Exploring Thermal Energy Transfer

What is the second law of thermodynamics primarily concerned with?

Which term describes the process by which thermal energy moves from a hotter object to a cooler one until equilibrium is reached?

If two objects at different temperatures are placed in contact within a closed system, what will eventually happen to their temperatures?

A metal block at $$80^\circ$$ C is placed in water at $$20^\circ$$ C inside a closed container. Which statement best describes the energy transfer?

If a system receives $$E_{in} = 80$$ J and releases $$E_{out} = 30$$ J, what is the net change in energy of the system?

If the energy of one component in a system increases by $$25$$ J and the energy of another component decreases by $$25$$ J, what does this indicate about the energy flow in the system?

You are given the following data for a closed system: Component A loses $$15$$ J of energy, Component B gains $$10$$ J, and $$5$$ J flows out of the system. Using a computational model, what is the net change in energy for the system?

Match each law of thermodynamics.

Heat transfers from an area of (a)   temperature to an area of (b)   temperature.

Heat is ​ (a)   transferred between objects because of a difference in their ​ (b)   . It moves from an object with ​ (c)   energy to ​ (d)   energy.
