When cold water is poured over a tightly corked tin can containing steam the tin can gets crushed What crushes the tin can?
Air pressure from outside and vacuum effect from inside.
How much oxegyn can a astronaut suit contain?
Oxygen (O2) is necessary to the respiration and the survival of astronauts in the near vacuum of space. Astronauts does not have the breathable atmosphere on Earth in space. The space suit protects them from the lethal cold and vacuum of space by keeping him in temperature controlled and pressurized environment.
When astronauts travel in space they must wear special helmets. Why?
The helmets are part of their space suits. They do not normally wear space suits unless they are going outside the spacecraft. Since there is no air outside and it can be very cold or hot. They need the suits to breathe and to protect them from the heat or cold and the vacuum of space which would kill them.
What is the name of the vacuum from the movie wall-e?
The vacuum's name is VAQ-M.
Are pressure and vacuum inversely proportional or directly?
I am not sure if they are proportional, but they are inversely related. High pressure makes a low vacuum, and low pressure makes a high vacuum.
Do all vacuum tubes light up?
No, there are some cold cathode vacuum tubes. These do not light.
Why can cold water in an uncapped vacuum flask still stay cold?
It will certainly not stay cold as long as if it were capped.
How does vacuum flasks keep hot liquids hot and cold liquids cold?
by inhibiting heat conduction
Why do not you turn the ice to vapor in a vacuum chamber at a vacuum 1 torr?
Because it is not either cold enough or hot enough.
What word fits into container vacuum hot and cold?

Why does the ac go from cold to hot after a minute or so. i can here a flap or vent close when it goes from cold to hot..?

Why is the inside of a vacuum flask shiny?
To reflect radiation back, where from it is coming. So hot contains will remain hot and cold will remain cold.
How does a vacuum bottle keep food hot or cold?
The main idea is to reduce the heat transfer out of the vacuum bottle, or into it. A vacuum greatly reduces the transfer of heat by conduction and convection, while the mirror reduces heat transfer by radiation.
