Answer:

sublimation, melting, melting, sublimation

Step-by-step explanation:

Melting is defined by a process when any matter being in its solid state changes its state to liquid when introduced to heat while sublimation is a process when the matter in solid state changes directly to gaseous state when introduced to heat.

therefore,

"Iodide produces fumes when heating" is sublimation.

"An iceberg turn to ocean water" is melting.

"Candle wax turns to liquid when hot" is melting.

"Fog is created from dry ice" is sublimation.

Answer:

iodide produces fumes when heated - sublimation

An iceberg turns to ocean water - melting

Candle wax turns to liquid when hot - melting

"Fog" is created from dry ice - sublimation

Step-by-step explanation:

Melting is the substance changing from a solid to a liquid.

Sublimation is when a substance changes directly from a solid to a gas without a liquid phase.

Step-by-step explanation:

1. 1*1/6= 1 /6=1.67

2. 9*7/10= 63/10= 6.3

3. 7*4/8= 28/8= 3.5

4. 1/2 of 2= 1/2*2= 0.5*2= 1

5. 1/12 of 2= 1/12*2= 8.33*2= 16.66

6.2/6 of 2= 2/6*2= 3.33*2= 6.66

7. 1/3 of 5= 1/3*5= 3.33*5= 16.65

8. 3/10 of 8= 3/10*8= 0.3*8= 2.4

The figure below is a square. Find the length of side x in simplest radical form with a rational denominator.

Mashcka [7]

Answer:

$\frac{\sqrt{10}}{2}$

Step-by-step explanation:

The diagonal forms two 45-45-90 triangles, with the diagonal being the hypotenuse of both. The Pythagorean Theorem states that $a^2+b^2=c^2$ , where $c$ is the hypotenuse of the triangle, and $a$ and $b$ are the two legs of the triangle.

From the Isosceles Base Theorem, the two legs of a 45-45-90 triangle are always equal. Since we're given a diagonal of $\sqrt{5}$ , we have:

$x^2+x^2=\sqrt{5}^2,\\2x^2=5,\\x^2=\frac{5}{2},\\x=\sqrt{\frac{5}{2}}=\frac{\sqrt{5}}{\sqrt{2}}=\frac{\sqrt{5}}{\sqrt{2}}\cdot \frac{\sqrt{2}}{\sqrt{2}}=\boxed{\frac{\sqrt{10}}{2}}$
