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.

Why steam turbine exhaust temperature rise during start up?
exhaut steam temperature raising due to cooling water inlet temperature raise vacuum pullying is not proper scale formation in turbine blades
What factors affect condenser vacuum?
Condenser vacuum is primarily affected by factors such as the temperature of the cooling water, the presence of non-condensable gases, and the efficiency of the condenser design. High cooling water temperatures can reduce the heat transfer efficiency, leading to a higher pressure in the condenser. Additionally, non-condensable gases, like air, can accumulate and impede the vacuum, while a well-designed condenser enhances heat exchange, maintaining optimal vacuum levels. Regular maintenance and proper operation also play crucial roles in sustaining effective condenser vacuum.
What does double glazing windows do?
Double glazing keeps your house at a constant temperature because there is a vacuum in between two layers of glass. There is no air or particles of any kind in a vacuum, so heat cannot be conducted through it. Therefore the heat inside the building cannot be lost to outside, and vice versa
Was the vacuum invented by ives mcgaffey?
It was I. I invented the vacuum. Who am I? Your mother.
IS vacuum tube ohmic?
Vacuum tubes are generally not considered ohmic devices. Ohmic materials exhibit a linear relationship between voltage and current, described by Ohm's law (V = IR). In contrast, vacuum tubes operate based on thermionic emission and can exhibit nonlinear characteristics, meaning their current-voltage relationship can vary based on factors like temperature and applied voltage. Thus, they do not maintain a constant resistance across different operating conditions.
What is the temperature inside of a vacuum?
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.
Energy cannot be transferrd in vacuum what is the temperature of vacuum?
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.
What is the temperature in a vacuum?
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.
Why is the temperature of vacuum negligible?
because there is no air
What decreases the vacuum draw of evacuated tube?
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.
If sitting in idle vacuum can be at?
Quality vacuum gage is required ;-) engine at running temperature around 18 to 20 inches Hg = vacuum
Does the temperarure changes in vacuum when sun light passes through it?
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
How the vacuum break works?
When engine temperature rises, the brake sees vacuum and pulls the choke open.
Why higher boiling hydrocarbonates are distilled under vacuum condition?
because they decompose at higher temperature.. under vacuum they can be boiled at lower temperature than their boiling point
What is the proper way to take the temperature of vacuum packed food?
The proper way to take the temperature of vacuum packed foods is with a metal stem thermometer. To take the correct temperature, put the thermometer in the center of the food.
How long can defrosted vacuum sealed beef be kept at room temperature?
It shouldn't be left at room temperature. The vacuum packaging sets up a perfect environment for Clostridium botulinum.
What is the right way to measure the temperature of MAP or vacuum-packed foods?
The proper way to take the temperature of vacuum packed foods is with a metal stem thermometer. To take the correct temperature, put the thermometer in the center of the food.
