Solid is the coldest state of matter.

Liquid turns into gas through condensation.

Boiling point is a chemical property.

"The mouse is small" is a qualitative assessment.

A piece of metal is placed inside a test tube along with a liquid. After a few seconds bubbles begin to form and soon steam starts to form on the surface of the liquid. This is a physical change.

George is making salad dressing. In order to do so he has to mix vinegar and oil. However, when he pours both substances into the same container they separate and the oil floats to the top. What can you conclude about the density of both materials?

If the mass of a substance is 10g, and the density of a substance is 5g/mL, the volume of the substance is [blank_start]2mL.[blank_end]

An Alloy is a solid pure substance.

Check of the properties of all metals.

A glowing split was exposed to a gas. Upon exposer it caught on fire. What was the gas?

Protons have a [blank_start]positive charge[blank_end], are located in the same place as a [blank_start]neutron[blank_end], and have a relative mass of [blank_start]1 amu[blank_end]. Neutrons have [blank_start]no charge[blank_end], are located in the nucleus, and have the same mass as a [blank_start]proton[blank_end]. [blank_start]Electrons[blank_end] have a [blank_start]negative[blank_end] charge, are located in the [blank_start]orbits[blank_end], and have a relative mass of [blank_start]1/2000[blank_end] amu.

What is the Bohr-Rutherford model of sodium?

Label the solar system.

Gravity is important.

The hottest stars are the Blue/M class.

Why do we have seasons?

A solar eclipse is when light from the sun is blocked from getting to the earth by the moon.

Once a yellow dwarf starts to run out of fuel it will shrink.

When looking at stars, scientists observed that many of their spectral lines appeared to be [blank_start]red-shifted[blank_end]. This means that the stars were moving [blank_start]away[blank_end] from us. This was taken as evidence of the universe expanding, and the [blank_start]Big Bang[blank_end].

Opposite charges [blank_start]attract[blank_end]. Like charges [blank_start]repel[blank_end].

Charging by friction is when one substance has a charge, the other is neutral, and the charges flow from one to the other.

A dry cell battery refers to

Ohms law states that: [blank_start]Voltage[blank_end]=CurrentxResistance

How many years does it take for the population to rach the carrying capacity?
