Do you find that pie fillings from KFC or McDonald's can be very hot? Many people think so，too.
To find out how hot the fillings can be，a team in China did a test. They found that when taking the pies out of the oven，the average temperature of the filling can be up to 64℃. 1 It keeps the heat for a long time.
An idea in science can tell us why. It's called specific heat capacity（比热容）. 2 A cup has a low specific heat capacity；it doesn't hold much heat and cools down fast. Things with a high specific heat capacity take longer to cool down. Usually，liquids（液体）hold heat longer than solids（固体）. 3
Did you know? 4 That's because hot food can make endorphins（内啡肽）in the brain. This makes people feel happy. Parents often tell you to “eat the food while it's hot”. 5 To make sure the hot food is ready to eat，you can hold the bowl or cup for 5 seconds or more. If this is easy，it means the food inside is ready.
A.Think of something like a cup.
B.What they really mean is to eat the food before it gets cold.
C.This is because the filling is thick and stays inside the pie.
D.Although eating hot food is bad for us，people still like hot food.
E.Specific heat capacity is an idea in science that most of us are familiar with.
F.As a pie's filling has more water than its crust（外皮），it takes more time for the filling to cool down.
