A and C are the correct answers. Because there is no gravity to pull fluids down, they are in your face and hands more than normal. Our bones and muscles become weaker because without gravity objects lack weight.
Answer: Filtration
Explanation:
Heterogeneous mixtures : It is a mixture that has non-uniform composition throughout the solution and the particle size or shapes are also different. There is a physical boundary between the dispersed phase and dispersion medium.
Homogeneous mixtures : It is a mixture that has uniform composition throughout the solution and the particle size or shapes are not different. There is no physical boundary between the dispersed phase and dispersion medium.
Filtration is a type of mechanical separation process in which the smaller particles are separated from the bigger particles through the filter paper where small particles pass through the fine holes of filter paper and the left ones remain on the filter paper.
In the given heating curve, Particles of the substance have the most kinetic energy when the substance is (a) 1. A gas. The part of the graph that represents where the substance has the least amount of potential energy is labeled (b) 1. Solid.
<h3>What is Heating curve ?</h3>
The heating curve is the relationship between the heating system supply temperature and the outside air temperature.
Gas molecules have the highest average velocities among the three states of matter so gas has the highest kinetic energy.
During freezing, a substance loses a lot of potential energy so solid has the least potential energy.
Hence, In the given heating curve, Particles of the substance have the most kinetic energy when the substance is (a) 1. A gas.
The part of the graph that represents where the substance has the least amount of potential energy is labeled (b) 1. Solid.

Answer:
The kinetic theory of matter explains that all matter is made of particles which are constantly moving/have energy. The energy varies depending on the temperature of the matter, therefore determining if the matter is solid, liquid, or gas. When the energy of a particle is increased or decreased, a phase change can occur.
