can some clearly explain the thermal energy equation? q=m(tf - ti)ci know that  q is change in thermal energy which is measured in joules m is mass the ts mean change in temperature and c is specific heat. what i want to know is how to do the equation. my book doesn't explain it well. take your time to explain clearly my brain is dead you can use illustrations or whatever but do so clearly.

So what the thermal energy equation tells you is the internal heat energy a system gives you due to the movement of particles/temperature. This heat is due to the kinetic energy in the particles. Q represents the heat transfer of a material that has a specific mass, m, specific heat, c, and some temperature or change in temperature, ΔT. For example, say you have an object of mass 1kg, specific heat 0.5J/kg°C and the temperature changes from 50°C to 100°C. To find the heat transfer you would use the equation Q= 1kg*0.5J/kg°C*(100°C-50°C). This would tell you that the heat transfer of this particle is 25J which means that 25J of energy are transferred from one point to the other in this system.
