Nothing happens to these particles when it comes to size however if it were to be speed, the sample would increase.
Fact: The size of a particle will never change!

Answer: Size of the particles will never change

Explanation: When a sample liquid is heated in a closed container, the temperature increases and thereby increasing the speed of the particles which would try to escape the surface of water into the free space above the liquid. This process is known as Vaporization and since its a closed container, it will take the form of the condensed vapors on the surface lid of the container.

Thus in no process would the size of the particle change as temperature affects only the speed of the container, not the size of the particles.

What are the benefits and drawbacks to having a pouring temperature that is much higher than the metal’s melting temperature?

Mashcka [7]

Answer:

The main advantage would be that with the pouring temperature being much higher, there is very little chance that the metal will solidify in the mould while busy pouring. This will allow for moulds that are quite intricate to still be fully filled. The drawbacks, though, include an increased chance defects forming which relates to shrinkage (cold shots, shrinkage pores, etc). Another drawback includes entrained air being present, due to the viscosity of the metal being low because of the high pouring temperature.

What mass of powdered drink mix is needed to make a 0.5 M solution of 100 mL?

Maru [420]

Answer:

There is 17,114825 g of powdered drink mix needed

Explanation:

Step 1 : Calculate moles

As given, the concentration of the drink is 0.5 M, this means 0.5 mol / L

Since the volume is 100mL, we have to convert the concentration,

⇒0.5 / 1 = x /0.1 ⇒ 0.5* 0.1 = x = 0.05 M

This means there is 0.05 mol per 100mL

Step 2 : calculate mass of the powdered drink

here we use the formula n (mole) = m(mass) / M (Molar mass)

⇒ since powdered drink mix is usually made of sucrose (C12H22O11) and has a molar mass of 342.2965 g/mol.

0.05 mol = mass / 342.2965 g/mol

To find the mass, we isolate it ⇒0.05 mol * 342.2965 g/mol = 17,114825g

There is 17,114825 g of powdered drink mix needed

If Jerome is swinging on a rope and transferring energy from gravitational potential energy to kinetic energy, _____... is being

Pachacha [2.7K]

Answer;

-Work

If Jerome is swinging on a rope and transferring energy from gravitational potential energy to kinetic energy, work is being done.

Explanation;

Work refers to the application of a given force over a distance. Thus, we can say work is the product of force and distance.
Energy on the other hand is the ability of a body to change, its location, shape, or state of another body.
According to the work-Energy principle, a change in the kinetic energy, which is the energy possessed by a body in motion, is equivalent to the net work done on the body.

Determine the mass of each sample 1.55 kmol sulfur trioxide

xxMikexx [17]

Explanation:

Given parameters:

Number of moles of the sulfur trioxide = 1.55kmol = 1.55 x 10³mole

Unknown:

Mass of the sulfur trioxide = ?

Solution:

To solve for the mass of the sample of sulfur trioxide:

Find the molar mass of the compound i.e SO₃

atomic mass of S = 32g

O = 16g

molar mass = 32 + 3(16) = 80g/mol

Use the formula below:

mass of SO₃ = number of moles x molar mass

mass of SO₃ = 1.55 x 10³ x 80 = 124000g or 124kg
