Answer- when heated, the elections in atoms absorb energy and are elevated to higher energy levels.
Answer:
aluminum (solid)
Explanation:
Solids have fixed shape and volume at room temperature.
Matter is defined as any substance that has weight and occupies space. There are three main classes of matter;
- Solid
- Liquid
- Gas
Solids are particles have strong attractive force between them. This confers a fixed shape and volume on them.
Liquids are mostly fluids that takes up the shape of containers they occupy. The have intermediate strength of attractive forces.
Gases have weak forces and do not have fixed shape or volume. They take up the shape of any container they are introduced into.
A should be the products and D should be the reactants. So D should be the answer.
The correct answer would be an atom.
Answer:
In general, liquids tend to get “thinner” when their temperature increases. For example, honey and oil tend to flow better at higher temperatures. Therefore, increasing temperature decreases viscosity. In general, the liquids tend to expand when their temperature increases
