Answer:
Explanation:
mass = 400 grams * [1 kg/1000 grams] = 0.400 kg
c = 387 Joules / (oC * kg)
Δt = 55 - 30 = 25 oC
E = m*c * Δt
E = 0.4 * 387 * 25
E = 3870 Joules
temperature is defined to be the average kinetic energy.
heat energy tends to flow from higher energy to lower energy systems, so knowing the temperatures of things tells you how heat will flow between them.
