Question

While driving her car on a hot sunny day, a woman was struck in the back of the neck by the dough from an exploding can of Pillsbury biscuits. From the sound it made and the feeling of warm sticky dough on her neck, she thought she had been hit by a bullet! Describe the likely conditions that caused this to happen. Be sure to explain AT THE MICRO scale how the particles were affected.

Answer 1

The woman was likely struck by the exploding dough from the can of Pillsbury biscuits due to the increase in temperature and pressure inside the can, causing it to explode. At the micro scale, the increase in temperature leads to higher kinetic energy of air molecules, resulting in increased collisions and pressure inside the can.

Step-by-step explanation:

The likely conditions that caused the woman to be struck by the exploding dough from the can of Pillsbury biscuits while driving her car on a hot sunny day are related to the temperature and pressure inside the can. When the can is exposed to high temperatures, such as in a hot car, the air inside the can heats up and expands. This causes an increase in pressure inside the can. If the pressure becomes too high, it can cause the can to explode, sending dough flying.

At the micro scale, the increase in temperature causes the air molecules inside the can to gain kinetic energy, making them move faster and collide with more force against the container walls. This increase in pressure can eventually exceed the strength of the can, leading to an explosion. Additionally, the dough inside the can may also expand due to the heat, further increasing the pressure inside the can.

Answer 2

The dough is made from flour sugar, baking soda, sometimes yeast. The sugar is converted into gaseous products including carbon dioxide, CO₂ and alcohols. As more gases are produced, the pressure increases, and according to Charles's law, as the temperature on a sunny day is higher than on a cool day, the pressure of the gases increases further, to the point that the can containing the biscuits can not hold the pressure, leading to an explosion
