Explain,in terms of particles,how heat is transferred through the glass wall of a boiling tube

1 answer:

4 0

Considering the great topic of thermodynamics (assuming normal atmospheric pressure):

Keep in mind that hotness (temperature) and heat are related but not the same thing. Each time water goes from one state to another, it requires the gain or loss of heat.
In this case the boiling water is gaining heat, the water molecules are vibrating faster with more kinetic energy (energy of motion). The (heat) energy is transferred by the rapid movement of particles colliding with other particles.

Are fat fish more likely to have broad stripes than thin fish?

maw [93]

yes, just like human skin. The bigger you grown the more your skin stretches, I a fish is bigger their skin will stretch leading to broad stripes.

Three small but dense objects are located in the x-y plane as shown in the figure. The objects have the following masses: mA = 3

satela [25.4K]

The x and the y coordinates of the center of the mass of this system will be 43.1 m and 3.12 m respectively.

<h3>What is the center of mass?</h3>

A location is established in relation to an object or set of objects in the center of mass. It is the system's average position across all of its components.

Given data;

There are three little objects that are densely spaced out in the x-y plane.;

The value of the masses

m₁=1.41 kg

m₂=2.55 kg

m₃=3.19 kg

$\rm X_{cm} =\frac{ (W_1x_1 + W_2x_2 + W_3x_3)}{(W_1 + W_2 + W_3)} \\\\\ X_{cm} ==\frac{1.41 \times 2 + 2.55 \times 6 +3.19 \times 4}{1.41+2.55+3.19} \\\\ X_{cm} =4.31 \ m$

$\rm Y_{cm} =\frac{ (W_1y_1 + W_2y_2 + W_3y_3)}{(W_1 + W_2 + W_3)} \\\\\ X_{cm} ==\frac{1.41 \times 2 + 2.55 \times 4 +3.19 \times 7}{1.41+2.55+3.19} \\\\ X_{cm} =3.12 \ m$

Hence, the x and the y coordinates of the center of the mass of this system will be 4.31 m and 3.12 m respectively.

In Hooke’s law, what does the x represent?

Mice21 [21]

Answer: C

X = Displacement of the spring

Hooke's law: It states that the applied force F is proportional to the displacement of spring .

F ∝ x

Where, x = displacement of spring in meters

F = force, measured in Newtons

In another words The force F is equal to the constant K times the disparagement.

F = k.x

Where k is constant and it depends on elastic material.

Spring has restorative force.

If the spring moves in opposite direction then,

F = - k.x

A negative sign indicates that the spring resists and force is to the left. The compression of the spring is greater than the restoring force.

Example: A mass 'm' stretches a spring at a displacement x.
