Exploring Energy and Thermodynamics Concepts

Front

What is an Isotope?

Back

An element with a different number of neutrons than the most common version of that element.

Front

Describe the basic structure of atoms.

Back

Atoms consist of protons, neutrons, and electrons.

Front

How does energy flow between objects of different temperatures?

Back

Energy flows from a hotter object to a cooler object.

Front

Which subatomic particle is found in the nucleus and has no charge?

Back

Neutron.

Front

What happens when two objects of different temperatures are thermally connected?

Back

The objects will reach a common temperature.

Front

What is the definition of thermal equilibrium?

Back

Thermal equilibrium is the state in which two objects in thermal contact no longer exchange energy, as they have reached the same temperature.

Front

What are protons?

Back

Protons are positively charged subatomic particles found in the nucleus of an atom.

Front

What are electrons?

Back

Electrons are negatively charged subatomic particles that orbit the nucleus of an atom.

Front

What is the role of neutrons in an atom?

Back

Neutrons help stabilize the nucleus of an atom by offsetting the repulsive forces between protons.

Front

What is energy transfer?

Back

Energy transfer is the process of energy moving from one system or object to another.
