Answer:

  • <u>Option-(C)-</u>  

Helium, He is the most lightest among the given four elements. As the molecular mass of helium,He is about  4.002602 u. It is considered the second most lightest element inside the periodic table after the hydrogen,H atom which is the lightest of all.

Explanation:

  • <u>Velocity dependence upon the molecular weight of the element:</u>

The molecular weight of the different elements gives them the very specific features including the ability to travel fast in a given space. While the helium,He is considered one of the lightest elements in the universe so, it has a greater velocity among the four options.

  • <u>For example:</u>

A person with less weight will run much faster as compared to a person having more weight.

The correct option is C.
Helium gas will have the highest velocity at a given temperature because it has the lowest atomic mass of all the gases given. The atomic mass of gases affect their rate of movement. The lower the atomic mass, the faster the gas molecules moves and the higher the atomic mass, the slower the gas molecules move.

s2008m [1.1K]

Answer:

a) increase exponentially.

Explanation:

The vapor pressure is depend only on temperature.

The vapor pressure of liquid does not depend upon amount of liquid. For example whether the liquid is 50 g or 30 g its vapor pressure will remain same according to the temperature.

The temperature and vapor pressure have exponential relationship. As the temperature of liquid increases its vapor pressure also goes to increase. When the temperature of liquid goes to decrease its vapor pressure also decreases.

The change in vapor pressure of substance when temperature changes is given as,

ln P₂/P₁ = ΔH(va)/R (1/T₁ - 1/T₂)

. What happens the pH of an acid solution as a base is added?​
Dmitrij [34]

As a base is added to an acidic solution, the H+ ions in solution that make it acidic are slowly neutralized into water (via OH-, the base). As these ions are converted into water the concentration of them decreases, so the pH decreases, as they are directly related.

Hope this helps!

A cathode ray tube is made of glass with a small amount of some kind of gas in it. It has metal electrodes at each end to pick u
Butoxors [25]

Answer:

One of the main uses of the cathode ray tube is in the Cathode  ray oscilloscope

Explanation:

Cathode rays are produced when a gas in an evacuated glass at very low pressure and high pressure breaks up into positive and negative ions. the negative ions move towards the anode(positive electrode) while the positive ions move towards the cathode(negative electrode), and there they knock off electrons (which are known as cathode rays) from the metal plate of the cathode.

Cathode ray tubes are mainly used in oscilloscopes, television picture tubes and in computer screens.

The cathode ray oscilloscope is used in a.c. and d.c. voltage measurements, observation of waveforms, time measurements, etc.
