What is the molecular arrangement in a solid?

Back

In a solid, molecules are closely packed together in a fixed arrangement, vibrating in place.

Front

What is the molecular arrangement in a gas?

Back

In a gas, molecules are far apart and move freely, filling the entire volume of their container.

What is convection?

Back

Convection is the transfer of thermal energy through the movement of fluids (liquids and gases) caused by differences in temperature.

Front

What is radiation?

Back

Radiation is the transfer of thermal energy through electromagnetic waves, such as sunlight.
