State one factor that effects the rate of change of the liquid colour​
Debora [2.8K]

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.

If my answer helped, kindly mark me as the brainliest!!

Thank You!!

scoundrel [369]

Answer:

protons

These particles do not vary in quality from one element to another; rather, what gives an element its distinctive identification is the quantity of its protons, called its atomic number. Protons and neutrons contribute nearly all of an atom's mass; the number of protons and neutrons is an element's mass number

Calculate the speed of sound wave with a frequency of 20hz and a wave length of 3.00m
Marta_Voda [28]
Wavelength is the distance of one frequency wave peak to the other and is most commonly associated with the electromagnetic spectrum.[1] Calculating wavelength is dependent upon the information you are given. If you know the speed and frequency of the wave, you can use the basic formula for wavelength. If you want to determine the wavelength of light given the specific energy of a photon, you would use the energy equation. Calculating wavelength is easy as long as you know the correct equation.
