What happens to the temperature of a substance while it is changing state? explain.

the temperature of a substance while changing often times while rise or fall depending on what is happening. Say you have an ice cube and you put it into a hot soup to cool the soup down the ice cube melts due to the surrounding temperature. In other cases if you want to cool something hot like say hot water you can 1:put it in a cool place such as a refrigerator or freezer or 2:you can leave it out to cool to room temperature.

If something I said didnt make sense plz dont get mad or anything I am only in jr.high in 8th grade and the school year is still fresh so I'm trying to catch up on somethings.

The answer is S = 0.1528 cal/g °C

Explanation:

By the law of conservation of energy, energy is neither created nor destroyed.

So, energy lost by metal pieces is equal to the energy gained by water in the calorimeter.

Specific heat of water is 1 cal/g °C

⇒ heat energy  Q = mSΔT, where m = mass of a substance

                                                        S = specific heat

                                                        ΔT = change in temperature

Now, the heat lost by metal piece, Q = 72×S×(96-31)

                                                      = 4680×S cal

Heat gained by water, Q = 130×1×(31-25.5)

                                        = 715 cal

⇒ 4680×S = 715.

⇒ S = 0.1528 cal/g °C.
