Answer: Option (B) is the correct answer.

Explanation:

Heat of fusion is defined as the heat energy required to convert a solid substance in liquid state.

So, when we heat a solid substance then the heat absorbed by it helps in breaking of intermolecular forces of attraction. As a result, solid substance will start to melt and during this change the temperature remains constant until the substance completely melts which is known as latent heat of fusion.

Hence, we can conclude that the temperature of a substance remains constant as its heat of fusion is added to melt the substance.

Solids have:<br> fixed shape<br> O A and B<br> fixed size<br> neither A nor B
Lemur [1.5K]

<u>Answer:</u>

<em>B. A and B</em>

<em></em>

<u>Explanation:</u>

1. Solids have a definite volume, definite size and definite shape

2. The particles present in a solid are very closely packed since the intermolecular forces between them are very strong. The molecules do not move apart.

3. Melting point is the temperature at which solid changes into a liquid.

4. When a solid is heated to the melting point the intermolecular forces are overcome by the energy and the molecules present in it moves from its fixed position to take its liquid state which is called as melting.

When 55.0 grams of metal at 75.0°C is added to 100. grams of water at 15.0°C, the temperature of the water rises to 18.7°C. Assu
olga2289 [7]

Answer:

The specific heat of the metal is 0,50 J/gºC

Explanation:

Assume that no heat is lost to the surroundings

(Q = m . C . ΔT)metal + (Q = m . C . ΔT)water = 0

Let's replace our values.

55g . C . (18,7ºC - 75ºC) + 100g . 4,184 J/g·°C . (18,7ºC - 15ºC) = 0

55g . C . -56,3 ºC + 418,4J/·°C . 3,7ºC = 0

-3096,5 gºC . C + 1548,08 J = 0

1548,08 J = 3096,5 gºC . C

1548,08 J / 3096,5 gºC  = C = 0,50 J/gºC
