What else can I help you with?
When you heat popcorn it pops because it loses water explosively Assume a kernel of corn weighing 0.124g weights only 0.106g after popping Calculate the percentage of water in the kernel of corn?
14,5 % water
When popcorn is heated over a flame the kernel burst open Why does this occur?
The air and water vapor inside the kernel is expanding.
What compound makes popcorn explode?
The compound known chemically as "H20" - water. There is a tiny drop of water at the heart of every corn kernel. When heated, it turns to steam, and turns the corn kernel "inside-out" - that's popcorn.
Is there really water in popcorn kernels?
All popcorn contain a small amount of water. When the popcorn gets heated the water inside the popcorn kernel turns to steam. The steam then starts to pressure the kernel shell and soon bursts making the kernel inside out, and the soft stuff inside the kernel puffs.
What batch of popcorn kernels would produce more popcorn a batch of kernels soaked in water or a somewhat dried out batch?
I wouldn't advise soaking your popcorn. Popcorn "pops" because 1) there's water INSIDE the kernel and 2) there's a hard shell to hold the water in. Together, these make it possible to build up STEAM inside the kernel until it bursts the shell, effectively turning the kernel inside-out, puffing it up in the process.
How does seeesd turn into popcorn?
Inside each kernel of pop corn there is a very small amount of water. When the kernels get hot the water expanded as steam and explodes the kernel.
How does moisture get in popcorn?
Moisture inside popcorn kernels turns into steam when heated, causing the kernel to pop and expand. This steam creates pressure inside the kernel until it bursts open, resulting in fluffy popcorn.
What do you heat to get a piece of popcorn?
kernel
How does changing water into gas in a popcorn kernel model the expansion of dissolved water in magma?
Changing water into gas in a popcorn kernel demonstrates the expansion of water when heated, similar to how dissolved water in magma expands when heated. As the water molecules heat up and turn into gas in the kernel, they create pressure that causes the kernel to pop. Similarly, when magma containing dissolved water heats up, the water expands and creates pressure, leading to volcanic eruptions.
The actual piece of popcorn is called what?
It is called "a piece ( or kernel) of popcorn," or more properly if less often, " a popped kernel," or "a popped corn."
What ingredient makes microwave popcorn pop?
The popcorn kernels all contain a drop of water that turns to steam when it is heated. The steam expands the kernel until it pops.
What is a popcorn kernel?
A dehydrated piece of corn.
