1.  Changing from solid to a liquid is called melting / fusion and happen

at the melting/ fusion point.

Reason: melting point is a temperature at which a solid melt and converts into liquid by providing heat.

2. Changing from liquid to gas is called evaporation/boiling and happens at the evaporation/boiling point.

Reason. Evaporation is a process in which molecules from surface of liquid convert into gas.

3.   Changing from a gas to a liquid  is called condensation and happens at the condensation point.

Reason : In condensation process  gas particles converts into liquid droplets.

4. Changing from liquid to a solid is called freezing and happens at the freezing point.

If the length of a building is 2 1 2 times the width and each dimension is increased by 7 ft, then the perimeter is 266 ft. Find
N76 [4]

Answer:

The original dimensions of the building is 95 ft × 38 ft.

Explanation:

Let the original length be 'l' and original width be 'w'.

Given:

Original length (l) = 2\frac{1}{2}\times original\ width

Original width = 'w'.

So, l=2\frac{1}{2}w=\frac{5}{2}w

Now, as per question:

Length and width is increased by 7 ft.

So, new length (l') = l+7=\frac{5w}{2}+7

New width (w') = w+7

New perimeter (P) = 266 ft

Perimeter is given as:

P=2(l' +w')\\\\266=2(\frac{5w}{2}+w)\\\\\frac{266}{2}=\frac{5w+2w}{2}\\\\266=7w\\\\w=\frac{266}{7}=38\ ft

Therefore, original width = 38 ft.

Original length is, l=\frac{5\times 38}{2}=\frac{190}{2}=95\ ft

Hence, the original dimensions of the building is 95 ft × 38 ft.
