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

Neutral buoyancy

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.

Neutron explained in an easy to understand way.

Neutron

An uncharged particle in the nucleus of an atom. Neutron. A neutron is a subatomic particle found in the nucleus of an atom that has no electric charge and helps hold the nucleus together.

a natural resource that is consumed faster than it can be created

Nonrenewable resource explained in an easy to understand way.

Nonrenewable resource

A natural resource that is consumed faster than it can be created nonrenewable resource. A nonrenewable resource is something we use that cannot be quickly replaced, like oil or coal.

The removal of a fish from water at a rate that they cannot replenish

Overfishing

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