Readers ask: Why Does Popcorn Pop Science Fair Project?

What puts the pop in popcorn science fair project?

Lesson Plan. Popcorn pops because each kernel has a tiny bit of water inside it. When the kernels are heated, the water inside heats up to the point where it exerts enough pressure to burst the kernel open. The soft material inside puffs up as it explodes.

What is the science behind popping popcorn?

The reason why popcorn pops is the water trapped inside its kernel. If the kernel is heated to a high enough temperature, this water will transform into steam. With high temperatures, the starch gelatinizes and then expands with the rapid burst of the kernel.

Why does popcorn pop thermodynamics?

Popcorn is the funniest corn to cook, because it jumps and makes a ‘pop’ sound in our pans. When the popcorn temperature exceeds 100°C, its water content (moisture) boils and reaches a thermodynamic equilibrium at the vapour pressure, as in a pressure cooker [6]. Above a critical vapour pressure, the hull breaks.

Can you pop popcorn over a candle?

put a small amount of oil in the tray and enough popcorn to cover the bottom of the tray. then hold the tray by the canes over the lit candles. it will take a while but the popcorn will eventually start popping. keep over the heat until the popping stops.

Does soaking popcorn make it pop better?

Perfect Popcorn The Internet-approved tip is as follows: Soak popcorn kernels in water for 10 minutes, then drain and pop as normal. The theory is that the extra moisture helps produce fluffier puffs.

Why is my popcorn not popping?

Popcorn kernels will not pop if they contain too little or too much water moisture inside the kernel. The popcorn kernels which do pop have 14-15% moisture in the hull and anything less or more will cause the popcorn kernel to not explode.

Is popcorn kernel a living thing?

Answer 2: Popcorn kernels contain water, as do all living things. When you heat them, the water boils and turns to vapor (gas), but the gas has no where to go because it’s inside of the kernel.

What brand of popcorn pops the most?

Why do some brands of popcorn pop better?

The crystalline sheet is tighter than the original cellulose, which is only partially ordered. “It forms a better barrier,” he says, “and keeps moisture in the kernel better.” Why some popcorn kernels are better poppers than others depends on how orderly these crystalline sheets are, the researchers found.

Is making popcorn an entropy?

Entropy measures how much thermal energy or heat per temperature. Campfire, Ice melting, salt or sugar dissolving, popcorn making, and boiling water are some entropy examples in your kitchen.

Is the entropy of a bag of popcorn greater than less than or equal to the entropy of the kernels of corn before popping explain?

Is the entropy of a bag of popcorn greater than, less than, or equal to the entropy of the kernels of corn before popping? Entropy of the popped corn is greater because popping the corn is an irreversible process.
