What is the tool used for measuring volume?

RoseWind [281]

Answer:

Liquid volume is usually measured using either a graduated cylinder or a buret. As the name implies, a graduated cylinder is a cylindrical glass or plastic tube sealed at one end, with a calibrated scale etched (or marked) on the outside wall.

What change in volume results if 75.0 mL of gas is cooled from 100.0 °C<br> to 0.00 °C

Ksenya-84 [330]

Answer:

Final volume v2 = 0 ml

Explanation:

Given:

Initial temperature = 100°C

Initial volume = 75 ml

Final temperature = 0°C

Find:

Final volume

Computation:

Using Charles law formula;

⇒ V1 / T1 = V2 / T2

Where

⇒ Initial temperature = T1

⇒ Initial volume = V1

⇒ Final temperature = T2

⇒ Final volume = V2

So,

⇒ 75 / 100 = V2 / 0

Final volume v2 = 0 ml

Before entering the cyclotron, the particles are accelerated by a potential difference V. Find the speed v with which the partic

vesna_86 [32]

Answer:

Speed, $v=\sqrt{\dfrac{2qV}{m}}$

Explanation:

The device which is used to accelerate charged particles to higher energies is called a cyclotron. It is based on the principle that the particle when placed in a magnetic field will possess a magnetic force. Just because of this Lorentz force it moves in a circular path.

Let m, q and V are the mass, charge and potential difference at which the particle is accelerated.

The work done by the particles is equal to the kinetic energy stored in it such that,

$qV=\dfrac{1}{2}mv^2$

v is the speed with which the particles enter the cyclotron

So,

$v=\sqrt{\dfrac{2qV}{m}}$

So, the speed with which the particles enter the cyclotron is $v=\sqrt{\dfrac{2qV}{m}}$ . Hence, this is the required solution.
