Phase change occur in substances when the they change from one state of matter to another due to the addition or removal of heat.

<h3>What are phase changes?</h3>

Phase changes refers to the changes that occur in substances in which they change from one state of matter to another due to the addition or removal of heat.

The phase changes that occur in substances are as follows:

change from solid to liquid known as melting
change from liquid to gas known as vaporization
change from solid to gas known as sublimation
change from gas to solid known as deposition
change from gas to liquid known as condensation
change from liquid to solid known as freezing

Therefore, phase change occur in substances when the they change from one state of matter to another due to the addition or removal of heat.

Find the equation of the line passing through the points (2, 1) and (5, 10).

Vedmedyk [2.9K]

The equation : y=3x-5

<h3>Further explanation </h3>

Straight-line equations are mathematical equations that are described in the plane of cartesian coordinates

General formula

y-y1 = m(x-x1)

y = mx + c

Where

m = straight-line gradient which is the slope of the line

x1, y1 = the Cartesian coordinate that is crossed by the line

c = constant

The formula for a gradient (m) between 2 points in a line

m = Δy / Δx

Gradient

$\tt \dfrac{10-1}{5-2}=3$

Equation

$\tt y-1=3(x-2)\\\\y-1=3x-6\\\\y=3x-5$
