NGSS.MS-PS3-4

A process of heat transfer in which the molecules in substances directly transfer kinetic energy to each other through contact.

• conduction

• convection

• radiation

• thermal

A process of heat transfer in which warmer and cooler fluids, such as water, air (gases) or magma, move due to differences in density.

• conduction

• convection

• radiation
