# What if I am not given the initial or final temperature, only the change in temperature? Can I still calculate for the heat flow?

No, it doesn't matter, as long as you know what the final temperature is. Remember, it's the change in temperature that correlates with the heat required to flow through the system. As long as you know ${T}_{f}$ and ${T}_{i}$, you'll know what $q$ is.
Not even your average $\Delta T$ or standard deviation of $\Delta T$ should change.
