What are the 5 types of matter?
sdas [7]

The five types of states of matter are solid, liquid, gas, plasma and Bose-Einstein condensate.

Solid objects do not move a lot relative to themselves. Their molecules stay stacked neatly with no intermolecular spaces. They do not have much energy, or heat hence the molecules in solid state don't show movement.

Liquid state have more heat and more energy and a little more intermolecular space than solid. Their molecules are no longer stacked neatly due to presence of air capsules, but they still touch each other. Their structure is uncertain and can flow, their shape will alter quickly and dramatically with outside forces, but they will essentially remain a single mass unless pushed apart.

Gasses have even more energy than liquid and solid. Due to presence of high intermolecular spaces they flow like liquids, but are even more susceptible to the forces acting on them. Their molecules don’t touch each other, but are still close enough to bounce into one another frequently.

Plasma is the state of matter which is like a gas on steroids. Molecules of plasma might start in the same area, but rarely touch each other. Plasma molecules have lost electrons, and have become charged. Plasma molecules set other things on fire, and even vaporize them.

Bose-Einstein condensate or BEC was first created by scientists in the year 1995. This was created using a combination of lasers and magnets, Eric Cornell and Carl Weiman, scientists at the Joint Institute for Lab Astrophysics (JILA) in Boulder, Colorado, cooled a sample of rubidium to within a few degrees of absolute zero.

If the half-life of a sample of a radioactive substance is 30 seconds, how much would be left after 60 seconds? A. one-fourth B.
Basile [38]
m=m_{0}*(\frac{1}{2})^{\frac{60}{30}}\\\\
m=m_{0}*(\frac{1}{2})^{2}\\\\
m=\frac{1}{4}m_{0}

Base your answer on the information below. The hydrocarbon 2-methylpropane reacts with iodine as represented by the balanced equ
Kryger [21]

Answer:

See explanation

Explanation:

The boiling point of a substance is affected by the nature of bonding in the molecule as well as the nature of intermolecular forces between molecules of the substance.

2-methylpropane has only pure covalent and nonpolar C-C and C-H bonds. As a result of this, the molecule is nonpolar and the only intermolecular forces present are weak dispersion forces. Therefore, 2-methylpropane has a very low boiling point.

As for 2-iodo-2-methylpropane, there is a polar C-I bond. This now implies that the intermolecular forces present are both dispersion forces and dipole interaction. As a result of the presence of stronger dipole interaction between 2-iodo-2-methylpropane molecules, the compound has a higher boiling point than  2-methylpropane.

Which of the following are phase changes? Select all that apply.
kogti [31]
A, B, C, and D, because they are changing from a solid to a liquid, liquid to solid, and solid to gas. Phase changes are when a solid, liquid, or gas, turns into a solid, liquid, or gas. Ex. Ice melting is a solid changing into a liquid. Hope this helps!
