When carbon-14 undergoes beta decay, it becomes which of the following? oxygen-13 + a beta particle nitrogen-14 + a beta particle carbon-13 + a beta particle boron-14 + a beta particle?

nitrogen-14 + a beta particle

Explanation: General representation of an element is given as:

where,

Z represents Atomic number

A represents Mass number

X represents the symbol of an element

Beta-decay: In this process, a neutron gets converted into a proton and an electron releasing a beta-particle. The beta particle released carries a charge of -1 units and no mass.

answer: the rate of diffusion increases with increase in temperature.

increase in temperature, increases the molecular/particles speed (kinetic energy. diffusion means movement of particles through the material.

generally, the heavier the particle the more it interacts with the environment and more the temperature matters. so higher temperature results in higher diffusion.
