What’s Is Example Of
ahrayia [7]

*heat transfer energy, As it always flow from higher temperature to lower temperature till it reach the thermal equilibrium.

example: -friction.

- collisions.

- the hot cup which's hotter than your hand✋will transfer heat in your hand. and a cold piece of ice which's colder than your hand to causing the heat transfer out of your hand .

*temperature ️ depends on the move of particle and we have a different shape of motion like:

translational motion.

rotational motion.

vibrational motion.

when the temperature:

increases it has more kinetic energy and faster moving particles and the object expanded which known as (thermal expansion).

decreases it has less kinetic energy and slower moving particles.

As kinetic energy is 1/2 mV².

example: -the mercury in thermometers.

*Absolute zero :

The theoretical temperature at which substances possess no thermal energy, equal to 0 K, −273.15°C, or −459.67°F.

*specific heat "c" :

is essentially a measure of how thermally insensitive a substance is to the addition of energy.

c=Q/m∆T

where Q is energy .

note water has a higher specific heat, and lower temperature.

*conduction <em><u>example</u></em> When the stove is turned on, the skillet becomes very hot due to the conduction of heat from the burner to the skillet.

Aleonysh [2.5K]

Answer:

L = 0.635m

Explanation:

This problem involves the concept of stationary waves in pipes. For pipes closed at one end,

The frequency f = nv/4L for n = 1,3,5....n

For pipes open at both ends

f = nv/2L for n = 1,2,3,4...n

Assuming the pipe is closed at one end and that velocity of sound is 343m/s in air. If we are right we will obtain a whole number for n.

The film solution can be found in the attachment below.
