During the melting of ice in the mouth, the mouth loses heat and feels colder.

<h3>What is the heat change that occurs in melting?</h3>

Melting is the process by which when a solid absorbs heat from the surroundings, it changes to liquid.

Therefore, the melting of a solid is an endothermic process.

In the system of ice melting in the mouth, the ice molecule absorbs heat energy from the mouth in order to melt.

Similarly, when the temperature of the water rose to 10.0 degrees, the water at 0.00 degrees absorbs heat from the mouth.

Therefore, the mouth loses heat and feels colder.

In conclusion, the melting of ice involves ice absorbing heat from the surroundings.

Alexeev081 [22]

Answer:

5.6 L

Explanation:

We can apply Charles' Law here since our pressure is constant (will not change inside the refrigerator) and we are relating change in volume with change in temperature:

V₁ / T₁ = V₂ / T₂ where V₁ and T₁ are initial volume and temperature, and V₂ and T₂ are final volume and temperature. Let's plug in what we know and solve for the unknown:

28.0 L / 25 °C = V₂ / 5 °C => V₂ = 5.6 L

5.6 L is our new volume (at 5 °C).

The metallic radius of a potassium atom is 231 pm. What is the volume of a potassium atom in cubic meters?
Sauron [17]
1 pm = 10∧-10 cm
Therefore, 230 pm is equivalent to 2.3 ×10∧-8 cm.
Atom is in the shape of a sphere,
The volume of a sphere is given by 4/3πr³
Thus, volume of the atom = 4/3π( 2.3 ×10∧-8)³
                                          = 4/3 (3.142 ×12.167×10∧-24
                                           = 5.096 ×10∧-23 cm³
but 1m³= 1000000cm³
Therefore, the volume of the atom = 5.096 ×10∧-29 m³
