd[/tex]

and move d over?

I'm working in a MCAT study book and it doesn't go into detail about the heat capacity equation that it gives me, but I'm trying to understand this a little more fully. Thanks for any help!
