A compartment within a boat that holds water, which is used to provide stability for a vessel

A compartment within a boat that holds water, which is used to provide stability for a vessel. Ballast water is the water carried in tanks of ships to improve stability and balance during their voyage.

A large water covered area between continents

A large water covered area between continents. Basin. In science, a basin is a depression in the Earth's surface where water collects.

The upward force fluids exert, it keeps objects afloat

The process of a gas changing into a liquid
Watch condensation Simple Definition
A removal of heat, usually resulting in a lower temperature or phase change

A removal of heat, usually resulting in a lower temperature or phase change. Cooling. Cooling is the process of decreasing heat to lower a substance's temperature.

The factor measured at the end of an experiment
Watch dependent variable Simple Definition
The solid form of carbon dioxide

The solid form of carbon dioxide. Dry ice. Dry ice is the frozen form of carbon dioxide and is used to keep things cold without leaving any liquid residue.

A negatively charged particle outside the nucleus of an atom

The top of liquid changing into a gas
Watch evaporation Simple Definition
A phase transition where a liquid turns into a solid

A phase transition where a liquid turns into a solid. Freezing. Freezing is the process where a liquid cools down and becomes a solid as its molecules slow down and arrange into a fixed structure.

The temperature at which a liquid changes to a solid
Watch freezing point Simple Definition
The variable which is manipulated by the researcher
Watch independent variable Simple Definition
An atom of the same element with a different number of neutrons
Watch isotope Simple Definition
Energy released or absorbed by a body during a constant-temperature process

Energy released or absorbed by a body during a constant-temperature process. Latent heat. It is the energy required to change the state of a substance without changing its temperature.

Occurs when an object's density is equal to the density of the fluid in which it is immersed

Occurs when an object's density is equal to the density of the fluid in which it is immersed. Neutral buoyancy. This means the object will neither sink nor float in the fluid.

Watch neutron Simple Definition
a natural resource that is consumed faster than it can be created
Watch nonrenewable resource Simple Definition
The removal of a fish from water at a rate that they cannot replenish

The removal of a fish from water at a rate that they cannot replenish. Overfishing depletes fish populations faster than they can naturally recover.

A graph showing the temperature and pressure at which a substance exists as a solid, liquid, and vapor

A graph showing the temperature and pressure at which a substance exists as a solid, liquid, and vapor. Phase diagram. A phase diagram shows the conditions under which a substance changes states, like solid, liquid, or gas.
