What energy is in a marshmallow?

Now we can calculate the food energy in the marshmallow: The molar mass of sucrose is 342.3 g/mol, so the energy per gram is -5643.8 kJ/mol / 342.3 g/mol = 16.49 kJ/g. In the 7.5 g marshmallow, remembering that 1 dietary Calorie is 4.184 kJ, we have 7.5 g x 16.49 kJ/g x (1 Cal / 4.184 kJ) = 29.6 Cal.

How many joules are in a marshmallow?

The food with the lowest energy content per gram was the marshmallow at 362.3 J/g.

What type of energy does a bent plastic spoon have?

The person’s chemical energy is transferred to the spoon and converted into elastic potential energy. The more the spoon is bent, the more elastic potential energy is stored.

How are potential and kinetic energy used in each catapult?

The catapult works when the potential energy stored in a stretched rubber band is converted to kinetic energy when it snaps back to its loose shape, moving the catapult arm—and the projectile! The kinetic energy of the catapult will give the projectile a force moving up and away from the catapult.

What happened to the energy in the marshmallow?

The science behind roasting marshmallows When you toast marshmallows, the heat causes a chemical reaction producing water molecules, which then evaporate, leaving carbon behind (the blackened part of the roasted marshmallow).

What is the energy that is stored by a catapult called?

For a catapult, potential energy is stored as elastic energy. This energy results from the force put in as the muscu- lar push or pull needed to stretch, bend, or twist some sort of elastic material that is attached to the throwing arm.

What is the energy output of a Cheeto?

The calculations also show that the cheeto gave off -1806.16 Joules and contains 2.3 Calories/gram. Calculations used to determine the Calories per gram in each food sample.

What force causes the marshmallow to shoot out of the cup?

While the marshmallow is in the tube, your blowing increases the air pressure in the tube, creating a force on the marshmallow.

How does a marshmallow catapult work?

When an object IS moving it has kinetic energy. The catapult you make is going to transfer energy from the spring to a marshmallow. The marshmallow will have potential energy until the catapult releases, then the marshmallow will have kinetic energy as it flies through the air.

How is energy stored in a catapult?

Where is energy stored in a catapult?

When you prepare the catapult to launch, you add energy to it. This energy is stored in the launching device as potential, or stored, energy. The catapult you are about to make uses elastic potential energy stored in a wooden stick as you bend it.

Do marshmallows have more energy than TNT?

Did you know that the chemical energy released by burning a marshmallow can be three times more than an equivalent mass of TNT? MinuteEarth dives into these two very different chemical reactions and explains why marshmallows don’t blow up when ignited.
