Which is an example of radioactivity that occurs when a neutron is converted to a proton and an electron is emitted from the nucleus?

Beta minus decay

Explanation:

Beta decay is due to a weak nuclear interaction, it takes place in the atomic nucleus and occurs when a neutron is converted to a proton, or a proton into a neutron. When a neutron is converted to a proton an electron and an electronic antineutrino are emitted from the nucleus, this is called beta minus decay.

this means that the temperature of both substances will be equal
