Temperature can affect a couple of different variables in a ball to alter the distance it will travel from an impact. For inflated balls, the temperature can change the air pressure inside the ball giving an over inflated effect if it was warmed, or and under inflated effect if it was cold. (Have you ever tried dribbling a basketball without enough air in it?) The amount of air pressure then is directly proportional to the temperature of the air inside.
Both would weigh the same, as a pound of cold air and a pound of warm air both have the same weight. Temperature does not affect the weight of the air.
You can blow up a balloon and then weigh the balloon and minus it from the original weight of the balloonAnswer:Weighing air is problem because of the buoyant forces at work. If you have flattened paper bag and weigh it then open it up (effectively filling it with air), and weigh it again you find the weight is the same. In the case of a balloon, a filled balloon will weigh more than an empty balloon as it is filled with compressed air due to the tension of the balloon skin. You have no idea of the volume of room pressure air is in it.To determine this you could inflate the balloon with known volume of air using bicycle pump. Simple math would identify the volume transferred with each stroke. By knowing the weight before filling, the weight after filling, and the volume transferred it would be possible to calclate the weight per meter (or cubic foot) of room pressure air.
No, warm air and cold air exert different pressures due to their different densities, but the weight of a volume of air is determined by its mass. Therefore, a mass of warm air does not weigh more than a mass of cold air, assuming the volumes are the same.
10 mL of helium at standard conditions (STP) would weigh approximately 0.0125 grams.
