first substance‚ is equal to the heat gained by the second substance‚ and therefore: Qsubstance 1 = -Qsubstance 2 [2] Since the law of conservation of energy states that energy cannot be created or destroyed‚ the change in energy must equal zero and therefore the left side of this equation must be equal in magnitude but opposite in sign of the right side. By substituting equation [1] into equation [2] we are able to derive: m1 · c1 · Δt1 = - (m2 · c2 · Δt2) [3] and thus we are able

Effects of Temperature on Enzyme Biology Introduction In order to understand the activity of enzymes at different temperatures the ability of the enzyme to function can be measured. This is important in many applications such as Polymerase Chain Reaction for forensics as well as genetics research where manipulation of temperature-dependent enzymes allows for replication of DNA segments. Bennett states‚ “when the energy - measured
