The heat moves from the hot chocolate to the handle of the spoon by a process called thermal conduction.
It is the transfer of heat energy from one object to another when they are in contact with eachother.
Hope this answers your question.

Explanation:
at the dewpoint.......water will condense out of the air onto the surface
The times and distances are represented by the function are
- at 2 hours, the traveler is 725 miles from home.
- at 3 hours, the distance is constant, at 875 miles
- the total distance from home after 6 hours is 1,062.5 miles.
<h3>What is distance?</h3>
The distance is the length of path travelled by a body when moving with some speed and taking time t.
Given function is
D (t) = 300t +125 for 0≤t<2.5
D (t) = 875 for 2.5 ≤t≤3.5
D(t)= 75t +612.5 for 3.5<t≤6
According to the given function, for 2 hours, the traveler will travel from home,
D (2) = 300x2 +125 = 725 miles.
For time between 2.5 to 3.5 hr, the distance is constant i.e. 875 miles.
For total time 6hr, the distance travelled will be
D(6) = 75 x 6 +612.5 = 1062.5 miles.
Thus, the correct options are picked up.

All waves have an amplitude, wavelength, and frequency.
Amplitude is how far away the wave moves from its resting place. When drawn on a graph, the amplitude is the distance between the upper (crests) and lower (troughs) points and their center on the wave.
Wavelength is the distance two crests or troughs are away from each other.
Frequency is the number of waves produced in a set amount of time. The unit used to measure frequency is Hertz (Hz).
With sound waves, the frequency determines the pitch. The higher the frequency, the higher the pitch, and vice versa. So, a bass drum, which has a low pitch, would have a lower frequency than a mosquito's whine, which is very high pitched.
Light waves are actually electromagnetic waves. Their frequency determines what kind of wave they are, whether it's gamma rays, ultraviolet, x-rays, or something else.
