Final answer:In a vacuum, an object does not havebuoyant forcebecause of the absence of fluid. But it retains its mass and temperature, which depend on an object's properties, not on the environment's conditions. As for weight, it remains present due to gravity despite the absence of air resistance in a vacuum.Explanation:In avacuum, anobjectdoes not have a buoyant force. This is because buoyant force is an upward force exerted by a fluid that opposes the weight of an immersed object. In a vacuum, there is no fluid or air to exert this buoyant force, thus an object doesn't experience buoyancy.However, the object still retains its mass in a vacuum, because mass is an intrinsic property of an object and does not rely on external conditions. Besides, the temperature of an object remains unchanged as it refers to the kinetic energy of the object's molecules, which are unaffected by the presence or absence of an external medium such as air or fluid.Lastly, weight is a force that results from the gravitational attraction between an object and Earth. In a vacuum, gravitational force still applies so an object still has weight, although a vacuum ensures no resistance to an object's fall.Learn more about Vacuum Physics here:brainly.com/question/32600944#SPJ11...
