### Thermodynamics!!!!!

How do you increase surface area?

### Thermodynamics!!!!!

• In other words, heat goes from the warmer object to the cooler object, through the areas of contact (Boundaries), until they reach the same temperature.

### Exit Ticket!

• 1. How can the surface area of an object be increased without increasing the volume of the object?

• 2. In addition to increasing surface area on motorcycle engines and heatsinks to refrigerate the device, when else would it be beneficial to increase the surface area of an object without increasing its volume?
