Describe two variables that affect the rate of diffusion
Katyanochek1 [597]

Answer:

The two variables affecting the rate of diffusion are the concentration gradient and size of the molecule. Concentration gradient: The movement of the substance is generally along the concentration gradient of the solute and it moves from a region of its higher concentration to a region of its lower concentration.

ball has a volume of 5.27 liters and is at a temperature of 27.0°C. A pressure gauge attached to the ball reads 0.25 atmosphere.
Masja [62]

Answer:

The absolute pressure inside the ball is 1.25atm.

Explanation:

Given-

Volume, V = 5..27L

Temperature, T = 27°C

Gauge Pressure, Pg = 0.25 atm

Atmospheric pressure, Patm = 1 atm

Absolute pressure, Pabs = ?

We know,

Therefore, absolute pressure inside the ball is 1.25atm.

Name three properties of solids that are different from those of liquids. Explain the differences for each.
olga55 [171]
1) Solids have a fixed shape
The particles of solids are held into their positions and are only able to vibrate about fixed points. The strength of the bonding means that the particles have their own shape, which they retain, and do not take the form of the container they are in.

2) Solids may not flow
The molecules of liquids are able to slide past one another due to weaker bonds between particles. This allows the liquid to flow; whereas, this movement is not possible in solids so they cannot flow.

3) Solids may fracture
The fact that solids possess a rigid structure means that they have the ability to fracture. Although some are able to withstand more stress than others, all solids may break. This breakage occurs when the intermolecular bonds are mechanically broken. This is not possible in the case of liquids because such rigid intermolecular bonds do not exist.
