What's the difference between heat and temperature?

2 answers:

Heat and Temperature are physical properties of a body. While heat is a form of energy, temperature is a measure of how hot a body is. Temperature is directly proportional to the heat of the body, so when heat is introduced, the temperature of the body increases. Hope this helped!

Answer:

Heat is the transfer of thermal energy between molecules within a system and is measured in Joules (J). It measures how energy moves or flows. Temperature is the average kinetic energy of molecules within a material or system and is measured in Celcius (°C), Kelvin (K), Fahrenheit (°F), or Rankine (R).

During the operation of fan we know that it is working on the electricity

So here when we connect the fan with electricity it uses the electrical energy and convert that energy into mechanical energy of fan

Fan uses this electrical energy to rotate the blades of fan and then it gives the high speed air to us

So here correct answer must be

motion energy

What is the difference between kinetic and potential energy and how do they work?

Iteru [2.4K]

To explain, I will use the equations for kinetic and potential energy:

$PE = mgh\\KE = \frac{1}{2}mv^{2}$

<h3>Potential energy </h3>

Potential energy is the potential an object has to move due to gravity. An object can only have potential energy if 1) <u>gravity is present</u> and 2) <u>it is above the ground at height h</u>. If gravity = 0 or height = 0, there is no potential energy. Example:

An object of 5 kg is sitting on a table 5 meters above the ground on earth (g = 9.8 m/s^2). What is the object's gravitational potential energy? <u>(answer: 5*5*9.8 = 245 J</u>)

(gravitational potential energy is potential energy)

<h3>Kinetic energy</h3>

Kinetic energy is the energy of an object has while in motion. An object can only have kinetic energy if the object has a non-zero velocity (it is moving and not stationary). An example:

An object of 5 kg is moving at 5 m/s. What is the object's kinetic energy? (<u>answer: 5*5 = 25 J</u>)

<h3>Kinetic and Potential Energy</h3>

Sometimes, an object can have both kinetic and potential energy. If an object is moving (kinetic energy) and is above the ground (potential), it will have both. To find the total (mechanical) energy, you can add the kinetic and potential energies together. An example:

An object of 5 kg is moving on a 5 meter table at 10 m/s. What is the objects mechanical (total) energy? (<u>answer: KE = .5(5)(10^2) = 250 J; PE = (5)(9.8)(5) = 245 J; total: 245 + 250 = 495 J</u>)

si tienes 2 circuitos uno en serie y otro en paralelo con el mismo valor en sus resistencias, para cuál circuito la resistencia

Novosadov [1.4K]

Answer:

circuito paralelo

Explanation:

Siempre el circuito en paralelo dara una resistencia menor. Recuerda que las resistencias se suman en el circuito en serie, an cambio en el circuito en paralelo, la corriente se bifurca de manera de circular con mayor intensidad por las ramas que tengan menos resistencia, y tal situacion llevara siempre a producir una menor resistencia equivalente.

Why isn’t our constitution ( and our country) in a constant state of adjustment and readjustment

madam [21]

The constitution and the country aren't in a constant state of adjustment and readjustment because it has strong and logical ideological bases that encompass most of society's issues over time.

The constitution was written on a democratic ideological basis inspired by the European Enlightenment revolution of thought. These principles have contributed to the construction of American social logic.

Therefore, the constitution and the country have not needed major readjustments or adjustments since their creation because the country has been built on solid and well-defined ideological bases that are projected into the future with a social logic.
