Gas pressure is caused by the molecules of gas striking the walls of a container, or in the case of Earth's atmosphere, the molecules of air hitting the earth. In a vacuum, there are no gas molecules. No molecules, no pressure.

How you know gas is inside the balloon?
If there were nothing inside the balloon - a vacuum - the balloon would quickly collapse due to the pressure of the atmosphere outside it. A firmer structure might resist the air pressure, but not a balloon.
What is the name of the machine measuring pressure of gas?
Many techniques have been developed for the measurement of pressure and vacuum. Instruments used to measure pressure are called pressure gauges or vacuum gauges.
What is room temperature and pressure?
NIL... Does NOT exist...As there is no medium inside the vacuum.
What is the pressure inside of a container when nitrogen gas is added?
The pressure inside of a container when nitrogen gas is added depends on:what the pressure was before the gas was addedhow big the container ishow much nitrogen gas is addedthe temperature of the gas before it is addedthe temperature of the container and its contents
What causes pressure inside a helium balloon?
The pressure in a container is due to the particles of the gas hitting the inside walls of the container.
Is there inert gas inside a thermometer?
No. The tube inside a thermometer is vacuum. If there was a gas inside, the pressure changes due to temperature changes would cause the liquid inside to expand/contract unevenly.

What is the pressure of a container that has a vacuum inside of it?
Since there's no particles present, there's no pressure.
What gas is inside an RCA big screen TV about 20 years old?
There is no gas inside it is a vacuum tube.
What is the name of the machine measuring pressure of gas?
Many techniques have been developed for the measurement of pressure and vacuum. Instruments used to measure pressure are called pressure gauges or vacuum gauges.
Is a vacuum a force?
a vacuum is simply an empty or almost empty space. The forces that are apparent with vacuums are due to a pressure imbalance between the inside of the vacuum (low pressure) and the outside of the vacuum (high pressure) causing particles to want to migrate to areas of lower pressure. The effect of this pressure difference is often refered to as a vacuum force
What is room temperature and pressure?
NIL... Does NOT exist...As there is no medium inside the vacuum.
In brief what is a vacuum?
A vacuum is a space that contains very few molecules of gas, which results in a very low pressure.
What happens to the pressure of a gas inside of a container if the temperature of the gas decreases?
The pressure of the gas would also decrease.
Explain the principle of operation for the pressure cooker and the vacuum pan in cooking?
Pressure Cooker Operation In pressure cooker,the food is cooked in closed condition ,where,there is pressure valve ,here you are increasing the pressure inside the vessel hence ,pressure inside the pan will be greater than atmospheric pressure,hence the boiling point is reached in less time and cooking takes place faster. Vacuum Pan Here vacuum is opened or reducing the pressure where air inside is removed and hence the product is cooked at lower temperature .More u increase the vacuum,more reduction in pressure and hence longer time to cook ,
What is the pressure inside of a container when nitrogen gas is added?
The pressure inside of a container when nitrogen gas is added depends on:what the pressure was before the gas was addedhow big the container ishow much nitrogen gas is addedthe temperature of the gas before it is addedthe temperature of the container and its contents
What makes a vacuum?
A complete vacuum is created in the absence of matter, especially in gaseous form. The phenomenon of suction generally associated with a vacuum results from a pressure gradient. Since P=nRT/V and there are more moles of gas outside of the vacuum there is also a greater pressure outside of the vacuum.
