Apiece of iron at 25 °c is dropped into a glass of water at 15 °c. which statement is correct?

heat will flow from the iron to the water in the glass until both reach the same temperature.
heat will flow from the water in the glass to the iron until both reach the same temperature.
the final temperature of the water in the glass and the iron will be 25 °c.
the final temperature of the water in the glass and the iron will be 15 °c.

Heat will flow from the piece of iron, into the the water in the glass balancing out the temperature. Because you release some of the energy into the other causing the temperature to balance out and be the same.

When a piece of iron at 25 degrees Celcius is dropped into a glass of water, whose temperature is 15 degrees Celcius, the heat will flow from the iron to the water in the glass until both reach the same temperature. This is because the one that is warmer would release more energy to the colder one.

lizards have adapted to life in the desert. some desert lizards have toes with spiny scales to them run across the sand without sinking. some use the sand to hide from predators, or to search for small animals that they prey upon.

this is a good question! i'll do some research and come back when i have the answer!
