Greeley [361]

Use Charles' Law: V1/T1 = V2/T2. We assume the pressure and mass of the helium is constant. The units for temperature must be in Kelvin to use this equation (x °C = x + 273.15 K).

We want to solve for the new volume after the temperature is increased from 25 °C (298.15 K) to 55 °C (328.15 K). Since the volume and temperature of a gas at a constant pressure are directly proportional to each other, we should expect the new volume of the balloon to be greater than the initial 45 L.

Rearranging Charles' Law to solve for V2, we get V2 = V1T2/T1.  

(45 L)(328.15 K)/(298.15 K) = 49.5 ≈ 50 L (if we're considering sig figs).

ziro4ka [17]

Any physical matter that is obtained or made from plants, animals, or the ground without undergoing a chemical process is called a natural material. This is a true statement.

<h3>Features of natural materials</h3>

Natural materials are the physical matters that are made from plants, animals and ground(environment) which has not been subjected to any chemical processes for modification.

But any natural material that has undergone any chemical process which has been designed and manufactured to fulfil a particular purpose is called a synthetic material.

Therefore, any physical matter that is obtained or made from plants, animals, or the ground without undergoing a chemical process is called a natural material.

David is making lemonade he asked you could you some lemon juice and water the sugar starts to dissolve what can we do to speed
suter [353]

We could (a) stir faster and (b) warm the mixture.

<em>Stirring faster</em> moves freshly-dissolved sugar away from the solid and allows new water molecules to contact with the surface,

<em>Warming the mixture</em> gives the water molecules more kinetic energy, so their collisions with the surface of the sugar will be more effective in removing the sugar molecules.

Consider a mixture of oil and water. What terms would you use to describe this mixture? Check all that apply. Heterogeneous homo
GenaCL600 [577]

A mixture of oil and water is:

Heterogeneous

immiscible

<h3>What type of mixture of oil and water is?</h3>

The water molecules attract each other, and the oil molecules stick together. That causes oil and water to form two separate layers. Water molecules pack closer together, so they sink to the bottom, leaving oil sitting on top of the water. The mixture can be called as Emulsion. It is an immiscible liquid and the mixture is heterogeneous as oil floats on top of water surface but do not mix with it.

Thus, correct options are Heterogeneous and immiscible.
