The molar heat of fusion of platinum (Pt) is 4.700 kcal/mol. How much heat must be added to 85.5 g of
zvonat [6]

Answer:

2.07 Kcal heat must be added to completely melt the platinum.

Explanation:

Given data:

Molar heat of fusion =  4.700 Kcal / mol

Mass of platinum = 85.5 g

Heat of fusion = ?

Solution:

Formula:

ΔH = n × molar heat of fusion

n = number of moles

Now we will calculate the number of moles:

Number of moles = mass / molar mass

Number of moles = 85.5 g /195.08 g/mol

Number of moles = 0.44 mole

ΔH = n × molar heat of fusion

ΔH = 0.44 mol × 4.700 Kcal / mol

ΔH = 2.07 Kcal

Identify the state(s) of matter that each property describes.
DIA [1.3K]

Answer:

1) takes the shape of its container ( liquid and gas).

2) fills all available space (gas)

3) maintains its shape ( solid)

4) can be poured ( liquid)

5) is compressible ( gas)

6) has a fixed volume ( liquid and solid)

Explanation:

Matter is simply defined as anything that has weight and occupies space. It exists in three states, namely: solid, liquid and gaseous states.

The properties of different states of matter includes:

SOLID STATE

--> It has a definite shape: The shape of a solid is fixed; it does not depend on the shape of other materials.

--> It has a definite volume: it occupies its own shape due to the force of cohesion among its molecules.

--> It is tightly packed: The molecular movements of particles are negligible.

LIQUID STATE

--> liquid has a defined volume.

--> it has no definite shape: There is no specific shape of a liquid. It occupies any available space. It's shape depends on the shape of the container into which it is poured.

GASEOUS STATE

--> it has no fixed shape: Due to the distance in the molecules of gas, the gaseous state has no shape. It occupies the shape of its container.

--> It has no fixed volume: it occupies the shape of any container that is closed.

--> It is highly compressible: The particles of gas are far off from one another and there is room for collision.

A hypothetical substance has a melting point of −10°C and a boiling point of 155°C. If this substance is heated from 2°C to the
likoan [24]

Answer:

Option 3. Specific heat capacity of the liquid

Explanation:

Let's think, the states for the substance.

In -10, substance turns from solid state to liquid, so at 2°C , state is liquid.

We have to take from liquid state at 2°C to 155°C, which is the boiling point.

As the substance doesn't change its state, we only have to apply the specific heat capacity of the liquid.

1. specific heat capacity of the solid → This is used, when the substance is solid.

2. Heat of fusion → Only used when you turn from liquid to solid

4. Heat of vaporization → Used when the substance changes its state from liquid to gas

5. specific heat capacity of the gas → Used when the substance is a gas.
