Answer:

**Answer:**

(a) Surface energy is greater than grain boundary energy due to the fact that the bonds of the atoms on the surface are lower than those of the atoms at the grain boundary. The energy is also directly proportional to the number of bonds created.

(b) The energy of a high-angle grain boundary is higher than that of a small-angle grain boundary because the high-angle grain boundary has a higher misalignment and smaller number of bonds than a small-angle grain boundary.

Time needed to cool the watermelons is:

**Answer:**

**558.1918 kilocalories = 558191.8 calories**

**Explanation:**

Data provided in the question:

Atmospheric pressure = 84.6 KPa

Mass of water, m = 900 g = 0.90 kg

Temperature = 15°C

Now,

Temperature at 84.6 KPa = 94.77°C

Therefore,

Heat energy required = m(CΔT + L)

here,

C is the specific heat of the water = 4.2 KJ/kg.°C

L = Latent heat of water = 2260 KJ/kg

Thus,

Heat energy required = 0.90[ 4.2 × (94.77 - 15) + 2260 ]

= 2335.53 KJ

also,

1 KJ = 0.239 Kilocalories

Therefore,

2335.53 KJ = 0.239 × 2335.53 Kilocalories

= **558.1918 kilocalories = 558191.8 calories**

**Answer:**

The answer is "**0.147 nm and 99.63 mol %**"

**formula:**

** **

**In point (b):**

**formula:**

that's why the composition value equal to 99.63 %

**Answer:**

101.42235 kPa

**Explanation:**

The unit inHg means "inches of mercury", Its a pressure unit commonly used by the US aviators.

The conversion value to KPa (kilopascal) is

1 inHg= 3.386389 kPa

So now we only have to multiply:

29.95 inHg * 3.386389 kPa/in Hg =101.42235 kPa
