B. Styrofoam cups tip over more easily than ceramic mugs.
O
C. Ceramic mugs are more cost effective than Styrofoam cups
because they can be reused.
O
D. Ceramic mugs are better for the environment than Styrofoam

Respuesta :

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.
