What is the main cause of any change of state?
svetoff [14.1K]

Answer:

Adding or removing energy from matter causes a physical change as matter moves from one state to another. For example, adding thermal energy (heat) to liquid water causes it to become steam or vapor (a gas). And removing energy from liquid water causes it to become ice (a solid).

krok68 [10]

Answer:

The value of x will be "1.4".

Explanation:

The given values are:

y = 9.6

z = 4.0

The relation between x, y and z is:

⇒ z = \frac{y}{x}

and,

⇒ x=\frac{y}{z}

On substituting the given values, we get

⇒    =\frac{5.6}{4.0}
