Ice has a specific heat of 2.093Jg ∘C, liquid water's specific heat is 4.184Jg ∘C, and steam has a specific heat of 1.864Jg ∘C.

Which phase of water will have the lowest temperature change upon heating, when the same amount of heat is applied to each?

Answer:

The liquid phase will have the lowest temperature change upon heating.

Explanation:

Assuming no phase change due to heating, we know that the temperature change, is proportional to the mass heated, being the proportionality constant  a quantity that depends on the material, and represents the resistance of the material to change the temperature, called specific heat.

So, if we assume that the mass is the same for the three phases, and that the amount of heat supplied is also the same,the phase with the highest specific heat will have the lowest temperature change.

So, the liquid phase will be the one that exhibits this behavior, as the specific heat of liquid water (4.184 J/gºC) is the highest among the three phases.

Which instrument produces the sound of a single frequency?
notka56 [123]
NO musical instrument produces a 'pure' tone with only a
single frequency in it.

EVERY instrument produces more or less harmonics (multiples)
in addition to the basic frequency it's playing.

The percussion instruments (drums etc) are the richest producers
of bunches of different frequencies.

Fuzzy electric guitars are next richest.

The strings and brass instruments are moderate producers of
harmonics ... I can't remember which is greater than the other.

Then come the woodwinds ... clarinet, oboe, etc.

The closest to 'pure' tones of single frequency are the sounds
made by the flute and piccolo, but even these are far from 'pure'.

The only way to get a true single-frequency sound is from an
electronic 'sine wave' generator.

A 950-kg car strikes a huge spring at a speed of 22m/s (fig. 11-54), compressing the spring 5.0m. (a) what is the spring stiffne
alukav5142 [94]

(a) The spring stiffness constant of the spring is 18,392 N/m.

(b) The time the car was in contact with the spring before it bounces off in the opposite direction is 0.23 s.

<h3>Kinetic energy of the car</h3>

The kinetic energy of the car is calculated as follows;

K.E = ¹/₂mv²

K.E = ¹/₂ x 950 x 22²

K.E = 229,900 J

<h3>Stiffness constant of the spring</h3>

The stiffness constant of the spring is calculated as follows;

K.E =  U = ¹/₂kx²

k = 2U/x²

k = (2 x 229,900)/(5)²

k = 18,392 N/m

<h3>Force exerted on the spring</h3>

F = kx

F = 18,392 x 5

F = 91,960 N

<h3>Time of impact</h3>

F = mv/t

t = mv/F

t = (950 x 22)/(91960)

t = 0.23 s

True or false as heat and pressure decreases one type of metamorphic rock will transform into another type
dezoksy [38]

Answer: True

Explanation:  Metamorphism is the changing of rocks by heat and pressure. During this process, rocks change either physically and/or chemically. They change so much that they become an entirely new rock. Figure 4.22: The platy layers in this large outcrop of metamorphic rock show the effects of pressure on rocks during metamorphism.

The jet fuel in an airplane has a mass of 97.5 kg and a density of 0.804 g/cm3. What is the volume of this jet fuel
Mnenie [13.5K]

The volume of the jet fuel is 1.213 x 10⁵ cm³.

<h3>What is density?</h3>

Density is a physical property that measures the ratio of mass to volume occupied by an object.

Density = mass/volume

Volume = mass/density

<h3> Volume of the jet fuel</h3>

The volume of the jet fuel is calculated as follows;

Volume = (97500 g)/(0.804 g/cm³)

Volume = 1.213 x 10⁵ cm³

Thus, the volume of the jet fuel is 1.213 x 10⁵ cm³.
