CAPT Science Practice Test

In 1742, Benjamin Franklin designed a wood-burning stove to heat rooms. The front of the stove was open, allowing heat to spread into a room. The back of the stove was closed, but had an air intake that increased air circulation. Fires lit in traditional fireplaces received less oxygen than those lit in Franklin stoves. What effect does a lit Franklin stove have on the air molecules in a room?

Decreases their mass

Increases their speed

Decreases their volume

Increases their energy loss
