You start with two beakers that both contain 50 grams of solution. Beaker 1 contains water (the specific heat capacity for water is approximately 4.2 J/g °C). Beaker 2
contains alcohol (the specific heat capacity is approximately 2.2 J/gºC). Initially, both
solutions are at 20°C (about room temperature). Both beakers are then heated to 90°
C.

Which process does not require the presence of a physical substance in order to transfer heat? air in the atmosphere is heated by the ground. this warm air then rises, and cooler air falls. this is an example of what type of process? how is conduction different from radiation?

Asubstance is held in an open container. its particles move past one another at random speeds but do not leave the container. heat is removed from the system, and the particles slow down. when enough heat is removed, the particles no longer have enough speed to overcome the weak attractive forces between them. when this happens, the substance enters its solid state. the process described above is known as .
