Atoms of a given element will have the same mass. a: true b: false

False because atom of the same chemical elements do not have the same mass because number of proton in the nucleus is the same for all atoms of the same element but the neutron is not.

Explanation:

conduction is the transfer of thermal energy (heat in transfer) due to collisions between the molecules in the object. collisions between adjacent atoms and molecules transfer kinetic energy from the warmer to the cooler object. the objects must be in physical contact.
