Answer:

At 15.2°C. Kinetic energy of molecules highly depends on the temperature - the warmer it is, the faster the molecules will move, especially in fluids (gases and liquids). If we consider that the formula for average kinetic energy of molecules is:

Ek = 3/2*k*T where k is Boltzmanns constant and 3/2 is, well, 3/2, kinetic energy of molecules really only depends on the temperature.

What type of wave do the contractions of the snake muscles make as the snake moves forward
S_A_V [24]
Actually, there are four kinds of reptile motion: 

Concertina - vermiform. Circular muscles around the snake squeeze the front of the snake's body out long, then the latter half is pulled forward. 

Rectilinear crawling - Belly scutes are moved forward individually in a wave-like motion. 

Side-winding - Snake's version of "walking". Use by several species to move over fluidic substrates, such as sand. 

Lateral undulation - Most common form of movement. Snake presses on alternating pressure points to force body forward (or backward)
