Is the freezing point of water a physical change or a physical property​

Answer:

Physical change, because it isn't reacting to something; water being frozen doesn't change the fact that it is still water, even if it is in a different state.

Answer:

It is a physical change because this change is reversible and no chemical reaction occurs.

Consider the relationship (y+3)2 = b/(x-2), where y and x are variables and bis a constant. On rectangular coordinate paper, wha
Nikolay [14]

Answer:

(-1) is the slope of a graph of In(y+3) on the vertical axis versus In(x-2) on the horizontal axis.

Explanation:

\frac{(y+3)}{2} = \frac{b}{(x-2)}

Taking natural logarithm on both the sides:

\ln [(y+3)]-\ln[2]=\ln [b]-\ln [(x-2)]

\ln [(y+3)]=\ln[2]+\ln [b]-\ln [(x-2)]

\ln [(y+3)]=\ln {[2\times b]-\ln [(x-2)]

Slope intercept form is generally given as:

y=mx+c

m = slope, c  = intercept on y axis or vertical axis

On rearranging equation:

\ln [(y+3)]=(-1)\times \ln [(x-2)]+\ln {2b}

y = ln [(y+3)], x = ln [(x-2)], m=-1 , c  = ln 2b

(-1) is the slope of a graph of In(y+3) on the vertical axis versus In(x-2) on the horizontal axis.

1. Gases are made up of molecules which are relatively far apart.2. The molecules are in motion at high speeds.3. The molecular
Katen [24]

Answer:

A

Explanation:

Molecules of a gas are relatively more compressible than those of liquids and solids because they are relatively far apart without any intermolecular forces between them. However, at lower temperature and higher pressure, there is now a significant intermolecular interaction between the gas molecules and they are no longer relatively far apart. Hence they are more compressible than liquids and solids which already possess significant intermolecular interaction and thus a definite volume.
