"Newton's law of cooling states that a hot object will transfer its heat to a cooler object faster depending on how cold that object is. Stated mathematically, it says that the rate of change of the h ...
"Thermal energy transfer involves the transfer of internal energy. The three types of thermal energy transfer are conduction, convection and radiation. Conduction involves direct contact of atoms, con ...

"In the greenhouse effect, the gases of which our atmosphere is composed absorbs the thermal energy that the Earth radiates and reflects some of it downwards again, towards the Earth, effectively trap ...
"Freezing is the transition of a substance from the liquid to solid state of matter. Most substances are more dense in their solid form, with the exception of water which expands as it freezes. The op ...

"Evaporation is the vaporization of liquids at the surface. Evaporation is related to vapor pressure and when the surface of a liquid gets warm, the additional energy is enough for it to vaporize. Eva ...

"Convection is the movement of warm particles within fluids. Convection is often found in the air as heated air rises and cool air falls. This is because hot molecules spread apart, making them less d ...

"Condensation is the change in phase of a gas upon the surface of a solid due to its loss of energy to that solid. Water droplets often form on the surface of cool substances because the water vapor i ...
