If the mass of a fixed volume of air increases does the density become more or less dense?
If the mass of a fixed volume of air increases, the density of the air becomes more dense. Density is defined as mass divided by volume, so as the mass increases while the volume remains constant, the density increases.
What happens when the volume gets larger and the mass gets smaller?
When the volume increases and the mass decreases, the density of the object decreases. This means that the object becomes less compact or dense for the given volume. The relationship between volume and mass is important when considering the physical properties of an object.
How could you use an inflated balloon to show that decreasing the volume of a fixed mass of air increases its pressure?
By squeezing the inflated balloon, you decrease its volume, forcing the air molecules within to be confined in a smaller space. This creates more collisions with the balloon's surface which increases pressure. As the volume decreases and the number of molecules remains constant, the pressure of the gas increases because the molecules have less space to move around.
How does Charles law make a balloon rise?
Charles' Law states that as temperature of a gas increases, its volume also increases if pressure remains constant. When a balloon is heated, the air inside it warms up and expands, causing the volume of the gas to increase. This increase in volume causes the balloon to rise because it becomes less dense than the surrounding air.
What happens to the magnitude of mass density as the volume of an object becomes greater than its mass?
If the volume of an object becomes greater than its mass, the mass density will decrease. Mass density is defined as mass per unit volume, so if the mass stays the same but volume increases, the density will decrease because there is more volume to spread out the mass.
