The cup of rocks has more mass than the cup of air because it is heavier.
obviously a cup of rocks, assuming the cups are the same size
No, hot air does not weigh more than cold air. In general, air at different temperatures still has the same mass per unit volume, or density. The weight of a given volume of air depends more on its mass and not on its temperature.
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.
No. density is based on molecular mass. Air is considered a gas. Gases have lower densities than liquids at 'room temperature'.
An Arctic air mass is more stable than a tropical air mass because it is denser and colder. Cold air has a higher density and therefore tends to stay closer to the ground, creating a stable atmosphere. On the other hand, tropical air masses are warmer and lighter, leading to more vertical movement and instability.
Since air is matter, it does have mass. So adding its mass to the mass of the balloon would cause the balloon to have more mass. Weight is a measure of the pull of gravity on an object and an object with more mass is "pulled" more, so the balloon with air in it would indeed be heavier than a balloon without air.
Yes, the mass of the balloon increases as you put in more air because air has mass. The more air you add to the balloon, the more mass it will have.
An arctic air mass is typically more stable than a maritime air mass due to its colder temperatures and lower moisture content. The colder air is denser and less likely to rise, leading to more stable atmospheric conditions. In contrast, maritime air masses are warmer and more humid, which can promote convection and instability. This difference in temperature and humidity levels contributes to the overall stability of arctic air compared to maritime air.
an inflated because it takes up more room than a deflated one It depends on how you define the basketball. If you define it as just the rubber, then the mass does not change when it is inflated. If you consider the air inside the ball to be part of the ball then adding more air adds more mass. Mass is "stuff". Air has mass because air is stuff.
if you mean cubic metres bricks have a density of about 2.4 kg/ litre and air is about 1.2 kg/ m3 so 2.4 x 2 = 4.8 metric tons for bricks 1.2 x 6000 = 7.2 metric tons for air therefore air has more mass
A warm air mass can hold more water vapor than a cold air mass. This is because warm air has a higher capacity to hold moisture due to its higher temperature. When warm air cools down, it reaches its dew point and can no longer hold all the water vapor, leading to condensation and possibly precipitation.
The warm air mass
