Question 11
Arun is making a cake. He has some solid materials: flour, sugar, butter and chocolate. He breaks some eggs. These are a liquid.
He changes these materials to make the cake.
First, he makes a mixture of three different materials. He mixes the sugar and butter together, then adds the eggs.
Next, he makes the chocolate melt by making it hot. The solid chocolate changes into liquid chocolate.
Then he adds the liquid chocolate and the flour to his mixture.
Now he heats the mixture in the oven. The heat makes the liquid egg change into a new solid material. This new material holds the other materials together so the cake can keep its shape.
Which material changed from a solid to a liquid when it was heated?
