Explanation:
Coffee cools more quickly in a ceramic mug than in a Styrofoam
cup.
Explanation:
Styrofoam is a good insulator, thus for keeping the coffee warm for longer, it is a good choice than ceramic. The process involved in the control of heat dissipation employs the fact that the vapours in the form of gas are entrapped within, they lessen the conduction process between the molecules as a result molecules do not collide hence no energy releases or exchange takes place.
Styrofoam cups are made up of polystyrene foam. As a result of high insulation at styrofoam body conduction is not possible so coffee is warmer for longer.
D. Catalysts get used up in the formation of the product.
Catalysts are never used up in a reaction.
