WebIt’s an algebra problem where we’re solving for ΔT in the heat capacity equation. So, q = mCΔT, given equation q/(mC) = ΔT, divide by m and C for both sides of the equation. … WebYou can actually use any measure of temperature with newtons law of cooling because it deals with temperature generally (no units). Its the same for the time variable. In his example, Sal uses an arbitrary 2 to represent 2 mins. That could actually represent 2 days, weeks, hours, or years. Essentially, then, what you get out of the equation for ...
