Answer:
The false statement is: 3. Because liquid water and liquid carbon tetrachloride do not mix, neither do their vapors
Explanation:
Gas is a state of matter, that has <u>less density than liquids and solids</u>. The gaseous particles have low intermolecular forces and thus they can move freely.
It is a very <u>compressible fluid</u> that has no fixed shape. Gas occupies the whole container in which it is stored, thus taking the shape of the container. Therefore, <u>the volume of the gas is equal to the volume of the container.</u>
<u>Polar liquid like water (H₂O) and nonpolar liquid like carbon tetrachloride, are immiscible. However, in the gaseous state, their vapors form a homogeneous mixture.</u>
Special properties of water are its high heat capacity and heat of vaporization, its ability to dissolve polar molecules, its cohesive and adhesive properties, and its dissociation into ions that leads to generating pH. Understanding these characteristics of water helps to elucidate its importance in maintaining life.
Hey there,
A scientist triples the temperature of a gas at constant pressure. By what factor does the gas’s volume change?
I believe that when the scientist triples the temperature of the gas at a certain and constant pressure, the factor of the gas volume would change most likely with the double amount of pressure that the scientist put in the first place.

The osmotic pressure of the 0.250 L solution made with 1.60 g of glucose, in water at 25.00°C is 0.869atm.
<h3>How to calculate osmotic pressure?</h3>
The osmotic pressure of the solution can be calculated using the following expression:
PV = nRT
where;
- P = pressure
- V = volume
- n = no of moles
- T = temperature
- R = gas law constant
no of moles of glucose = 1.60g ÷ 180g/mol = 8.89 × 10-³mol
P × 0.250 = 0.00889 × 0.08206 × 298
0.25P = 0.217
P = 0.217/0.25
P = 0.869atm
Therefore, the osmotic pressure of the 0.250 L solution made with 1.60 g of glucose, in water at 25.00°C is 0.869atm.
