Exploring Energy and Thermodynamics Concepts

Front

What does the conservation of mass state in a chemical reaction?

Back

The mass of the reactants equals the mass of the products.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of motion.

Front

What is potential energy?

Back

Potential energy is the energy of position.

Front

How do temperature and heat differ?

Back

Temperature is a measure of the average kinetic energy, while heat is the transfer of energy.

Front

What is a neutron?

Back

A neutron is a subatomic particle found in the nucleus that has no charge.

Front

What is conduction?

Back

Conduction is the process of energy transfer through direct contact between particles.

Front

What is the formula for kinetic energy?

Back

Kinetic Energy (KE) = 1/2 mv², where m is mass and v is velocity.

Front

What is the formula for potential energy?

Back

Potential Energy (PE) = mgh, where m is mass, g is acceleration due to gravity, and h is height.

Front

What is thermal energy?

Back

Thermal energy is the total energy of all the particles in an object.

Front

What is the difference between an endothermic and exothermic reaction?

Back

Endothermic reactions absorb energy, while exothermic reactions release energy.
