The energy inside any system is equal to the energy outside.

The total amount of energy in the universe is steadily decreasing.

Energy can never enter a closed system, nor can it leave a closed system.

The total energy in a closed system is a conserved quantity.

The amount of total energy in the water molecules for all three beakers will increase.

The temperature in all three beakers will eventually be 25ºC.

The beaker at 0ºC will increase to 90ºC.

The surrounding room temperature will eventually be 100ºC.

The heat of the soup and the cold of the water were exchanged, cancelling each other out.

Heat energy went from the soup to the room and from the room into the ice water.

Heat energy went from the ice water to the soup and from the soup to the room.

The low temperature of the water was transferred to the room and from the room to the soup.
