Identify the formula for calculating the heat flow, which is q = m * c * ΔT, where q is the heat flow, m is the mass, c is the specific heat capacity, and ΔT is the change in temperature.
Recognize that all containers have water at the same initial temperature (50°C) and will likely cool to the same final temperature, so ΔT will be the same for all.
Note that the specific heat capacity (c) of water is a constant value, approximately 4.18 J/g°C.
Understand that since ΔT and c are constant for all containers, the heat flow (q) is directly proportional to the mass (m) of the water.
Compare the masses of water in each container: 30 g, 40 g, and 120 g. The container with the greatest mass (120 g) will have the greatest flow of thermal energy in the form of heat.
