Final answer:
To find the change in temperature (T), the heat flow (Q) is divided by the product of mass (M) and specific heat (C), resulting in the equation T = Q / (MC).
Step-by-step explanation:
The formula Q = MCT represents the relationship between heat flow (Q), mass (M), specific heat (C), and change in temperature (T). To solve this formula for the change in temperature (T), we need to isolate T by dividing both sides of the equation by the product of mass (M) and specific heat (C). The correct rearrangement of the equation is T = Q / (MC), which represents how much temperature will change for a given amount of heat flow.
