How does the pressure inside a can compare to the pressure outside the can if it's in hot water?
It depends on your test conditions, but let's assume a basic coffee can.
If it is unsealed containing only room air in your kitchen, there would be no fundamental difference in pressure between the inside and outside of the can in a sink of hot water. The air both inside and immediately outside of the can will be comparably heated by the water, therefore the air density and pressure will be equal.
If it is sealed air-tight with room air just prior to putting it in the water, then the pressure inside the can will rise compared to the outside.
But, if you seal the can with a perfect interior vacuum prior to putting it in the hot water, there will never be a pressure difference because there was no interior pressure from the start. Only the water and air pressure outside of the can can change.
Take the same can to the ocean, seal it air-tight with sea-level air, then submerge the can 30-ft. The pressure outside of the can will be twice as high at 28-lbs. per square inch as inside at 14-lbs. per square inch, the nominal pressure of air at sea level. The deeper one goes, the more likely the can will eventually implode.
Here's the kicker. In all these cases, there is actually a very, very, very small probability that the results, in each case, will be the opposite. The reason is a little ol' phyiscs theory called Qantum Mechanics, which essentially says ALL things are possible, no matter how improbable.

Why does toilet water move when it is windy?
When it is windy, the air pressure outside the toilet bowl changes, causing the water level inside the bowl to rise or fall. This movement of air pressure creates a difference in pressure between the inside and outside of the bowl, leading to the water moving.
Why can water get into the inverted tumbler only when it is tilted slightely?
Water can only enter the inverted tumbler when it is tilted slightly because this creates a lower air pressure inside the tumbler. When the tumbler is tilted, the air pressure above the water level decreases, allowing atmospheric pressure to push water into the tumbler to equalize the pressure inside and outside.
What happens to the level of the water in the straw when the water in the bottle is cooled?
When the water in the bottle is cooled, it contracts and creates a lower pressure inside the bottle. The higher atmospheric pressure outside the bottle pushes the water up through the straw to equalize the pressure, causing the water level in the straw to rise.
What happens when a hot soda can is placed in cold water in the hot soda can in cold water experiment?
When a hot soda can is placed in cold water in the hot soda can in cold water experiment, the can undergoes a rapid cooling process. This causes the air inside the can to contract, creating a lower pressure inside the can compared to the outside. As a result, the higher pressure outside the can pushes the can inward, causing it to crush or implode.
Why does the water in my toilet move when it's windy?
When it's windy, the air pressure outside your home changes, causing the air pressure inside the plumbing system to also change. This change in pressure can make the water in your toilet bowl move or ripple.
Why does the can crush when placed in cold water?
When a can is placed in cold water, the air inside the can cools down and contracts, creating a lower pressure inside the can compared to the outside. The higher pressure outside the can then crushes the can as it tries to equalize the pressure inside and outside.
When the water level is higher inside than outside the flask is the gas pressure in the flask higher than lower than or the same as the atmospheric pressure?
When the water level is higher inside than outside the flask, the gas pressure in the flask is lower than the atmospheric pressure. This is because the weight of the column of water inside the flask creates an additional pressure on the gas inside, reducing its pressure relative to the atmospheric pressure outside.
Compare the rate of water flow on the inside of a meander curve with that on the outside of the curve?
No
When the water level is higher inside than outside the flask is the gas pressure in the flask higher or lower or the same as the atmospheric pressure?
When the water level is higher inside the flask than outside, the gas pressure in the flask would be lower than the atmospheric pressure. This is because the water exerts a partial vacuum on the gas in the flask, reducing its pressure compared to the external atmospheric pressure.
Why does toilet water move when it is windy?
When it is windy, the air pressure outside the toilet bowl changes, causing the water level inside the bowl to rise or fall. This movement of air pressure creates a difference in pressure between the inside and outside of the bowl, leading to the water moving.
When 1 straw is in the glass of water and the other is outside the glass why doesn't any water come in when sucked on both straws?
First consider just sucking on a straw. You are creating a lower air pressure in your lungs by performing a volume expansion. This internal low pressure doesn't last long because outside air rushes in to equalize the pressure both inside and out. You cannot suck in enough air to serious or even detectiably alter the pressure of the whole atmosphere. Second consider sucking on a straw in a glass of water. You create a low pressure region inside of you by performing a volume expansion. The outside air wants to equalize the pressure both inside and out but there's a big hunk of water in the way. So the outside air pressure pushes the water up the straw by pushing down on the surface of the water. The height that the water goes up to depends on the weight of the column of water in the straw and the difference between the outside and inside air pressure. In other words how high up the water goes depends on how hard you inhale (work). Thirdly consider two straws one inside a glass of water, the other free to the outside air. When you inhale you perform a volume expansion which creates a low pressure region inside of you. The outside air rushes in the straw that is free to the outside air and equalizes the air pressure both inside and outside. Consequently there is no pressure difference that would cause the water to be forced up the straw.
What are the two types of outside pressures that may act on the outside of an organism?
Atmospheric pressure out side the body and hydrostatic pressure for animals that live in water
Why does a hot can crush when placed in cold water?
When a hot can is placed in cold water, the air inside the can cools down and contracts, creating a lower pressure inside the can. The higher pressure outside the can then crushes it.
Why did the water rush into the erlenmeyer flask when it was submerged in the cold water?
1. When the flask was placed into the cold water, the colder air molecules in the flask move slower, putting out less pressure. With the decrease in air pressure inside the flask, the now greater pressure outside pushes water into the flask until the pressure inside equals the pressure outside.
Why was it necessary to match the water levels inside and outside the cooled flask before removing it from the water bath?
So to equalize the pressure inside the flask with that of the atmosphere.
Why aren't organism on the seafloor crushed by water pressure?
Pressure on the inside is the same as the pressure on the outside. No different from why doesn't the air pressure of 15 psi not squeeze us flat.
If a tin is filled with hot water and sealed then covered with cold water What causes the tin to become dented?
The outside air pressure dents the tin. The water or air inside a sealed metal container will contract when cooled from the outside (by conduction through the can). When it was sealed, the pressure on the inside was the same as on the outside. But the contraction reduces the pressure on the inside, causing the external air pressure to squeeze the can, and possibly cave it in. This is widely demonstrated in another experiment using dry ice. A sealed gasoline can of about a gallon (4 liters) is placed on a dry-ice bed and cooled until the outside air pressure crushes the can.
