Everything that has mass and takes up space is called matter.
As the temperature drops, the motion of molecules in a gas slows down. They have less kinetic energy and move at a slower speed.
A plasma is a state of matter in which the atoms are ionized and electrons are no longer bound to their respective nuclei. It is different from a gas because it has a higher temperature and consists of charged particles.
Density is calculated by dividing the mass of an object by its volume. The formula for density is density = mass/volume.
To calculate the density of a cube with a mass of 4.5 g, a length of 2 cm, width of 1 cm, and height of 2 cm, we need to first calculate the volume of the cube. The volume of a cube is calculated by multiplying the length, width, and height. In this case, the volume would be 2 cm x 1 cm x 2 cm = 4 cm^3. Then, we can use the mass and volume to calculate the density. Density = mass/volume = 4.5 g / 4 cm^3 = 1.125 g/cm^3.
Whether the cube will sink or float depends on the density of the fluid it is placed in. If the density of the cube is greater than the density of the fluid, it will sink. If the density of the cube is less than the density of the fluid, it will float.
