because there is no air
In a vacuum temperature is inapplicable. Temperature is a measure of the kinetic energy of the molecules that fill a defined space. In a vacuum there are no molecules so --- no temperature.
Yes, but the difference is negligible.
A perfect (completely empty) vacuum would have no temperature, since temperature implies movement of particles. However, any real vacuum has some particles (the density is simply less than normal air pressure, for instance); the temperature in this case can vary, just as the temperature of air, or the temperature of water, can vary.
Answer Yes, you can. I think the answer is no. A physical object in a vacuum can have some energy/heat in it, and the energy associated with electromagnetic radiation can have energy/heat associated with it, but the vacuum itself cannot. ______________________________________________________________________ There is no such thing as a vacuum.
I spelt the word "negligible" wrong as I spelt it "negligble."
In an absolutely perfect vacuum, there is no defined temperature at all. The temperature simply doesn't mean anything. Of course, there isn't really anything that is a perfect vacuum.At very high vacuum, at equilibrium, the temperature will be determined by whatever the container holding the vacuum is in thermal contact with. Something inside an imperfect vacuum isn't at any particular temperature -- if it is at equilibrium, it will be at whatever temperature the things around it are at. However, the rate at which is reaches equilibrium with may be very slow because of the vacuum. If it not at equilibrium, then the object in the vacuum will be at whatever temperature it was set at until it reaches equilibrium with the things around it.
Nothing. It continues to propagate at the speed of light, and is not diffracted or distorted except by negligible gravitational effects.
Both time and temperature can decrease the vacuum draw of an evacuated tube. Hence the provided expiration dates and storage temperature of tubes. The vacuum of a tube will decrease if it is too old or if stored at a colder temperature than recommended.
Quality vacuum gage is required ;-) engine at running temperature around 18 to 20 inches Hg = vacuum
Temperature is the vibration of particles.In a true vacuum there are no particles.Therefore, a true vacuum cannot have a temperature other than 0K (approx-273C) i.e. absolute zero
When engine temperature rises, the brake sees vacuum and pulls the choke open.
because they decompose at higher temperature.. under vacuum they can be boiled at lower temperature than their boiling point
