Question

351 Joules of energy was released when a 12 gram sample of unknown metal with an initial temperature of 90 °C was cooled down to 25 °C Describe the direction of heat flow between the metal and the water. (4 pts)

Answer 1

Naturely, the direction of the heat flow is from zone of high temperature to zones of low temperature. Hence, the direction of heat flow is from the sample of unknown metal and surrounding water until thermal equilibrium in the water-sample system is reached.

Step-by-step explanation:
