Chemical and Nuclear Energy

Front

What is gamma radiation?

Back

Gamma radiation is a type of nuclear decay that is made of pure energy and has no mass or charge.

Front

What does the Law of Conservation of Energy state?

Back

The Law of Conservation of Energy states that energy cannot be created or destroyed, only transformed from one form to another.

Front

What is an alpha particle?

Back

An alpha particle is a type of radioactive decay particle that has a mass of 4 and an atomic number of 2.

Front

How do you calculate the remaining mass after a certain number of half-lives?

Back

To calculate the remaining mass after a certain number of half-lives, divide the initial mass by 2 for each half-life that has passed.

Front

What happens to the temperature of surroundings during an endothermic reaction?

Back

During an endothermic reaction, the surroundings feel cold because the system absorbs heat from the surroundings.

Front

Define nuclear decay.

Back

Nuclear decay is the process by which an unstable atomic nucleus loses energy by emitting radiation.

Front

What is the difference between kinetic and potential energy?

Back

Kinetic energy is the energy of motion, while potential energy is stored energy based on an object's position or state.

Front

What is a half-life in nuclear chemistry?

Back

A half-life is the time required for half of the radioactive atoms in a sample to decay.

Front

What type of radiation is emitted during beta decay?

Back

Beta decay emits beta particles, which are high-energy, high-speed electrons or positrons.

Front

What is an endothermic reaction?

Back

An endothermic reaction is a chemical reaction that absorbs heat from its surroundings.
