EQ: How can heat be transferred from one place to another?
... Did the food cool or did the surrounding air warm? Why? In science, there is no such thing as coldness. Instead, the matter grows colder as thermal energy flows from it and transfers to another object/form of matter. Heat transfer occurs only in one direction. ...

... The specific heat depends on pressure. We will only discuss it at atmospheric pressure. The specific heat is very different for different materials. Water has a very high specific heat of 4186 J/(kg ℃). This means that water can carry much energy without a big increase of its temperature. Thus, wate ...
