The correct answer is A. Transfers energy to another atom or molecule.

Explanation:

In physics, heat is produced by the inner energy of a substance or the transfer of heat from one body to another. In terms of inner energy, this is the result of the collision between particles or atoms. This can be explained as every time a particle or atom collides with others part of the energy of the atom is transferred, and this leads to heat. According to this, heat is conducted when one atom or molecule collied with and transfers energy to another atom or molecule.

Is it possible for a gas contained in a chamber to maintain a constant temperature while heat is being added to the gas? Explain

Evgesh-ka [11]

Answer:Yes

Explanation:

Yes it is possible for a gas contained in a chamber to maintain a constant temperature while heat is being added to the gas.A process in which temperature of the gas remains constant is called Isothermal Process.For an ideal internal energy is a function of temperature therefore internal energy remains constant while all the heat added is converted to do the work done by the system.

evaluate the force of a skateboard exerts on you if your mass is 60kg and you push on the skateboard with a force of 60N

Sav [38]

Every action has an equal or opposite reaction.
You weigh 60kg
So your acceleration is 6N / 60 kg = 0.1m/s^2

What happens to the reaction 2 N O 2 in equilibrium with N 2 O 4 plus 57.3 kilojoules when the temperature of the reaction is in

Burka [1]

Answer:

More reactant forms.

Explanation:

Given reaction is,

$2NO_{2}$ ⇒ $N_{2} O_{4}+57.3 KiloJoules$ per mole

This is an Exothermic Reaction,(ΔE=-57.3KJper mole)

We know the equilibrium point of all Exothermic reactions moves leftward and more reactant is formed at the equilibrium.

Reason:

As heat is being produced in the reaction the additional heat(57.3KJpermole) can be thought of as a product of the reaction.

So,if you increase the temperature ,you provide heat energy,

(in other words heat energy is given) and hence the concentration of the products increases.

So, with respect to LeChateliers Principle,

As the concentration of products is increased by external means,more of the reactants are produced at the equilibrium of the reaction.

Therefore amount of reactants increases as more reactant forms.
