This is from a calorimetry lab. $50\ \mathrm{ml}$ of acid and base were mixed. Why does the temperature keep decreasing after 1 minute and why isn't at a constant rate?

Is it because heat is lost to the surroundings?

  • $\begingroup$ The link is not visible to the general public. This is unlikely due to heat loss, as that wouldn't be linear. Especially not if it wasn't well-mixed, which it probably isn't. More information is going to be needed. $\endgroup$ – user7652 Nov 19 '15 at 11:09
