Pressure raises the boiling point

Andrew [12]2 years ago

3 0

Answer:

b. pressure

Explanation:

The boiling point of a substance increases as the pressure increases. The boiling points of a liquid is the temperature at which the liquid converts to vapor. At this point the vapor pressure of the liquid is equal to the pressure surrounding the liquid.

Heating increases the temperature of liquid, thereby increasing the pressure . As pressure increases the energy required to boil also increases, causing an increase in the boiling points.

When gases dissolve in gases or when liquids and gases dissolve in liquids, _________eventually spreads the particles evenly thr

natulia [17]

When gases dissolve in gases or when liquids and gases dissolve in liquids, particles movement eventually spreads the particles evenly throughout the solvent resulting in a homogeneous mixture.

Explanation:

When gases dissolve in gases or when liquids and gases dissolve in liquids, particle movement eventually spreads the particles evenly throughout the solvent resulting in a homogeneous mixture.

Solid particles do not dissolve easily like liquids and gases dissolve. Solid particles when dissolved in solid the particles moves very little. After getting heated and becomes molten then they get mixed.

But in the liquids and gases atoms moves and the particles get eventually spread and also get mixed after cooled.

What does it mean to optimize a solution ? How are solutions optimize

Romashka [77]

Question

What does it mean to optimize a solution?

To find out best possible solution for a given problem within the given constraint is generally termed as optimization

How are solution optimize ?

To solve an optimization problem, begin by drawing a picture and introducing variables. Find an equation relating the variables. Find a function of one variable to describe the quantity that is to be minimized or maximized. Look for critical points to locate local extrema.

What is diffusion? How does the motion of gas molecules explain how a gas diffuses throughout a room?

Lady bird [3.3K]

Answer:

Diffusion in gases

Diffusion is driven by differences in concentration. When chemical substances such as perfume are let loose in a room, their particles mix with the particles of air. The particles of smelly gas are free to move quickly in all directions

Why is a balanced symbol equation better at describing the reaction than a word equation

AleksandrR [38]

Answer:

The advantages described below

Explanation:

Advantages of a balanced chemical equation versus word equation:

easier to read: chemical equations typically only take one line and they include all the relevant information needed. They are short-hand notations for what we describe in words.
balanced chemical equations show molar ratio in which reactants react and the molar ratio of the products. Those are coefficients in front of the species. This is typically not included in a word equation, for example, hydrochloric acid reacts with potassium hydroxide. The latter statement doesn't describe the molar ratio and stoichiometry.
includes relevant information, such as catalysts, temperature and pressure above the arrow in the equation. We wouldn't have this in a word equation most of the time.
shows the stoichiometry of each compound itself, e. g. if we state 'ammonia', we don't know what atoms it consists of as opposed to $NH_3]$ .
includes states of matter: aqueous, liquid, gas, solid. This would often be included in a word equation, however.
