Answer:
Temperature is one of the major factors that affects the rate of change of the liquid colour, this is because ; like when if you freeze hot water the ice formed will be clear transparent, while on the other hand, if we freeze cold water it would be foggy inside the ice. This change occurs because of the temperature difference of the cold and hot water.

answer:
tehehehe mix red and white!
Explanation:
Given that
Mass of water = 65.34 g
Amount of heat = mass of water * specific heat (temperature change
)
= 65.34 g * 4.184 J / g-C ( 21.75-18.43 )C
= 907.63 J
= 0.908 KJ
And
1 cal = 4.186798 J
907.63 J * 1 cal / 4.186798 J =216.78 cal
Or0.218 kcal
Answer:
Wavelength of sound waves millimetres
Explanation:
The speed of any wave is equal to the product of its wavelength and frequency.
This can be represented mathematically as
Where
V is the speed of sound waves
f is the frequency of sound waves
and
is the wavelength of the sound waves.
Substituting the given values in above equation we get -
meters
millimetres
